Originally, the region of Johto was based on the entirety of Japan, rather than just the Kansai region, with towns and dungeons based on areas within the country, such as Hokkaido (called North in the Spaceworld 97 demo), Osaka (which was called West and likely became Goldenrod City) and Mt. Fuji (which likely became Mt. Silver). Due to this, Kanto, which was based on the region in Japan of the same name, was compressed into a single map, with Blue as the Gym Leader.
