The Kanto is a Japanese region, located on the East of the main island of Honshu. It gathers seven prefectures in total (Tokyo, Chiba, Gunma, Ibaraki, Kanagawa, Saitama and Tochigi) and is home of the two biggest cities (by number of inhabitants) of the archipelago. It is the most populated, industrialized and one of the most touristic territories of Japan.
The Kanto is without a doubt the region of Japan (equal to the Kansai) which appeals the most to foreign visitors in Japan. Indeed, it is the home region of the japanese capital, the center of all desires which allows to visit not only the capital of Japan but all its surroundings as well.
The Kanto is lined with the Chubu region on its West side, the Tohoku region on its northern side and the Pacific Ocean on the East and South.
As an anecdote, it is also the first area of the island explored in many Pokémon games.
