Kanto

Kanto Region, introduced in Red and Green (Blue in international releases), later seen in Yellow, Gold, Silver, Crystal, FireRed, LeafGreen, HeartGold, and SoulSilver, was the first region in the Pokémon series. It is attached to the Johto region so the player can also visit it by train or jetboat in Gold, Silver, Crystal, HeartGold and SoulSilver. In these games, however, the region differs from the earlier games (which are set three years previously) in several plot and graphical points. In the games, its cities are named after colors. Two areas of the Kanto region, Saffron City and the Pokémon Stadium, are playable stages in Nintendo's popular Super Smash Bros. fighting games. In the anime, Ash travels in Kanto in the Kanto and Battle Frontier seasons. Kanto represents the actual region in Japan called Kantō, which is its namesake, and eastern Tōkai.
