Honshu alone contains over 60 percent of Japan's population and includes Tokyo, Osaka, Kyoto, and Nagoya. The Japanese archipelago sits on the Pacific Ring of Fire where the Pacific, Philippine Sea, Eurasian, and North American tectonic plates converge, creating the volcanic and seismic activity that shapes regional geography. Mount Fuji rises 3,776 meters on southern Honshu between Shizuoka and Yamanashi prefectures, last erupting in 1707 during the Edo period.
