Description

Mount Akaishi, or Akaishidake (赤石岳; 3,120 m), is the 7th-highest peak in Japan and lies at the heart of the Southern Japan Alps (Minami Alps), right on the border between Shizuoka and Nagano Prefectures. The name 'Akaishi' means 'red stone', referring to the distinctive reddish radiolarian chert that also gives the entire Akaishi Mountains their name. It is one of the Hyakumeizan (100 Famous Japanese Mountains) and has lain within Minami Alps National Park since 1964. Its summit holds Japan's highest first-order triangulation station (3,120.53 m), and on its eastern flank a cirque preserves traces of Japan's southernmost glacier. Unlike the easily reached Tateyama, Akaishidake is renowned precisely for its remoteness: ascents usually start from Sawarajima and demand nearly 2,000 m of climbing plus one to three nights in mountain huts, often linked as a ridge traverse with the Arakawa Sanzan (Warusawa). Above the treeline grow Siberian dwarf pine and alpine flower meadows that are habitat for the rock ptarmigan (raichō).

Routes

Sirkuit Sawarajima (椹島) via punggung Higashione — jalur baku

Berat (non-teknis) — pendekatan panjang dan tanjakan curam berkepanjangan; perlu menginap di pondok, kebugaran, dan kesiapan cuaca

Umumnya 1–2 malam; ~2.000 m tanjakan dari Sawarajima (~1.120 m) ke puncak (3.120 m)

The most common route up Akaishidake starts from Sawarajima (椹島, ~1,120 m), a base reached by dedicated bus from Hatanagi. From here the trail climbs steeply nearly 2,000 m through forest and past the treeline to the summit ridge, with the Akaishi-goya hut and Akaishi emergency hut for overnight stays. Many hikers do it as a Sawarajima circuit linking Akaishidake with neighbouring peaks. There is no technical climbing, but the remoteness, length, and altitude above 3,000 m make it a serious undertaking; the normal season runs from around mid-July to early October when the huts are open.

Traverse Arakawa Sanzan (Warusawa/Akudawa) → Akaishidake

Berat (non-teknis) — traverse punggung tinggi jarak jauh; menuntut stamina, manajemen pondok, dan cadangan cuaca

Sekitar 3 hari lintas punggung di bagian terdalam Alpen Jepang Selatan

A classic traverse linking the three Arakawa peaks (Arakawa Sanzan — including Warusawa/Akudawa, the high point of the Southern Alps) with Akaishidake in a single ridge crossing of about three days. From Sawarajima the trail climbs to the Arakawa peaks, then follows the high ridge above 3,000 m to Akaishidake, staying in huts along the way (e.g. Senmai-goya, Arakawa-goya, Akaishi-goya). The route traverses the deepest, most remote part of the Minami Alps with sweeping panoramas, alpine flower meadows, and chances of spotting raichō, but demands acclimatisation, stamina, and spare days for high-mountain weather.

Climbing Experiences

Akaishidake (3,120 m) is the peak that gives its name to Japan's Southern Alps (Akaishi Range) and one of the 100 Famous Mountains (Hyakumeizan) — notable as the most remote of the Japanese Alps, with no railway or ropeway access. The Japanese-language videos below record ascents and traverses from Sawarajima, while the English guides (THE JAPAN ALPS, Daringdaddy, RidgelineImages) detail trail stages, hut logistics, and traverse experience for planning.
