This is a list of regional differences in the [[Pokémon games]].

==Main lists==
===Pokémon===
The [[Pokémon (species)|Pokémon species]] names were introduced in Japanese. Most Pokémon had their names changed in English, French, German, Chinese, Korean, and Thai. The English names are used in the Spanish and Italian games. Several other languages also use English Pokémon names in their {{pkmn|anime}} dubs.

====Pokémon types====
Some Pokémon [[type]]s changed between languages.

* {{t|Psychic}} is エスパー ''Esper'' in Japanese.
* {{t|Dark}} is あく ''Evil'' in Japanese.

====Pokémon categories====
Some [[Pokémon category|Pokémon categories]] changed between languages.

* {{p|Blastoise}}, {{p|Kabuto}}, and {{p|Kabutops}} (Japanese category: こうらポケモン ''Shell Pokémon''; English category: Shellfish Pokémon)
** The "Shellfish" word was a translation mistake. The Japanese version indicates that these Pokémon were originally intended to be "Shell Pokémon".
* {{p|Meowth}} (Japanese category: ばけねこポケモン ''Bakeneko Pokémon''; English category: Scratch Cat Pokémon)
** The Japanese category refers to {{wp|bakeneko}}, a supernatural cat in Japanese folklore, but this was lost in the English translation.
* {{p|Persian}} (Japanese category: シャムネコポケモン ''Siamese Cat Pokémon''; English category: Classy Cat Pokémon)
** The Japanese category refers to a real-life cat breed, the siamese cat.
* {{p|Kangaskhan}} (Japanese category: 	おやこポケモン ''Parent and Child Pokémon''; English category: Parent Pokémon)
** The Japanese category refers to both parent and child, but the child is not mentioned in the English translation.
* The Japanese word ねずみ generally can be equally translated as "mouse" or "rat". In Pokémon categories, this is usually translated as "mouse":
** {{p|Rattata}} and {{p|Raticate}} (Japanese category: ねずみポケモン; English category initially was "Rat Pokémon", but then changed to "Mouse Pokémon" in Generation III)
** {{p|Pikachu}}, {{p|Raichu}}, {{p|Sandshrew}}, and {{p|Sandslash}} (Japanese category: ねずみポケモン; English category: "Mouse Pokémon")
** {{p|Cyndaquil}} (Japanese category: ひねずみポケモン; English category: Fire Mouse Pokémon)
** {{p|Pichu}} (Japanese category: こねずみポケモン; English category: Tiny Mouse Pokémon)
** {{p|Marill}} (Japanese category: みずねずみポケモン; English category: Aqua Mouse Pokémon)
** {{p|Bidoof}} (Japanese category: まるねずみポケモン; English category: Plump Mouse Pokémon)

====Pokémon forms====
Some [[List of Pokémon with form differences|Pokémon form differences]] changed between languages.

* [[Dynamax]] and [[Gigantamax]] are  ダイマックス ''Daimax'' and キョダイマックス ''Kyodaimax'' in Japanese, respectively.
* {{p|Furfrou}}'s trims use the word "Trim" in English but カット ''Cut'' in Japanese. However, these words don't apply to Furfrou's default state, the Natural Form.
** Natural Form (Japanese: やせいのすがた ''Wild Form'')
*** The Japanese word やせい ''Wild'' also refers to [[wild Pokémon]].
** Debutante Trim (Japanese: レディカット ''Lady Cut'')
** Dandy Trim (Japanese: ジェントルカット ''Gentleman Cut'')
** Matron Trim (Japanese: マダムカット ''Madame Cut'')
** La Reine Trim (Japanese: クイーンカット ''Queen Cut'')
*** This trim uses an English name in the Japanese games, but a French name in the English games.
** Pharaoh Trim (Japanese: キングダムカット ''Kingdom Cut'')

===Moves===
{{main|List of moves in other languages}}

====Moves introduced in Generation I====
* {{m|Acid Armor}} (Japanese: とける ''Liquefy''). The Japanese name indicates that the user itself is melting. This is lost in the English translation, but is referenced in the move descriptions from [[Generation II]] onwards.
** The Japanese name does not include the words "Acid" or "Armor" in any way. "Acid" may have been added in the localization because this is a {{type|Poison}} move, even though several non-Poison Pokémon are able to learn it. "Armor" may have been added in the localization because this move raises the user's Defense.
* {{m|Cut}} (Japanese: いあいぎり ''{{wp|Iaido|Iai}} Cut''). The Japanese name refers to ''{{wp|iaido}}'', a {{wp|Japanese martial arts|Japanese martial art}}. Specifically, it refers to the technique of drawing a blade from its {{wp|scabbard}}, cutting down the opponent, then re-sheathing the blade.
* {{m|Guillotine}} (Japanese: ハサミギロチン ''Pincer Guillotine''). Several Pokémon that use this move have pincers, such as {{p|Kingler}} and {{p|Gliscor}}.
* {{m|Lovely Kiss}} (Japanese: あくまのキッス ''Demon's Kiss''). In some games, a small demon appears in the move animation. This is related to [[Generation II]] move {{m|Sweet Kiss}} (Japanese: てんしのキッス ''Angel's Kiss'').
* {{m|Metronome}} (Japanese: ゆびをふる ''Wag Finger''). The Japanese name refers to the wagging finger associated with the move, implying the user is randomly deciding a move from a list.  The move's English name refers to the regular ticks associated with the move, which sound like the device it is named after.
* {{m|Mirror Move}} (Japanese: オウムがえし ''Parrot Mimicry''). The reference to a parrot (a real-life bird) may be related to the fact that several Pokémon that can learn this move are {{t|Flying|birds}}, such as {{p|Pidgey}} and {{p|Chatot}}. However, this is lost in the English translation.
* {{m|Pay Day}} (Japanese: ネコにこばん ''Coin for a Cat''). The Japanese name of the move is an {{wp|idiom}} equivalent to "to cast {{wp|pearls before swine}}." The coins depicted in the move's animation are {{wp|Koban (coin)|koban}}, {{wp|gold coin}}s used in the {{wp|Edo period}} of {{wp|History of Japan#Medieval Japan (1185–1573/1600)|feudal Japan}}, the same type of coin as the one on {{p|Meowth}}'s head.
* {{m|Rest}} (Japanese: ねむる ''Sleep''). 
* {{m|Swift}} (Japanese: スピードスター ''Speed Star''). The move's animation includes stars being thrown at the target.
* {{m|Tail Whip}} (Japanese: しっぽをふる ''Tail Wag''). The move's description mentions that the user "wags its tail cutely, making opposing Pokémon less wary".
** The English name "Tail Whip" may incorrectly imply that the user strikes the foe with its tail like a whip, which is not the case in the games. However, in the manga [[Pokémon Adventures]], the Tail Whip user sometimes actually strikes its opponent with the tail, which may be consistent with the English name.
* {{m|Thunderbolt}} (Japanese: １０まんボルト ''100,000 Volts''). The number "100,000 volts" is mentioned in the Japanese name, but this is lost in the English translation.
* {{m|Waterfall}} (Japanese: たきのぼり ''Waterfall Climb''). The English name is simply the word "Waterfall", without mentioning the act of climbing waterfalls. Some move descriptions in the games further clarify that the user is actually charging with enough force to climb waterfalls.
** When this move debuted in Generation I, the moves didn't have in-game descriptions in the [[core series]] yet. As a result, in the English version of the [[Generation I]] [[core series]] games, there is no indication that this move is related to climbing waterfalls.
** The description about "charging with enough force to climb waterfalls" debuted in the {{jap|Pokémon Stadium|Japanese Pokémon Stadium}} (which was not released in English). This is also mentioned in the later games {{eng|Pokémon Stadium}} and [[Pokémon Stadium 2]], not only in Japanese but in English as well.
** In {{game2|Gold|Silver|Crystal}}, the Japanese move description also mentions "charging with enough force to climb waterfalls". However, the English version was shortened to simply "An aquatic charge attack." The only reference to climbing waterfalls in the English text is when [[Clair]] says only once after being defeated: "<sc>RisingBadge</sc> will enable your <sc>Pokémon</sc> to use the move for climbing {{m|waterfall}}s." From [[Generation III]] onwards, the English move description is closer to the Japanese version, indicating that the user is charging with enough force to climb waterfalls.
** In several games, a waterfall appears when this move is used in-battle. This may incorrectly suggest that the user is summoning a waterfall, which would be inconsistent with the move description.

====Moves introduced in Generation II====
* {{m|False Swipe}} (Japanese: みねうち ''{{jwp|峰打ち|Strike with the Back of the Sword}}''). False Swipe's Japanese name is a reference to katanas, which are designed to have a single cutting edge on one side, while the other side is mostly flat. Thus, striking the opponent with the flat side of the katana would not be fatal.
* {{m|Rain Dance}} (Japanese: あまごい ''Rain Prayer''). This is the amagoi, a Shinto prayer and rituals for rain.
** The Japanese name of this move is unrelated to dancing, therefore this is not a [[:Category:Dance moves|dance move]]. As such, Rain Dance is unaffected by {{a|Dancer}}, and [[Tierno]] does not request to see a Pokémon with this move in {{g|X and Y}}. In several anime and manga depictions, the user is not seen dancing at all.
* {{m|Sweet Kiss}} (Japanese: てんしのキッス ''Angel's Kiss''). In some games, a small angel appears in the move animation. This is related to [[Generation I]] move {{m|Lovely Kiss}} (Japanese: あくまのキッス ''Demon's Kiss'').

====Moves introduced in Generation III====
* {{m|Aerial Ace}} (Japanese: つばめがえし ''{{wp|Sasaki Kojirō#Swallow cut|Swallow Return}}''). The Japanese name references {{wp|Sasaki Kojirō}}'s "{{wp|Sasaki Kojirō#Swallow Cut|Turning Swallow Cut}}" sword technique, so named due to its resemblance to the motion of a swallow's tail in flight. The cut is usually construed as a quick upward slash followed by a second one down the same direction, same as the move's animation. As such, it is learned by many Pokémon that are not {{type|Flying}}.
* {{m|Assist}} (Japanese: ねこのて ''Cat's Paw''). The Japanese name is likely a reference to the saying 猫の手も借りたい ''neko no te mo karitai'', which translates to "I would even like to borrow a cat's hands" ("I would even like a cat to assist me"), which means "I need all the help I can get". This is reflected by the way the move works, and that many feline Pokémon are capable of learning it. In some games, a cat's paw appears in the move animation.

====Moves introduced in Generation IV====
* {{m|Sucker Punch}} (Japanese: ふいうち ''Surprise Attack''). The Japanese name is unrelated to punching. This move can be learned by some Pokémon without arms, such as {{p|Arbok}}, {{p|Gastly}}, and {{p|Electrode}}. It is also unaffected by the Ability {{a|Iron Fist}}, which raises the power of [[:Category:Punching moves|punching moves]].

===Abilities===

===Items===
{{main|List of items in other languages}}

====Items introduced in Generation I====
* Three [[Poké Ball]]s introduced in Generation I had their names changed in the English localization. Only the Master Ball kept its Japanese name.
** {{i|Poké Ball}} (Japanese: モンスターボール ''Monster Ball'')
** [[Great Ball]] (Japanese: スーパーボール ''Super Ball'')
** [[Ultra Ball]] (Japanese: ハイパーボール ''Hyper Ball'')
*** The Ultra Ball retains a letter H on its design, referencing its Japanese name.
** [[Master Ball]] (Japanese: マスターボール ''Master Ball'')
* The [[Potion]] and its improved variants introduced in Generation I use the Japanese word ぐすり ''Medicine'', which does not specify the type of medicine. The word "Potion" would indicate a form of liquid substance; it was introduced in the English translation. With the introduction of item sprites in {{game|FireRed and LeafGreen|s}}, these items are depicted in-game as bottles designed to spray liquid substances, which may be compatible with both the Japanese and English names. Some of these items have also been depicted in official art and {{pkmn|Trading Card Game|TCG}} cards as spray bottles since [[Generation I]] as well, including the {{OBP|Potion|Base Set 94}} and {{OBP|Super Potion|Base Set 90}} cards.
** Potion (Japanese: キズぐすり ''Wound Medicine'')
** Super Potion (Japanese: いいキズぐすり ''Good Wound Medicine'')
** Hyper Potion (Japanese: すごいキズぐすり ''Amazing Wound Medicine'')
** Max Potion (Japanese: まんたんのくすり ''Tank-Filling Medicine'')
** Full Restore (Japanese: かいふくのくすり ''Recovery Medicine'')
* The [[drink]]s introduced in Generation I had their names changed in the localization:
** [[Fresh Water]] (Japanese: おいしいみず ''Delicious Water'')
*** Its name mentions that it's "fresh" in English, but mentions that it's "delicious" in Japanese.
*** Fresh Water is collected from [[Mt. Silver]], according to the Japanese item description in [[Pokémon Gold and Silver Versions|Pokémon Gold, Silver]], [[Pokémon Crystal Version|Crystal]], and [[Pokémon Stadium (English)|Stadium]]. This is also mentioned in the Korean item description from Pokémon Gold and Silver. The reference to Mt. Silver is not found in the English item description.
** [[Soda Pop]] (Japanese: サイコソーダ ''Psycho Soda'')
*** Its name includes "Psycho" in Japanese, but "Pop" in English instead.
** [[Lemonade]] (Japanese: ミックスオレ ''Mix au Lait'')
*** The [[Lemonade]]'s Japanese name means "Mix au Lait" instead. The word "lait" means "milk" in French, which indicates that this is some form of mixture involving milk. There is no indication in the Japanese name that the drink might include lemon in any way, even though it's called "Lemonade" in English.
*** From [[Generation II]] onwards, Lemonade's Japanese item description says that it's "very sweet". This was omitted from the English item description in Generation II, but it's mentioned from [[Generation III]] onwards.
* The [[Ether]], [[Elixir]], and their improved versions have Japanese names unrelated to their English names. The Japanese names all include the word "PP" (specifically in the form of katakana "ピーピー"), and don't involve the words "Ether" or "Elixir" in any way.
** [[Ether]] (Japanese: ピーピーエイド ''PP Aid'')
** [[Max Ether]] (Japanese: ピーピーリカバー ''PP Recover'')
** [[Elixir]] (Japanese: ピーピーエイダー ''PP Aider'')
** [[Max Elixir]] (Japanese: ピーピーマックス ''PP Max'')
* The [[Repel]]'s Japanese name refers refers to insect repellents; it includes the term むし ''Insect''. The Repel and its improved variants include the word スプレ ''Spray'' in Japanese, indicating their design; however, this word is absent in the English names. Additionally, むしよけ ''Repellent'' is not found in the Japanese names of Super Repel and Max Repel. The [[Super Repel]] and [[Max Repel]] are ranked as "Silver" and "Gold" in Japanese; these words were replaced by "Super" and "Max" in English.
** [[Repel]] (Japanese: むしよけスプレー ''Repellent Spray'')
** [[Super Repel]] (Japanese: シルバースプレー ''Silver Spray'')
** [[Max Repel]]  (Japanese: ゴールドスプレー ''Gold Spray'')
* [[Poké Doll]] (Japanese: ピッピにんぎょう ''{{p|Clefairy|Pippi}} Doll'') The Japanese name indicates that it's a {{p|Clefairy}} doll. However, the English item name does not mention Clefairy.
** The species of Poké Doll has always been clear in the Japanese games since its introduction in Generation I. However, it was only revealed years later in English games, once the Clefairy doll sprite debuted in Pokémon FireRed and LeafGreen.

====Items introduced in Generation II====
* [[Secret Medicine]] (Japanese: ひでんのくすり ''Secret Medicine''). This item is a pouch of pills. Prior to [[Pokémon Brilliant Diamond and Shining Pearl]], it was known as '''Secret Potion''', like the spray-type medicines, despite not being a liquid medicine.
** Much like the [[Potion]] and its improved variants introduced in [[Generation I]], the Secret Potion includes the Japanese word くすり ''Medicine'' (which does not indicate exactly what kind of medicine), but was converted to the word "Potion" (which would indicate a form of liquid substance). When the Secret Potion debuted in [[Generation II]], items did not have in-game sprites, so its appearance had not been established yet. Secret Potion's depiction as a pouch of pills was introduced years later as the item sprite in {{game|Diamond and Pearl|s}}, but its English name remained until [[Pokémon Brilliant Diamond and Shining Pearl]].
** However, in the anime episode ''[[EP209|Machoke, Machoke Man!]]'', Secret Medicine is depicted as a bottle of medicine, which is consistent with both the Japanese and English names. This predates the introduction of the pouch of pills sprite.
* [[Rainbow Wing]] and [[Silver Wing]] are single feathers in Japanese, but their English names changed to wings instead. In particular, there is no indication in the English [[Generation II]] games that these items were originally supposed to be feathers, because these games don't have item sprites. Their item sprites (depicting them as single feathers) debuted in the [[Generation IV]] remakes, but their names remained as before, with the word "Wing".
** [[Rainbow Wing]] (Japanese: {{tt|虹色の羽根|にじいろのはね}} ''Rainbow Feather'')
** [[Silver Wing]] (Japanese: ぎんいろのはね ''Silver Feather'')

====Items introduced in Generation III====
* The five [[contest condition|condition]]-related [[Scarf|Scarves]] are Bandannas in Japanese. The English name "Scarf" implies they are worn around the neck, but the Japanese name "Bandanna" implies they are worn at the top of the head.
** [[Blue Scarf]] (Japanese: あおいバンダナ ''Blue Bandanna'')
** [[Green Scarf]] (Japanese: みどりのバンダナ ''Green Bandanna'')
** [[Pink Scarf]] (Japanese: ピンクのバンダナ ''Pink Bandanna'')
** [[Red Scarf]]  (Japanese: あかいバンダナ ''Red Bandanna'')
** [[Yellow Scarf]] (Japanese: きいろのバンダナ ''Yellow Bandanna'')
* [[Fluffy Tail]]  (Japanese: エネコのシッポ ''{{p|Skitty|Eneco}}'s Tail''). The Japanese name indicates that it's a {{p|Skitty}}'s tail. However, the English item name does not mention Skitty.
** In particular, the species of Fluffy Tail is not revealed in the English version of {{game|Ruby and Sapphire|s}}, because this game doesn't have item sprites. The item sprite depicting a Skitty's tail debuted in Pokémon FireRed and LeafGreen (however, this item is unavailable in this game outside of trades).

====Items introduced in Generation IV====
* The three [[evolution stone]]s introduced in this generation have different names in English and Japanese, although their meanings are related to some extent.
** [[Shiny Stone]] (Japanese: ひかりのいし ''Light Stone'')
** [[Dusk Stone]] (Japanese: やみのいし ''Darkness Stone'')
** [[Dawn Stone]] (Japanese: めざめいし ''Awakening Stone'')
* [[Lunar Feather]] (Japanese: みかづきのはね ''Crescent Moon Feather''). Much like the [[Generation II]] items [[Rainbow Wing]] and [[Silver Wing]], this item is a single feather in Japanese, but is named "Wing" in English from [[Generation IV]] to [[Pokémon Sword and Shield]]. Additionally, the Japanese name is exactly about the crescent moon, while the English name simply references the moon. It was renamed to '''Lunar Feather''' in [[Pokémon Brilliant Diamond and Shining Pearl]], more closely reflecting its Japanese name.

====Items introduced in Generation V====
* [[Pretty Feather]] (Japanese: きれいなハネ ''Beautiful Feather''). This item is a single feather in Japanese, but is named "Pretty Wing" from [[Generation V]] to [[Generation VII|VII]]. It was renamed to "Pretty Feather" in [[Generation VIII]], which is closer to the Japanese name. This is similar to some earlier Japanese feathers that were converted to wings in the English translation: the [[Generation II]] items [[Rainbow Wing]] and [[Silver Wing]], and the [[Generation IV]] item [[Lunar Feather|Lunar Wing]].

====Items introduced in Generation VII====
* The [[Bottle Cap]]'s Japanese name includes the fact that it's silver. This is similar to the [[Gold Bottle Cap]], which kept the reference to gold in English.
** [[Bottle Cap]] (Japanese: ぎんのおうかん ''Silver Bottle Cap'')
** [[Gold Bottle Cap]] (Japanese: きんのおうかん ''Gold Bottle Cap'')
* [[Beast Ball]] (Japanese: ウルトラボール ''Ultra Ball''). Both the Japanese and English names reference the fact that it was developed to catch [[Ultra Beast]]s. Its name changed in the English localization because the Japanese name was already taken by another Poké Ball variant introduced in [[Generation I]], the [[Ultra Ball]].
* The [[Lure]]'s Japanese name is similar to repel, but むしよけ ''Repellent'' is replaced by むしよせ ''Attractant''; both terms involve むし ''Insect''. The Lure and its improved variants include the word コロン ''Cologne'' in Japanese, indicating their design; however, this word is absent in the English names, being replaced by "Lure". Additionally, むしよせ ''Attractant'' is not found in the Japanese names of Super Lure and Max Lure. Much like the Repel variants, the [[Super Lure]] and [[Max Lure]] are ranked as "Silver" and "Gold" in Japanese; these words were replaced by "Super" and "Max" in English.
** [[Lure]] (Japanese: むしよせコロン ''Attractant Cologne'')
** [[Super Lure]] (Japanese: シルバーコロン ''Silver Cologne'')
** [[Max Lure]] (Japanese: ゴールドコロン ''Gold Cologne'')

====Items introduced in Generation VIII====
* All the seven [[Sweet]]s that cause {{p|Milcery}} to evolve into {{p|Alcremie}} are  {{wp|amezaiku}} (a form of Japanese candy craft artistry) according to their Japanese names.
** [[Strawberry Sweet]] (Japanese: いちごアメざいく ''Strawberry Amezaiku'')
** [[Love Sweet]] (Japanese: ハートアメざいく ''Heart Amezaiku'')
*** The word "Heart" found in the Japanese item name is a more literal description of its shape, while "Love" is an abstract concept.
** [[Berry Sweet]] (Japanese: ベリーアメざいく ''Berry Amezaiku'')
** [[Clover Sweet]] (Japanese: よつばアメざいく ''Four-Leaf Amezaiku'')
** [[Flower Sweet]] (Japanese: おはなアメざいく ''Flower Amezaiku'')
** [[Star Sweet]]  (Japanese: スターアメざいく ''Star Amezaiku'')
** [[Ribbon Sweet]] (Japanese: リボンアメざいく ''Ribbon Amezaiku'')

==In the core series==
{{incomplete|section|Add more regional differences}}

* In all [[core series]] games, the player writes a report (Japanese: レポート ''report'') when saving the game. This "report" option is found at the Japanese version [[main menu]]. The references to writing a report were simply translated as saving the game.
* The units of measurement used for the Pokémon's [[List of Pokémon by height|height]] and [[List of Pokémon by weight|weight]] (as seen in the [[Pokédex]]) depend on the game language.
** Japanese games: height in meters, weight in kilograms
** American games: height in feet and inches, weight in pounds
* In the [[core series]], from [[Generation II]] onwards (as well as all games in the [[Pokémon Stadium series]] since [[Generation I]]), the [[Pokédex]] is able to sort Pokémon by their {{wp|katakana}} name in the Japanese version, or alphabetically in the localized versions.
* Some Pokémon games have multiple optional names for the [[player character]] and/or [[rival]]. These names are often different on each language version. For instance, a character may have different optional names in Japanese, English, French, German, Italian, Spanish, and Korean.
** The player characters with optional names in the [[core series]] are: {{ga|Red}}, {{ga|Leaf}}, {{ga|Ethan}}, {{ga|Kris}}, {{ga|Lyra}}, {{ga|Brendan}}, {{ga|May}}, {{ga|Lucas}}, and {{ga|Dawn}}.
** The rivals with optional names in the core series are: {{ga|Blue}} and {{ga|Barry}}

===Generation I===
====Pokémon Red, Blue, and Yellow====
* The first pair of games in Japan was {{game|Red and Green|s}}, followed by [[Pokémon Blue Version (Japanese)|Blue]] as the third [[core series]] game, which included a graphics and sound upgrade, as well as the removal of several known glitches that had been found in the original pair. In the localizations, the first pair of games was {{game|Red and Blue|s}}, which had the same [[game-exclusive Pokémon]] available as Pokémon Red and Green, and also kept the improvements from the Japanese Pokémon Blue.
* The English and other international versions of {{game|Yellow}} are colorized when played on either the [[Game Boy Color]] or the [[Virtual Console]]. However, the Japanese version of this game is black and white in both game systems.
** For comparison, the earlier games {{game|Red and Blue|s}} are black and white in both Game Boy Color and Virtual Console as well, while all the [[Generation I]] [[core series]] games can be played with color on the [[Super Game Boy]] (an accessory released for the [[Super Nintendo Entertainment System|SNES]]), regardless of their language.
* In the Japanese version, the Kanto [[Badge]]s are named after colors. In the English version, most Kanto Badges were renamed. For instance, "グレーバッジ" (Gray Badge) was translated as "Boulder Badge". The only Kanto Badge that kept its Japanese name in the English Localization (only written with English letters instead of Japanese katakana) was [[Erika]]'s Rainbow Badge.
* In the Japanese version, the Pokémon's [[level]] is repeated in the first and second [[summary|stats]] screens. In other language versions, the level is only shown in the first screen.
* In the [[player's house|player's bedroom]], the video game console depends on the game and language:
** Famicom (in the Japanese version of all [[Generation I]] games, except for Pokémon Yellow)
** Super Famicom (in the Japanese version of {{game|Yellow}})
** [[Super Nintendo Entertainment System|SNES]] (in the international versions of all Generation I games)
* The film on TV at the player's living room depends on the game's language.
** In all languages except French, a movie involving four boys walking on railroad tracks, possibly a reference to ''{{wp|Stand by Me (film)|Stand by Me}}''.
** In the French version of the Generation I games, an animated cartoon featuring a boy with a monkey tail (French: "Un dessin animé! Un petit garçon avec une queue de singe."), possibly a reference to young Son Goku from ''{{wp|Dragon Ball}}'', or alternatively, young Son Gohan from the sequel ''{{wp|Dragon Ball Z}}''.
* In the Japanese version, the [[Town Map]] has a border around the map, and the place name is displayed on a short blank space at the top-left corner outside that border. In the international versions, that border was removed, and the place name is displayed on a blank line above the map, leaving more space for longer place names.
* In the Japanese version, the [[Kanto]] region is mentioned if the player interacts with the [[Town Map]] in [[Daisy Oak|Daisy]]'s house (if the map has not been obtained yet). However, Kanto is not mentioned in the international versions.
** This is the only in-game mention of the Kanto region in the Japanese version of these games. Therefore, Kanto is not mentioned at all in the international versions.
[[File:YellowTitle GBC unused.png|thumb|The Game Boy Color mode's yellow palette]]
* In Japanese Yellow on [[Game Boy Color]] mode, the game uses a yellow palette similarly to how Red, Green, and Blue use their respective red, green, and blue palettes. In Western Yellow, Game Boy Color mode instead uses the [[Super Game Boy]] palettes but with more saturated colors. The yellow palette from Japanese Yellow is used by Western Yellow in certain situations like [[Pikachu's Beach]] hi-score screen and it can be reinstated completely by modifying the ROM
* In the Japanese version of all Kanto-based games, the {{ka|old man}} passed out drunk at the start of the game, hence why he blocks the way out of [[Viridian City]] at the start of the game. In the English version, he is grumpy due to not having had his coffee yet.
* Because Pokémon Red and Blue's script is based on a translation of the script of {{game|Blue| (Japanese)}} but use the [[in-game trade]]s from {{game|Red and Green|s}}, two translation errors related to these trades occur.
** The man who trades the {{player}} an {{p|Electrode}} on [[Cinnabar Island]] claims that the {{p|Raichu}} he received "went and [[Evolution|evolved]]". As Raichu does not have an evolved form, this is not possible. In the context of Japanese Pokémon Blue, it makes sense as the player trades away a {{p|Kadabra}}, which evolves through trade, for a {{p|Graveler}}.
** The old man who trades the player a {{p|Jynx}} in [[Cerulean City]] claims that the {{p|Poliwhirl}} he received "went and evolved". As Poliwhirl cannot evolve via [[trade]] in [[Generation I]], this is not possible. In the context of Japanese Pokémon Blue, the old man trades away a {{p|Haunter}} for a {{p|Machoke}}, which does evolve through trade.
* When encountering a Pokémon using a fishing rod, the game says ''"The hooked <POKÈMON> attacked!"'' In the Spanish localization, this was erroneously translated to ''"¡El malvado <POKéMON> atacó!"''. The word ''"malvado"'' translates roughly to "wicked" or "evil."
* The acronym for TM in the French localization of the games is CT. It is used incorrectly in one area of the game. When the player exchanged [[Lemonade]] for [[TM49|CT49]], the text reads ''"TM49... TRIPLATTAQUE!"''.
* In the Spanish and Italian localizations of the games, both versions erroneously refer to Squirtle's shell as ''"concha"'' and ''"conchiglia"'' which translates to "seashell" in Spanish and Italian respectively.
* In the Japanese versions of Generation I games (as well as in all versions of Generation II games and [[Pokémon Stadium series]] games), the moves {{m|Absorb}}, {{m|Mega Drain}}, {{m|Leech Life}}, and {{m|Dream Eater}} always fail if the target is behind a {{m|Substitute}}. In the localized versions of Generation I games, these moves always hit{{tt|*|Dream Eater hits if the target is sleeping}} if the target is behind a Substitute.<ref>[https://web.archive.org/web/20200802034320/https://forums.glitchcity.info/index.php?topic=7522.0 Swift (Speed Star) in Japanese 1st Gen - Glitch City Laboratories Forums]</ref><ref>[https://pastebin.com/nJzRK337 Pokemon Red substitute/swift/drain bugs - Pastebin]</ref>
** Both the original effect (always miss behind a Substitute) and the localized Generation I effect (always hit behind a Substitute) were likely mistakes in the game code. The localized "always hit" effect was likely introduced when fixing the glitch that caused {{m|Swift}} to always hit a target behind a Substitute in Japanese games (even if the target is in the [[semi-invulnerable turn]] of {{m|Fly}} or {{m|Dig}}).
* In the Japanese Pokémon Red and Green, {{p|Nidoqueen}}'s weight is listed as 6.0 kg. This was corrected in the Japanese Pokémon Blue to 60.0 kg. {{p|Geodude}} is also affected as its weight in the Japanese Pokémon Red and Green is listed as 2.0 kg, this was also corrected in the Japanese Pokémon Blue to 20.0 kg.
* In the Japanese version, there are [[wikipedia:Butsudan|butsudan]] (Buddhist shrines) in some Celadon City buildings, but they were changed to sculptures of {{p|Diglett}} in the English version. They return the text "ぶつだん だ……" (It's a butsudan...) in Japanese, but "It's a sculpture of DIGLETT." in English. 
* In the Japanese version of all Kanto-based games, the characters Erik (Japanese: コージ ''Kōji'') and Sara (Japanese: アツコ ''Atsuko'') may be cameos of [[Kōji Nishino]] and [[Atsuko Nishida]]. They failed to meet each other due to a misunderstanding on the word "とり" (tori), which is also a pun. Erik used a bird Pokémon to arrive at [[Fuchsia City]] ("tori Pokémon" means "bird Pokémon"), while Sara is waiting for him inside the {{safari|Kanto}}{{sup/1|RBY}}{{sup/1|FRLG}}/[[GO Park]]{{sup/7|PE}} ("Pokémon tori" means "obtain Pokémon"). This pun was lost in the English localizations. Additionally, in the English version of the Generation I and III games, Sara says that Erik is her boyfriend (which is not the case in the Japanese version of all games, and is also not said in the English version of the Generation VII games).

* The Japanese version of the [[Pokémon Mansion journals]] use a singular "わたし" (watashi, "I" pronoun), implying that only one person was involved in discovering {{p|Mew}} and creating {{p|Mewtwo}}. The English localization changed this pronoun to "we"; this happens to be consistent with the events of [[M01|Pokémon: The First Movie - Mewtwo Strikes Back]], in which a group of scientists created Mewtwo.
* The [[Cerulean Cave]] has a different layout in the Japanese {{game|Red and Green|s}} and international {{game|Red and Blue|s}} (in addition to further layout changes in {{game|HeartGold and SoulSilver|s}}).
* In the Japanese versions, the [[PC storage system]]  has 8 boxes with 30 Pokémon each instead of 12 boxes with 20 Pokémon each.
* In the Japanese versions of the handheld games, {{m|Blizzard}} has 30% chance to freeze. The chance was lowered to 10% for {{game|Yellow}}'s [[Pokémon Yellow Version#Connectivity|Colosseum 2]], the [[Pokémon Stadium series|Stadium games]], and all international Generation I games.
* In the Japanese versions of the Generation I handheld games, {{m|Swift}} functions as a 100% accuracy move due to [[List of glitches (Generation I)#Swift effect glitch|a glitch]], unless the opponent is behind a {{m|substitute}}. In all international games, Swift bypasses {{stat|accuracy}} checks to always hit.
* In the Western language releases of Pokémon Yellow on the [[Virtual Console]], which are emulated in [[Game Boy Color]] mode, {{p|Jynx}}'s battle sprites have been recolored to align with its modern design, recoloring Jynx's black skin to purple. Jynx's original design had previously been subject to {{pkmn|controversy}} due to its resemblance to racial stereotypes of African-Americans. The Japanese release is emulated in [[Game Boy]] mode—which is monochromatic—so no change was made.
* In the localized versions of Generation I games, a {{tc|Bird Keeper}} in {{rt|14|Kanto}} states that the Legendary birds are birds of prey. In the original Japanese dialogue, he simply says that they are three birds.

===Generation II===
====Pokémon Gold, Silver, and Crystal====
* In the Japanese and Korean versions, the [[summary|stats]] and [[trade]] screens are vertically divided in two parts; in all other languages, they are divided horizontally.
* In the Japanese and Korean versions, the {{OBP|Pokémon|species}} in the [[Pokémon Storage System]]'s layout is enclosed in a text-box frame and the Pokémon list appears in the background. In the Western localizations, there is no frame surrounding the Pokémon but the Pokémon list appears in a text-box frame.
* In the Japanese and Korean versions, the sign of [[Pokémon Center]]s in [[Johto]] have a {{i|Poké Ball}} drawing with the letters '''PC''' next to it. In the Western localizations, the sign was changed back to the one used in the [[Generation I]] games. The Pokémon Center signs in [[Kanto]] use the old design in all versions.
* In the Japanese and Korean versions, {{m|Sonic Boom|SonicBoom}}'s animation is a shock wave hitting the opponent. In the Western localizations, Sonic Boom uses the {{m|Gust}} animation (a tornado hitting the opponent).
* In the Japanese version, the [[wikipedia:Butsudan|butsudan]] (Buddhist shrines) return in some Celadon City buildings, and now there are butsudan in [[Violet City]], [[Azalea Town]], [[Ecruteak City]], [[Mahogany Town]], and the [[Mt. Moon Square|Mt. Moon Gift Shop]] as well. This time, they return the text "ぶつだん だ…… うーん おせんこうの におい" (It's a butsudan... Hmm, the smell of incense.) in Japanese and "What is this? Oh, it's an incense burner!" in English.
** [[Kurt]]'s house has butsudan with a different text, mentioning the "god" (kami-sama) of the forest, which was changed to "protector" in the localization; in either case, this is a reference to {{p|Celebi}}. This butsudan returns "もりのかみさまを まつってある" (This is to worship the god of the forest.) in Japanese and "It's a statue of the forest's protector." in English. In the [[Generation IV]] remakes, this shrine remains in Kurt's house, but the player cannot interact with it.
* In the Japanese and Korean versions, {{tc|Pokéfan}} Alex in {{rt|13|Kanto}} has three Pokémon with "king" in their names: {{p|Nidoking}}, {{p|Slowking}}, and {{p|Magikarp}} (Koiking). In the localized versions, Magikarp was changed to {{p|Seaking}} to keep this theme. However, this change was not replicated in the [[Generation IV]] remakes, in which Magikarp is kept in all versions.
* [[Miracle Cycle]] is not named in the localized versions.
* In the Japanese version, the [[PC storage system]]  has 9 boxes with 30 Pokémon each instead of 14 boxes with 20 Pokémon each.
* The Japanese [[Super Game Boy]] border of Pokémon Gold (labeled '''POCKET MONSTERS GOLD VERSION'''), but not of Pokémon Silver, is present but unused in all releases of {{game|Crystal}}. Similarly, in the Korean releases of Gold and Silver, the English Super Game Boy borders (respectively labeled '''POKéMON GOLD VERSION''' and '''POKéMON SILVER VERSION''') are present but unused, since they only support the [[Game Boy Color]].
* In the Korean versions, the [[credits]] are presented in English. The Japanese games would later replicate this in [[Generation V]] but only when {{DL|Options|character mode}} is set to {{wp|kanji}}.
* Due to a possible oversight in the international versions, the Japanese quotation marks are used in certain parts of the dialogue, like in radio stations. This was corrected in Crystal.
* During battles in Pokémon Crystal, Japanese midline horizontal ellipses ("⋯") are used in the English versions instead of regular ellipses ("&hellip;") due to an oversight.
* As the [[Mobile Game Boy Adapter]] was not released outside of Japan, all related features were removed in localized versions of {{game|Crystal}}, with the exception of the [[Odd Egg]]. The Virtual Console release finally allowed international players to have a chance to receive the [[GS Ball]] after entering the [[Hall of Fame]].
* In the Japanese version of Pokémon Crystal, a researcher at the Ruins of Alph claims that the [[Pokémon Communication Center]] in [[Goldenrod City]] influences the Unown. His unused English text is: ''According to my research... Those mysterious patterns appeared when the <sc>Pok</sc>é<sc>com Center</sc> was built. It must mean that radio waves have some sort of a link...''
* Pokémon Crystal version is the last localized [[core series]] game to use the slogan ''[[Gotta catch 'em all!]]''.
* The Japanese version of Pokémon Crystal has an emblem of Suicune's crest on the back of the Game Pak's circuit board.
* In the Western releases, un-nicknamed Nidoran has the gender symbol shown twice, once by the name and once by the level indicator. This is not case in the Japanese and Korean versions, where all Pokémon have the gender symbol placed after their name, rather than by the level indicator.
* Pokémon Gold and Silver can be played either on the [[Game Boy]] or the [[Game Boy Color]] in all languages except Korean. However, the Korean version of these games is only compatible with the Game Boy Color.
* In the Japanese and Korean versions, {{p|Phanpy}} and {{p|Donphan}} are found in the {{pkmn2|wild}} in Pokémon Gold while {{p|Teddiursa}} and {{p|Ursaring}} are found in the wild in Pokémon Silver. In the Western localizations, these were switched. This change was not replicated in the international versions of {{game|HeartGold and SoulSilver|s}}.
* The Korean versions of the games can only be played on the [[Game Boy Color]], due to the need for more memory in order to properly render the Korean characters.
* Nineteen {{OBP|Pokémon|species}}, including {{p|Jynx}}, as well as five {{pkmn|Trainer}}s, had their sprites changed between the Japanese and Western versions. The Korean versions use the same sprites as the Japanese versions. The changes made for Western versions were also taken into account for the Japanese and Western versions of {{game|Crystal}}, although they were instead incorporated in the new sprites.

===Generation III===

* A portion of the fourth room in Trick House in {{g|Emerald}} has been altered in international versions, to make it harder for player to trap themselves and be forced to start the puzzle from the beginning.
* Several glitches were fixed in the international releases.
* The VU Meter in the [[Pokédex]] was altered depending on which international version was being played.
* ''Pokémon Battle-e'' Trainer cards request screen was changed in international releases.

====Pokémon FireRed and LeafGreen====
* In the original Japanese version, the blue and pink font color is used only for the Continue button on title screen, with NPC's gender changing the font style instead.
* On the title screens, the Japanese versions say ''PRESS START BUTTON'' while international releases just say ''PRESS START''.
* The name entry screen in Japanese versions only allows for five characters in a name, the international releases changed the character limit from five to seven.
* In the [[player's house|player's bedroom]], the Japanese version contains a Famicon, while international releases contain a NES instead.
* The film on TV at the player's living room depends on the player's gender and game's language.
** In all languages except French:
*** If the player is male, a movie involving four boys walking on railroad tracks, possibly a reference to ''{{wp|Stand by Me (film)|Stand by Me}}''.
*** If the player is female, a movie featuring a girl in pigtails walking down a brick road, possibly a reference to ''{{wp|The Wizard of Oz (1939 film)|The Wizard of Oz}}''.
** In French:
*** If the player is male, a movie featuring a "cool guy in a taxi" (French: ''"Y'a un gars cool dans un taxi."''), possibly a reference to the 1998 French movie ''{{wp|Taxi}}''.
*** If the player is female, ''{{wp|The Lord of the Rings}}'' is mentioned by name.
* In international releases, the Lv icon on battle screens was moved to the right corner and the level number was made normal instead of bold. ''♂'' and ''♀'' symbols were also given a slight alteration.
* Poké Center and Poké Mart signs were altered between regional releases.
* In [[Trainer Tower]], the international releases had e-Reader battle card compatibilities removed as those cards were never released outside of Japan due to the poor sales of the e-Reader in the US.
* In European versions of the Pokémon Firered and LeafGreen, the Nugget Bridge Rocket Grunt glitch was patched. This prevents the player from getting unlimited Nuggets.
* If one presses '''↑ + SELECT + B''' on the title screen to delete all [[save]] data, in the Japanese versions, the screen is teal in FireRed and blue in LeafGreen. In the localizations, the screen in both versions is bright green.

===Generation IV===
====Pokémon Diamond, Pearl, and Platinum====
* In the Japanese version of the [[Sinnoh myths]], the Sinnoh Folk Story 3 refers to Pokémon and people marrying each other. In the English version, the marriage is not mentioned; instead, it says Pokémon and people would eat together at the same table.
* In the Japanese version of Pokémon Platinum, a glitch can occur on Route 225 where the player is stuck in a loop of battling Ace Trainer Deanna until the Player is no longer able to battle. This was fixed in the international version.
* The dialogue at the [[Veilstone Game Corner]] was altered in the European and Korean versions of Pokémon Platinum to comply with PEGI's then new standards regarding gambling in video games.
* In the non-English European versions of {{game|Diamond and Pearl|s}}, Registeel's sprite was edited because of its arm. The arm's original position is reminiscent of the {{wp|Nazi}} {{wp|Nazi salute|salute}}. This change was retained in all releases of {{game|Platinum}} and {{game|HeartGold and SoulSilver|s}}.

* In the Korean versions of Pokémon HeartGold and SoulSilver, Sage's sprite was altered to remove the prayer beads in his hands and gave him a sash.

===Generation V===
* In all Generation V core games, Pokémon such as {{p|Cofagrigus}}, {{p|Froslass}}, {{p|Nosepass}}, and {{p|Probopass}} that originate from English-language games cannot be traded through the [[GTS]] unless they are given a nickname due to the word filter in the games. This was fixed from Generation VI onwards so that they did not need a name change to be traded.

====Pokémon Black and White====
* The Online Battle name differs between regions.
* The chance that {{a|Poison Touch}} will poison the target was changed from 20% to 30% in international versions.
* The symbol used in the move {{m|Imprison}} was changed in the international versions.
* The amount of C-Gear skins distributed differed between regions; Japanese versions had 31 skins, North American versions had 22 skins, and European versions had 25 skins.
* As {{p|Victini}} is a Shiny Locked Pokémon, its shiny form can never be obtained. In Japanese versions if the game generated a value that would cause Victini to be shiny, the battle would never begin, this was fixed in international versions.

====Pokémon Black 2 and White 2====
* The lyrics for the [[Virbank Gym]] music differ between the Japanese and international releases. In Japanese versions, she spells out "''{{p|Koffing|Dogars}}"'' which is Koffing's Japanese name. In the international versions she spells out "''Pokémon"'' and does not start the song by saying "''1, 2, 3, 4!"''
* After entering the Hall of Fame, there is a post-game story section where the player follows N's Zoroark to N's Castle. In Japanese versions, if the player exits out of the cave that Zoroark just went into instead of following them, it causes the game to softlock. This was fixed in international versions.

==In the side series==
===Pokémon Stadium series===
* In Japan, there were three games in the [[Pokémon Stadium series]].
** {{jap|Pokémon Stadium}} (Japanese: ポケモンスタジアム ''Pokémon Stadium''), with only 42 [[Generation I]] Pokémon available. This game was not released in English.
** {{eng|Pokémon Stadium}} (Japanese: ポケモンスタジアム２ ''Pokémon Stadium 2''), with the Generation I Pokémon available. This was the first game of the series released in English.
** [[Pokémon Stadium 2]] (Japanese: ポケモンスタジアム 金銀 ''Pokémon Stadium Gold and Silver''), with the [[Generation I]] and [[Generation II|II]] Pokémon available. This was the second game of the series released in English.
* The player may connect up to four [[core series]] games to any of the three Pokémon Stadium games using the [[Transfer Pak]] ([[Generation I]] core series games are compatible with all three Stadium games; [[Generation II]] core series games are only compatible with [[Pokémon Stadium 2]]). However, the compatibility also depends on the language of the games.
** The American and European versions are compatible with each other. For instance, the player may connect the French version of Pokémon Stadium to the German version of Pokémon Red.
** The Japanese games in the Pokémon Stadium series are only compatible with Japanese core series games.
** The Korean versions of {{game|Gold and Silver|s}} are not compatible with any game in the Pokémon Stadium series.
* The {{p|Pikachu}}'s voice heard upon launch was instead people's voices in the Japanese version.

===={{eng|Pokémon Stadium}}====
* The Japanese version has six Stadium Cups. In addition to the Pika, Petit, and Prime Cups, there are three cups based upon [[Rule variants#Japanese tournaments|official tournaments]]: the [[Rule variants#Pokémon Stadium|Nintendo Cup '97, Nintendo Cup '98, and Nintendo Cup '99]]. In the international versions, the Nintendo Cups were replaced with the Poké Cup from Pokémon Yellow's Colosseum 2.
* Several [[rental Pokémon]] had their movesets changed between the Japanese and localized versions.
* A gallery mode was added, but only in the American version (it is absent in Japanese and European versions).
** In the Japanese and European versions, the [[main menu]] has the "[[options]]" button in the middle, below the "Pokémon Stadium" option. In the American version, the "gallery" button was added where the "options" would be in other games, and the "options" button was moved to the right side.
* {{p|Pikachu}} can be taught {{m|Surf}} under special conditions. Japanese players could teach a Pikachu Surf in the [[Pokémon Stadium (Japanese)#Special Pokémon|original Pokémon Stadium]].
* The number of teams that could be registered was decreased from 12 to 10.
* In Clefairy Says, the Clefairy sing rather than repeat the same sound effect.

===Pokémon Colosseum===
* In Europe, a GameCube Bundle could be purchased which included Pokémon Colosseum, a memory card, [[Pokémon Box Ruby & Sapphire]] as a bonus disc, and a [[GameCube]]-[[Game Boy Advance]] [[Game Link Cable]].
* In the international localizations of {{g|Colosseum}}, [[Rui]]'s shirt and skirt were lengthened.
* Due to the [[Phenac City#Pokémon Center|e-Reader room]] being dummied out in the international releases, three more Shadow Pokémon are not normally obtainable. Encounters with the Trainers that would have had {{p|Mareep}}, {{p|Togepi}}, and {{p|Scizor}} are not possible in the international releases without hacking the game.

==In spin-off games==
===Pokémon Trading Card Game===
* Booster pack images were changed between localizations to reflect the art style used for booster packs by region.
* The title screen was changed between the Japanese and international releases.
* The [[Super Game Boy]] border in international releases removes the writing of ''Pokémon • Trading • Card • Game •'' on the Poké Balls.
* The back of Pokémon cards was changed in international releases to the design used on the back of cards outside of Japan.
* In the Japanese version, the symbol for a {{DL|Special Conditions (TCG)|paralyzed}} Pokémon are two vertical jagged lines ([[File:TCG GB paralyzed JP.png]]). In the American and European versions, the symbol is a horizontal jagged line ([[File:TCG GB paralyzed INT.png]]).
* The artwork for [[Jynx (Base Set 31)|Jynx Lv. 23]]'s face was changed from black to purple in international releases to avoid further [[Jynx (Pokémon)#Controversy|controversy]]. The background of the card was also changed from dark purple to light purple in the [[Virtual Console]] release.
* When the player tries to save an unnamed {{OBP|deck|GB}} in the Japanese version, the player name is included in the default deck name. In all other languages, the player name is not included. For instance, if the player is named "パーク" ({{TCG GB|Mark|Park}}) in the Japanese version, the first default name used for an unnamed deck is "パークの００１デッキ" (Park's 001 Deck). In the English version, the first default name is simply "001 Deck"
* In the Japanese version of {{ga|Pokémon Trading Card Game}}, [[Imakuni?]] says that he sings the [[Can You Name All the Pokémon?]], which is a true statement in real life. However, in the English localization, Imakuni? mentions that he sings the [[Pokérap]] instead. Both [[Can You Name All the Pokémon?]] and the [[Kanto Pokérap]] are songs listing the [[Generation I]] Pokémon.

===Hey You, Pikachu!===
* Certain items have been changed:
** The [[rice ball]] (an item that Pikachu can eat) was changed to a cupcake.
** In Japanese version, the corn in garden is eggplants instead. Due to this, popcorn is not present in these versions.
** In Viridan Forest, the player finds {{wp|Typha|cattails}} instead of {{wp|Equisetum|horsetails}}.
** In Springleaf Field, the Morning glory flower is recolored to resemble a Bluebell instead.
* In the US release, the shoes outside the player's room are missing. In Japan, it is customary to take off shoes before walking into a building or home. In the US it is common to walk into buildings or homes with shoes still on. 
* The Pokémon cries have been changed to localized ones.
* In the English release, when the player is speaking, a bubble is shown to indicate that the player's voice is being detected by the microphone. In the Japanese release, the bubble only appears if the player is directly addressing Pikachu. 
* The {{wp|Suikawari}} minigame in Cobalt Coast was changed to a piñata smashing game. When Pikachu loses in the Japanese version, he receives a soda can pull tab, in the English version he receives a bottle cap ring instead.
* The Nintendo 64 in the Japanese version contains a [[Super Nintendo]] game, this was fixed in the English release to be a Nintendo 64 game instead.

===Pokémon Channel===
* The language that plays in the '''Pichu Brothers''' channel changes depending on the regional version of the game.

===Pokémon Pinball===
* The European release features a menu when starting up the game that lets the player select which language they want to play the game in.
* On the Copyright screen in the English and European versions, the games list '''Creatures Inc.''' and '''HAL Laboratory, Inc.''' instead of '''Creatures''' and '''HAL Laboratory'''. The European release was further edited to show it was released later than the Japanese and English releases.
* On the Title screen, {{p|Pikachu}} is smiling in the international releases. The European release corrects ''Poké Dex'' to POKéDEX''.
* The European release gives two options for how strong the Rumble feature is in the Options menu with the options of ''Mild'' and ''Strong''. The English and Japanese releases only have an ''Off'' and ''On'' setting. Additionally, the M in '''RUMBLE''' is slightly wider in the European release.
* The control scheme options were simplified to three predefined options in the European release.
* The [[Super Game Boy]] border is different between releases. The Japanese release lacks a ("TM") symbol. The European release features a large vibrant blue font of ''Pokémon Pinball''.
* The four lights in the out lanes and return lanes spell out CAVE in the international release and HOLE in the Japanese release.
* The Japanese version of the game spells out "GET" instead of "CATCH!" while capturing a Pokémon.

===Pokémon Puzzle League===
* The hidden developer love message depends on if the game is the Japanese or international version.

===Pokémon Mystery Dungeon: Red Rescue Team and Blue Rescue Team===
* In Japanese and Korean versions of the game, the recruit list has species name alongside the nickname. In the localization, only the nickname (if any) is displayed.
* The Japanese version of Pokémon Mystery Dungeon: Blue Rescue Team had a game breaking bug which would erase all the save data of any game in the Gameboy Advance slot. This bug was fixed in international releases.

===Pokémon Mystery Dungeon: Gates to Infinity===
* When first meeting {{p|Swanna}} in the English version of the game, she makes a statement that references {{wp|Carly Rae Jepsen}}'s song, "{{wp|Call Me Maybe}}".
* In the Japanese version, players are able to select the gender for their partner Pokémon. In the international versions, there is no gender selection.
** Because of the lack of gender selection and the fact that some languages have no gender-neutral pronoun, these languages use male pronouns.
