 As the historical center of Japanese cultural and political power, the island includes several past Japanese capitals, including Kyoto, Nara and Kamakura.Much of the island's southern shore forms part of the Taiheiyō Belt, a megalopolis that spans several of the Japanese islands.Most of Japan's industry is located in a belt running along Honshu's southern coast, from Tokyo to Nagoya, Kyoto, Osaka, Kobe, and Hiroshima; by contrast, the economy along the northwestern Sea of Japan coast is largely based on fishing and agriculture.
