Mount Aino, or Ainodake, is one of the 100 Famous Japanese Mountains. At 3,189 m (10,463 ft), its peak lies in the Akaishi Mountains (referred to as the Southern Alps) of Japan on the border of Aoi-ku, Shizuoka, Shizuoka Prefecture, and Minami-Alps, Yamanashi Prefecture. It is the fourth tallest peak in Japan and the second highest in the Akaishi Mountains.
Within the Akaishi Mountains, Mount Aino is situated roughly 3 km (2 mi) south of Mount Kita, the ranges' tallest peak. Together with Mount Nōtori to the south the three mountains may be referred to as Shiranesanzan.
