Mount Yōtei (羊蹄山, Yōteizan^?) is an active^[2] stratovolcano located in Shikotsu-Toya National Park, Hokkaidō, Japan. It is also called 'Yezo Fuji or Ezo Fuji (蝦夷富士^?), because it resembles the more famous Mount Fuji. The mountain is also known as Makka Nupuri (マツカリヌプリ^?) and Mount Shiribeshi (後方羊蹄山, Shiribeshi-Yama^?).^[2] It is one of the 100 famous mountains in Japan.

Geology

Mount Yotei is mostly composed of andesite and dacite.^[2][3] The stratovolcano is symmetrical adding to its resemblance to Mount Fuji.

Eruptive history

Tephrochronology indicates two eruptions at Mount Yotei. The most recent circa 1050 BC from a cone emerging from the northwest flank of the mountain at Lake Hangetsu (Hangetsu-Ko). The earlier eruption is dated from circa 3550 BC.^[4]
