About Fuji volcano: Fuji of 3776m high is the hightest peak in Japan. 470,000 people are living around the volcano. 400,000 people climb for one year; 30 milion tourists visit for all the season. (1) Basaltic stratovolcano of the edifice volume of 500-400 km3. (2) Occational explosive eruptions make steep slope, and causes various volcanic hazards. (3) Variation in eruptive volume and eruption interaval. After the last eruption, the explosive Hoei 1707 eruption on the southeastern flank, the activity is low without eruption.

Eruptive history of Fuji volcano (one of summaries of GSJ (Yomamoto et al., 2005)) : Fuji volcano started to grow 100 ka. Tanukiko debris avalanche BC 18,000. Voluminous effusions of lava flows occurred during BC15,000 - BC6,000. The eruptive activity became high at the summit and flank during BC3,600-BC1,700. The eruption style had changed into explosive from the summit and flank. The last summit eruption ( S-22) occurred at BC300. Immediately after S-22, eruptions repeated at the fanks. The frequency of flank eruptions became high during AD 700-1000. Around AD1000 the flank eruptions occurred both on the north and south flanks. The last eruption is the Hoei 1707 eruption.
