Kantō Region

The Kantō region (関東地方 Kantō-chihō^?) is a geographical area of Honshu, the largest island of Japan.^[1]

The region includes the Greater Tokyo Area and encompasses seven prefectures: Gunma, Tochigi, Ibaraki, Saitama, Tokyo, Chiba, and Kanagawa.

Within its boundaries, slightly more than 40 percent of the land area is the Kantō Plain.
The rest consists of the hills and mountains that form the land borders.

In official census count on October 1, 2010 by the Japan Statistics Bureau, the population was 42,607,376 s^[2] amounting to approximately one third of the total population of Japan.

The heartland of feudal power during the Kamakura period and again in the Edo period, Kantō became the center of modern development.

The Kantō region is the most highly developed, urbanized, and industrialized part of Japan.

The Kamakura period (鎌倉時代 Kamakura jidai^?, 1185–1333) is a period of Japanese history that marks the governance by the Kamakura Shogunate, officially established in 1192 AD in Kamakura, by the first shogun Minamoto no Yoritomo. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan.
The Edo period (江戸時代 Edo jidai^?), or Tokugawa period (徳川時代 Tokugawa jidai^?) is the period between 1603 to 1868 in the history of Japan when Japanese society was under the rule of the Tokugawa shogunate and the country's 300 regional Daimyo. The period was characterized by economic growth, strict social orders, isolationist foreign policies, an increase in both environmental protection and popular enjoyment of arts and culture.
