All cities in Kanto are named after colors (Viridian City, Lavender Town, Indigo Plateau, etc.), with the exception of Pallet Town, which is also a reference to color. Professor Oak is the resident Pokémon Professor and gives Trainer's a choice between Bulbasaur, Charmander, or Squirtle as their starter Pokémon.
Cities, routes, and other locations
The Kanto region features ten towns and cities. There is a wide variety of towns and cities throughout the region; from the large, urban Saffron City to the quiet, quaint town of Pallet. Kanto features a Pokémon League, like most other regions in the Pokémon world. However, since Kanto shares its borders with Johto, it also shares the same Pokémon League. Kanto and Johto are the only known regions that can be crossed with relative ease. Even though Kanto and Johto are culturally and socially different, the two regions are actually very similar in terms of geography.
The Kanto region includes 28 different routes, which acts as roads to cities and towns or points of interest. The Johto region follows Kanto's route number which ends at Route 28 in the Kanto region and begins with Johto's Route 29. Unlike other regions, Kanto does not have routes featuring any sort of weather conditions, such as Hoenn's Route 119 which rains and thunders constantly and Sinnoh's Route 217 in which hail regularly falls. The Kanto region seems to have the most temperate climate of the six main regions.
The connecting landmass between Kanto and Johto doesn't appear to be a fine line; but more or less a blurry one. Route 28 is technically owned by Kanto; however, it bridges the border between the two regions, making it the only route in history that enters two regions at one time. This is similar to Routes 26 and 27, that are strictly Kanto locations.
