Mount Yōtei (羊蹄山 Yōtei-zan, literally "sheep-hoof mountain") is an inactive[2] stratovolcano located in Shikotsu-Toya National Park, Hokkaidō, Japan. It is also called Yezo Fuji or Ezo Fuji (蝦夷富士), "Ezo" being an old name for the island of Hokkaido, because it resembles the more famous Mount Fuji. The mountain is also known as Makkari Nupuri (マッカリヌプリ) 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]
