The Kanto Region

The Kanto region is a region of the Pokémon world. It is located east of Johto, and as revealed by the radio show Sinnoh Sound, is located south of Sinnoh.

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 Pokémon Trainers 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.

Geography
The Kanto region has a very temperate climate and not many notable landscape features, though this may be due to the region's origins in the Generation I games.
The majority of the Kanto region are forests and plains. Many of the major Kanto cities are in the center of the region, with close access to virtually every environment such as the sea, mountains, forests, etc. Kanto is mostly dominated by land, but has a large bay in the middle which opens to a sea in the southwest. Kanto has a contrast between urban cities and rural towns. Cinnabar Island is unique in a way that it is built on top of a mountain. The rest of Kanto's cities and towns are generic. Kanto has several mountain ranges, which are mostly in northern and western Kanto. Indigo Plateau and Victory Road mountain range divides Kanto from the neighboring Johto region.
