Description

Ainodake (間ノ岳, 'Mount Aino'; 3,190 m) is a peak in the Akaishi Mountains — part of Japan's Southern Alps — within Minami Alps National Park. At 3,190 m it is the third-tallest mountain in Japan (after Fuji and neighbouring Kita-dake) and the second-highest in the Akaishi Mountains. Its summit sits exactly on the border of Shizuoka Prefecture (Aoi-ku and Minami-Alps City) and Yamanashi Prefecture, and it is one of the '100 Famous Japanese Mountains' (Nihon Hyakumeizan) selected by Kyūya Fukada. Ainodake is rarely climbed on its own; it is almost always part of a ridge traverse with its neighbour Kita-dake (3,193 m) — so its classic lines are the Kita-dake–Aino-dake traverse from the Hirogawara trailhead, or the three-peak Shirane Sanzan traverse (Kita-dake–Aino-dake–Nōtori-dake). The broad ridge above 3,000 m linking Kita-dake and Aino-dake offers views of Mount Fuji and the Southern Alps chain, and is one of Japan's most prized high-ridge walks.

Routes

Traverse Kitadake–Ainodake dari Hirogawara

Pendakian alpine berat namun non-teknis; punggungan tinggi di atas 3.000 m

2 hari (menginap di pondok Kitadake-sansō atau Kata-no-koya)

The classic route to Ainodake begins at the Hirogawara trailhead (~1,520 m) in Yamanashi Prefecture. On day one, climbers ascend past Shirane-Oike-goya to the summit of Kita-dake (3,193 m, Japan's second-highest), then descend slightly to the Kita-dake-sansō hut to overnight. On day two they follow the broad, high ridge over Naka-shirane to the summit of Aino-dake (3,190 m), then return by the same route to Hirogawara. The Kita-dake–Aino-dake ridge, which stays above 3,000 m, offers views of Mount Fuji and the Southern Alps chain and is one of Japan's most popular high-ridge walks. It requires no technical gear in summer, but fast-changing weather and altitude demand fitness and preparation.

Traverse Shirane Sanzan (Kitadake–Ainodake–Nōtoridake)

Traverse alpine berat multi-hari; non-teknis namun panjang dengan jalur turun terpencil

3 hari (dua malam di pondok/tenda)

A more ambitious route is the three-peak Shirane Sanzan traverse, linking Kita-dake (3,193 m), Aino-dake (3,190 m), and Nōtori-dake (3,026 m) along one high ridge. It usually starts from Hirogawara, crosses Kita-dake and Aino-dake as on the classic route, then continues south over Nishi-Nōtori-dake and Nōtori-dake before a long descent via the Ōmonzawa trail to Naradaira. The traverse keeps hikers at 3,000 m for a long stretch with few escape routes, demanding stamina, weather management, and high-mountain experience. In return it delivers one of the grandest 3,000 m ridges in Japan's Southern Alps.

Climbing Experiences

Ainodake (間ノ岳, 3,190 m), Japan's third-highest mountain in the Akaishi Mountains (Southern Alps), is almost always climbed together with its neighbour Kita-dake via a ridge traverse from Hirogawara, or as part of the three-peak Shirane Sanzan traverse (Kita-dake–Aino-dake–Nōtori-dake). The records below present real climbing footage of this high ridge from various Japanese hikers.
