Japan Photo Guide

The Kantō region (Japanese: 関東地方, Kantō-chihō) is a geographical area of Honshū, the largest island in Japan. The region encompasses seven prefectures around Tokyo: Gunma, Tochigi, Ibaraki, Saitama, Tokyo, Chiba, and Kanagawa. Its boundaries are roughly the same as those of the Kantō plain. The plain itself, however, only makes up slightly more than 40 percent of the region. The rest consists of the hills and mountains that border it except on the seaward side.

The Kantō region is the most densely populated are of Japan with cities like Tokyo and Yokohama, but also has some nice nature with places like Kamakura and Nikko.
