This friendly city started as a place where people and Pokémon gathered, then grew into a center of commerce. If you care about the looks of your Pokémon, head for the Contest Hall. For toughness, go to the Gym. The entrance to Amity Square is here. The square is a place where Trainers can stroll peacefully with Pokémon. There is a building here that is symbolic of the city's status as a place where different cultures meet. A nice fountain with benches, as well as the Pokémon Fan Club, are among the city's amenities.
Hearthome City is a child-friendly city; there are many families and young mothers living there, some of whom can be seen with prams. Most of the buildings use elevators instead of stairs so that small children and Pokémon can move through the houses. The citizens scrupulously keep their city clean.
In Platinum, the road paving was given an update so it is now all beige. The tree's sprites were changed to match those in Platinum's Eterna Forest. In addition, the appearance of the entrances to Amity Square was modified so that the arch features a Psyduck, a Torchic and a Drifloon, and a Pikachu on its back.
The biggest attraction, garnering contestants from all throughout the region, is the Super Contest Hall. The Super Contest Hall is an expanded format of the Pokémon Contests within Hoenn. In it, Pokémon are rated on their appearance and performance, rather than strength. They are different from the previous generation's competitions in that not only do they have more rounds, but rounds from the earlier games have been altered. The city's Gym Leader, Fantina, is a self-proclaimed master at Pokémon Super Contests.
A notable attraction is Amity Square, where Trainers relax with their Pokémon. Eleven different types of cute Pokémon will follow the player about in Amity Square, and many Pokémon wander about the city outside of their Poké Balls. Amity Square is located north of Hearthome City. The setup in Amity Square is identical to the Pikachu interaction system that was in Pokémon Yellow. Only certain small Pokémon can be taken for walks in Amity Square, usually of a "cute" appearance. Pokémon will fetch Accessories or Berries for their owners every 200 steps. In Pokémon Platinum, more Pokémon are allowed in than before, and the area has been expanded and redesigned. It now includes a rather large pool of water.
The Sinnoh's Pokémon Fan Club is located in the eastern area of Hearthome City. The Fan Club is basically a place for people to meet and chat about their favorite Pokémon and to show off their collections to each other. In general, the members are usually more oriented to unevolved, cute Pokémon and Pokémon Contests than Pokémon battles. The Sinnoh Pokémon Fan Club Chairman says that his Fan Club is number one nationwide because he brags more than anyone. However, he doesn't do it anymore because of people's complaints. This may also explain why only two other members are found in his club. Inside the Pokémon Fan Club, the player will receive the Poffin Case, needed to bake Poffins. Another member of the club will rate the friendship of first Pokémon in the player's party.
The Poffin House is also here, where coordinators can bake Poffins to boost their Pokémon's condition for Pokémon Super Contests, either alone or through DS Wireless Communications with people nearby. Up to four people may bake at a time. The Poffin House is located west of the Poké Mart where the player can make Poffins, which are the replacement of Pokéblocks from Ruby, Sapphire, and Emerald. The player has to speak to the lady a little to the left of the entrance, throw in his or her selected Berry and start stirring the liquid to begin creating their own Poffin. The Poffin's level depends on the amount of time consumed cooking the Poffin, the number of burns, and the number of spills.
Mr. Goods lives on the street of Hearthome, although he claims he can't remember who he is or his real name. He is a bemused man dedicated to rarities who gives out goods to decorate the Secret Base in the Sinnoh Underground with upon completion of certain tasks, such as using the GTS or defeating all eight Gyms. Mr. Goods will also reward a Trainer for other miscellaneous achievements.
The Foreign Building
The Foreign Building (Japanese: いぶんかのたてもの Foreign Culture Building) is a building located in the western side of Hearthome City. It has six benches and stained glass windows. All the people there talk about the grace of life in the Pokémon world, supernatural powers, and the balance of spirit and nature. It seems to be loosely based on a church or cathedral, and is the first building in all the Pokémon games to be so. Respectfully, no music can be heard in the building. In the morning, one can see a piece of the wall jutting out behind the stone tablets on either side of the inside.
In the middle of the city, next to the Pokémon Fan Club, is a hotel called the Pokémon Hotel. There are only two accessible floors within the hotel. These can be accessed to by a large, automatic elevator. Many visitors come from all parts of the world to enter the Super Contest, or visit Amity Square. Visitors can stay here for a while to enjoy the parts of Hearthome. The landlord inhibits the first floor, and on the second floor lives a woman and a Clefairy. She will give the player a Shell Bell, saying that she was given it on vacation, but already had one.
In Diamond and Pearl, the Gym consists of five stories, with a mathematical puzzle on each floor and three doors corresponding to a potential answer, with the correct door leading to the next floor and the wrong doors leading only to a battle with a Trainer. In Platinum, the inside of the Gym is shrouded in darkness and the player must navigate using a flashlight.
For defeating Fantina, Trainers receive the Relic Badge and TM65 (Shadow Claw). They also gain the ability to use Surf outside of battle in Diamond and Pearl, or Defog in Platinum.
Pokémon Diamond and Pearl
Hearthome City in Diamond and Pearl
In Pokémon Diamond and Pearl, the population of Hearthome City is 91 people. It is Sinnoh's largest city and one of the largest cities in the Pokémon world. Given that it is the only town in the Pokémon world to feature babies, it probably has the lowest age distribution too.
In Pokémon Platinum, the population of Hearthome City has decreased to 81 people. Despite the drop, it is still one of the largest cities in the Pokémon world.
As Zoey explained to Dawn in A Stand-Up Sit-Down!, the Hearthome City Pokémon Contest follows the Double Performance format, meaning that all Coordinators have to show off two Pokémon at once in the Performance Stage in order to advance to the second round, which consists of two-on-twoContest Battles. The event began later that day, with Jessilina also participating. For the first round, Dawn called out her Piplup and Pachirisu. Although their performance received positive reviews from allthreejudges, it was not enough to send Dawn to the Battle Stage. As a result, Dawn was eliminated from the competition while her rivals moved on to the second round. There, Nando was seen depleting all of Jessilina's points to advance to the finals, where he faced off against Zoey. He was able to defeat her with the help of his Kricketune and Roselia, thus earning the Hearthome Ribbon, his second ContestRibbon overall.
The Hearthome Ribbon
The city's Tag Battle tournament began in Tag! We're It...!, where it was revealed that the competing Trainers would be randomly paired up by a computer. For this reason, Ash, Dawn, and Brock got tagged with Paul, Conway, and Holly, respectively. During the first round, they all managed to defeat their opponents and, in Glory Blaze!, they proved successful once again by winning their battles in the second round. Before the semifinals, Paul released his Chimchar due to its inability to activate Blaze during their last battle. Chimchar was then invited to join Ash's team. In Smells Like Team Spirit!, Dawn and Conway made it to the finals while Paul and Ash went up against Brock and Holly. Brock's Croagunk and Holly's Farfetch'd were no match for Paul's Torterra and they were easily defeated, bringing Ash and Paul to the finals. There, Ash and Paul sent out Chimchar and Elekid while Dawn and Conway called out Buizel and Heracross. During their battle, Paul's Elekidevolved into Electabuzz, which helped Ash and Paul win the competition.
In Arriving in Style!, the group returned to Hearthome City for Ash's Gymbattle, only to find out the Gym Leader was still out of town developing a new battling style. While in the city, Ash and Dawn were invited by Paris to enter the Hearthome Collection, a fashion show for Stylists and their Pokémon where the winner gets to work on a photo shoot for the Poké Chic magazine. Together with Cocoa and Jessilina, Ash and Dawn entered the event. In the end, Ash, Dawn, and Cocoa were chosen by Paris and Hermione as the three finalists. When the results were announced, it was revealed that Ash and Pikachu had placed third and would be given the Unique Award for their originality, while Cocoa and Mismagius would receive the Accessory Award as a prize for getting to second place. Dawn and Buneary were declared as the big winners, but Dawn said she wouldn't be taking part in the Poké Chic campaign in order to focus on her Coordinatortraining.
The trio later return to Hearthome City together with Fantina from Celestic Town, and Platinum later challenges her in a Gym battle. After winning the battle, Platinum learns that her father was captured, and Fantina lends her Drifblim so that the trio can get to Canalave City quickly.
The city is a fashion capital according to Platinum's Sinnoh travel guide.
A woman in the city mentions that she evolved one of her Pokémon with a Water Stone; however, none of the Pokémon in the Sinnoh Pokédex evolve via Water Stone. In Pokémon Platinum, her dialog is changed to reference a Fire Stone instead. Either way, no Pokémon in the original Sinnoh Pokédex can evolve using these two evolutionary stones, with only Eevee in the Platinum extension making use of them.
In the anime, Enta is the mayor of Hearthome City. However, this is only mentioned in the dub.
