From Bulbapedia, the community-driven Pokémon encyclopedia.
The Pokémon Journal (Japanese: ポケモン ジャーナル Pokémon Journal) is a magazine that has appeared in many of the core series games. In Pokémon Omega Ruby and Alpha Sapphire, the magazine is called Aha! Pokémon Journal (Japanese: しって なるほど ポケモン ジャーナル Now I get It! Pokémon Journal). Excerpts from the magazines can only be read in Pokémon FireRed and LeafGreen and Pokémon Omega Ruby and Alpha Sapphire. In FireRed and LeafGreen, it is a gossip magazine, and the articles serve as a source for Fame Checker entries. In Omega Ruby and Alpha Sapphire, it is an informative magazine, with the articles providing basic advice and highlighting certain gameplay mechanics.
Pokémon FireRed and LeafGreen
Most Pokémon Journal articles are found in the bookshelf in the back of a Pokémon Center, though they can be found in other buildings like a school in Viridian City and Celadon Mansion. Journal entries that mention Gym Leaders or Elite Four members do not appear until after the player has defeated everyone mentioned in them, and the Journal entry on Mr. Fuji in the Cinnabar Island Pokémon Center does not appear until after defeating the Elite Four. Although Pokémon Journals can be found on the Sevii Islands, according to a Gentleman, the newest copy is missing from Four Island during the events of Pokémon FireRed and LeafGreen.
Pokémon Omega Ruby and Alpha Sapphire
The journal returns in Omega Ruby and Alpha Sapphire as the Aha! Pokémon Journal. It can be found on the bookshelves at the back of every Pokémon Center in the Hoenn region. The articles offer basic gameplay hints and tips.
