Spanning the Tokyo metropolitan area and six other prefectures in eastern Honshu (Kanagawa, Saitama, Chiba, Tochigi, Gunma, and Ibaraki), the Kantō region is, in many ways, Japan’s heartland. It’s where the modern Japanese nation emerged, through the city of Edo (that became Tokyo), and where Japan became the industrialized powerhouse it is today. Although there are fewer historical and cultural attractions here than in rival region Kansai (largely because Tokyo was so heavily bombed in World War II), Kantō more than makes up for this in the richness of its modern attractions. You’ll never be short of things to do in Kantō.
