Description

Mount Ontake (御嶽山, 3,067 m) is a stratovolcano rising on the border of Nagano and Gifu Prefectures in the Kiso region of central Japan. It is the second-highest volcano in Japan after Mount Fuji and the country's 14th-highest mountain, and is listed among Kyūya Fukada's '100 Famous Japanese Mountains' (1964). For centuries Ontake has been a sacred peak and a centre of mountain worship (the Ontake-kyō faith and Shugendō tradition), so its trails are lined with small shrines, statues and pilgrim monuments. On 27 September 2014 the volcano erupted phreatically with almost no warning while many hikers were on the summit on an autumn weekend; the disaster killed at least 58 people and was Japan's deadliest volcanic eruption since World War II. Since then parts of the summit and crater area have been restricted, and climbers are urged to check volcanic-activity status before ascending.

Routes

Rute Kurosawa lewat Ontake Ropeway (sisi Kiso)

Menengah–berat; ±900 m beda tinggi dari stasiun atas kereta gantung, tanpa pemanjatan teknis

±7–8 jam pulang-pergi

The most popular approach: the Ontake Ropeway lifts hikers to about 2,150 m, then the trail passes Nyonindō, Ishimuro-sansō and the crater lakes (Ni-no-Ike/San-no-Ike) toward the Ken-ga-mine summit area. The route is lined with stone monuments and shrines of the Ontake mountain-worship tradition.

Rute Ta-no-hara menuju Ken-ga-mine

Menengah–berat

±6–8 jam pulang-pergi

The standard current route from the Ta-no-hara trailhead (~1,720–1,820 m) through forest to Hachi-go-me (~2,500 m), then up an exposed ridge to the Ken-ga-mine area (~3,010 m) — the practical upper limit while the crater rim/true 3,067 m summit remains restricted.

Rute Ōtaki-guchi (Otaki)

Berat; curam. Bagian atas dari Ōtaki-Chōjō ke Kengamine ditutup lama sejak erupsi

±6–8 jam pulang-pergi (jalur naik terpendek)

The shortest route to the top, starting from Ōtaki Village (~8.8 km). It was the trail with the most 2014 casualties; the upper section from Ōtaki-Chōjō to Kengamine is under long-term closure and the boundary has shifted several times — confirm the current limit before going.

Climbing Experiences

Climbing Mount Ontake (3,067 m) is generally a signed day trek rather than a technical climb, with several popular trailheads: the Kiso side via the Ontake Ropeway (Kurosawa route), the shortest Ōtaki-guchi route, and the Ta-no-hara route to Ken-ga-mine. The trails are dotted with small shrines and pilgrim monuments reflecting the Ontake mountain-worship tradition. Since the deadly phreatic eruption of 27 September 2014 — which killed dozens of hikers on the summit — parts of the crater area have been restricted (exclusion zone), and the accessible high point is usually the Ken-ga-mine area. Hikers stress checking the volcanic-activity status (JMA warning level) and the latest restricted-area map before setting out.
