Mt. Oku-Hotaka is the main mountain of the Hotaka Mountain Range, which straddles Nagano and Gifu prefectures in the Hida Mountain Range of Chubu-Sangaku National Park in the southern part of Japan's Northern Alps. At 3,190 meters above sea level, it is the highest peak in the Northern Alps and the third highest in Japan after Mt. Fuji and Mt. Kita.
Mt. Oku-Hotaka (奥穂高岳), Mt. Karasawa (涸沢岳), Kita-Hotaka (北穂高岳), Mae-Hotaka (前穂高岳), Nishi-Hotaka (西穂高岳), and Mt. Myojin (明神岳), are collectively referred to as Mt. Hotaka.

It is said that the origin of the mountain's name comes from a legend that a god named Hotakami-no-Mikoto descended to the summit of Mt. Oku-Hotaka. Even today, the mountain is revered as a sacred mountain by local people, who visit and climb it to pray.

The first person to summit Mt. Oku-Hotaka was surveyor Gunji Abe in 1906. With its challenging routes, powerful rocky ridges, and panoramic views from the ridge, Mt. Hotaka continues to attract many climbers to this day.

The Geological Features of Mt. Oku-Hotaka

Here, we'll take a look at the geological features of Mt. Oku-Hotaka
・Volcanic Terrain
Mt. Hotaka, including Mt. Oku-Hotaka, is formed mainly of dacitic ignimbrite called "Hotaka andesite." This rock was formed by pyroclastic flows during an eruption approximately 1.75 million years ago, and was uplifted 2,000m over a period of 1 million years after a large-scale eruption.

・Glacial Landforms
Many glacial landforms have been observed on Mount Hotaka. Glacial landforms are landforms created by glaciers that have accumulated soil, sand, rocks, etc., while carving away the land below.

Mt. Oku-Hotaka – Uma no Se

Mt. Okuhotaka, a famous mountain climbing spot, has a narrow ridge called "Uma no Se" (horse's back), which is steep and features cliffs on both sides. Because of how steep it is, it's also a dangerous place where falling accidents occur frequently.

The slopes, which look like a combination of rubble, require extreme caution in order to prevent accidents. In the video, you can see how they decide not go to Gendarme (a rocky summit between Mt. Oku-Hotaka and Mt. Nishi-Hotaka), and instead decide to descend via Uma no Se. It's as realistic as if you were there yourself. The sound of the wind, the hands gripping the rocks, the shadows of climbers moving toward the spectacular views... the power of these scenes draws you in.
