Kanto is the first region visited in the Pokémon video game series.
It is the setting of Pokémon Red, Green, Blue, and Yellow and contains the original eight Gym Leaders, the Pokémon League, and Professor Oak's laboratory in Pallet Town. Kanto was also the setting for the first season of the Pokémon anime.
The region's name comes from the real-world Kantō region of Japan, which includes Tokyo and surrounding prefectures. Pokémon's fictional Kanto uses familiar Japanese-inspired geography while adding routes, towns, caves, islands, and the Safari Zone.
Kanto is sometimes confused with Johto because the two regions appear together in Pokémon Gold, Silver, and Crystal. Johto is the second-generation region, while Kanto is the original setting and home of the first Pokédex.
