45. Mt Fuji 富士 or Fuji-san as it is called in Japan is the highest mountain in Japan at 3,776 meters or 12,388 feet in altitude. Mt Fuji is an active volcano that last erupted in 1707 killing hundreds of people and started fires as far away as Tokyo. By most counts, Fuji is due for another eruption as its cycle appears to be every 300 years. Fuji straddles Shizuoka and Yamanashi prefectures just west of Tokyo from where it can be seen on a clear day. Mount Fuji's symmetrical cone is a well-known symbol of Japan and is frequently visible in works of art. Although Mount Fuji has not erupted in over 300 years it's still not extinct.
