Mt. Notori, Mountain summit in Minami Alps National Park, Japan

Mount Nōtori is a 3,026 m peak in the Akaishi Mountains, within Minami Alps National Park. Its summit area splits into two tops: the southeastern Mount Nōtori, which carries the triangulation point, and the higher northwestern Mount Nishinōtori at 3,051 m. The summit lies on the Yamanashi–Shizuoka prefectural border and is surrounded by a dwarf-pine zone above the treeline.

Mount Nōtori is one of the Shiranesanzan, the "three white summits" formed with Mount Kita and Mount Aino in the northern Akaishi Mountains. Until the Meiji era the name was not fixed: because a similar snow patch appears on Mount Aino, that peak was sometimes called Nōtori. The name comes from a snow figure on the east face resembling a white bird, taken as a signal for rice planting.

The name comes from a snow patch on the east face that, after the spring thaw, takes the shape of a white bird; this snow shape signalled the time for rice planting. Because a similar patch also appears on Mount Aino, the name was not fixed until the Meiji era, and Mount Aino was sometimes called Nōtori. The peak is listed among the 200 Famous Mountains of Japan, the New 100 Famous Mountains and the 100 Famous Mountains of Yamanashi.

Mountain huts at the location provide shelter and rest stops for climbers during their ascent. Connected trails lead to neighboring peaks, allowing visitors to choose routes based on their fitness level and time available.

The mountain spans across two prefectures, with its territory divided between Hayakawa in Yamanashi and Aoi-ku in Shizuoka. Climbers cross these administrative boundaries while ascending, experiencing a subtle shift in jurisdiction from one side of the ridge to the other.
