Mount Hotaka is the collective name for a magnificent group of mountains in the Hida Mountains, part of Chubu-Sangaku National Park. The range is centered on Mount Okuhotaka, which rises to 3,190 meters, making it the third-highest mountain in Japan. It is also recognized as one of Japan’s 100 Famous Mountains, New 100 Famous Mountains, and 100 Famous Flower Mountains.
Together with Mount Yari, the Hotaka peaks form the celebrated Yari-Hotaka Mountain Range. Their dramatic ridgelines, steep rock walls, and demanding alpine environment have made them a dream destination for generations of mountaineers.
At the heart of the Hotaka range stands Mount Okuhotaka, the highest mountain in the Northern Alps. Around it are Mount Karasawa, Mount Kitahotaka, Mount Minamidake, Mount Nakadake, and Mount Obami, while Mount Yari rises farther to the north.
These peaks form the Yari-Hotaka Mountain Range, with a rugged ridgeline extending from north to south. The mountains are characterized by rocks known as Hotaka Andesite, while traces of ancient glacial erosion can be seen throughout the range. Steep cliffs and dramatic rock faces create the spectacular landscape for which the Hotaka mountains are famous.
To the east of Mount Okuhotaka, the ridge continues toward Byobu-no-Kashira, Mount Maehotaka, and Mount Myojin. Mount Maehotaka and Mount Okuhotaka are connected by a narrow ridge known as the Tsurione, or “Hanging Ridge.”
The rocky peaks between Mount Maehotaka and Mount Myojin have distinctive forms that have also been associated with mountain worship. Individual peaks in this group are traditionally identified by number, reflecting the area’s long history of sacred mountain traditions.
Southwest of Mount Okuhotaka, the ridge continues toward Mount Nishihotaka and Nishihotaka Doppyo. These peaks are also popular destinations for experienced hikers seeking dramatic ridgeline scenery.
Many visitors approaching Mount Hotaka use Kamikochi in Nagano Prefecture as their base. From Kamikochi, a variety of mountain trails lead toward Mount Maehotaka, the Karasawa area, and Mount Okuhotaka, allowing hikers to experience the changing landscape as they gain elevation.
One of the most spectacular destinations is the Karasawa Cirque, located between Mount Okuhotaka and Mount Maehotaka. Snowfields can remain here even during summer, while in autumn the surrounding slopes turn brilliant shades of red, orange, and yellow, creating one of the most impressive mountain landscapes in the Northern Alps.
Mount Hotaka has been regarded as a sacred mountain since ancient times. Because of its distinctive peaks, it was once known as Goheidake, a name that compared the mountain’s shape to a sacred Shinto ritual wand.
Historical documents from the Edo period use names such as Hodakadake and Hotakadake, suggesting that the mountain had long been recognized as an object of worship. A record from 1690 states that the Buddhist monk Enku climbed the mountain. The peaks were subsequently revered as part of the sacred domain associated with Hotaka Shrine.
Mount Hotaka also holds an important place in the history of modern mountaineering in Japan. In 1880, British explorer William Gowland climbed Mount Myojin with the local guide Kamijo Kamonji.
In 1893, surveyor Kiyohiko Tate and missionary and mountaineer Walter Weston climbed Mount Maehotaka. Later, in 1906, Gunji Abe is recorded as making an ascent of Mount Okuhotaka. In 1909, Masao Udono successfully completed a traverse from Mount Yari to the Hotaka mountains, contributing to the development of the modern Yari-Hotaka traverse route.
From the Taisho period into the early Showa period, numerous mountain huts were established around the Hotaka range, helping alpine climbing culture develop in Japan. Hotakadake Sanso opened in 1924, and the following year saw the beginning of the history of technical rock climbing in the Takidani area, including an ascent by climbers such as Kuzo Fujiki.
After World War II, facilities including Kitahotaka Hut and Karasawa Hut were developed. Today, mountain huts and designated camping areas are distributed along the trails from Kamikochi, providing places for hikers to rest and supporting safe travel through the alpine environment.
The dramatic terrain of Mount Hotaka has been shaped by both volcanic activity and glacial erosion. Approximately 1.75 million years ago, volcanic activity produced the Hotaka Andesite that forms much of the mountain range. Enormous pyroclastic flows were followed by uplift over immense periods of time, eventually creating the steep mountains seen today.
During the Ice Ages, glaciers further transformed the landscape. Glacial erosion carved U-shaped valleys and cirques, including the spectacular Karasawa Cirque. These glacial landforms are scientifically important examples of Japan’s alpine geological heritage.
From spring into summer, melting snow reveals alpine vegetation, with high-altitude flowers blooming along the mountain trails. In autumn, the entire mountain landscape is covered in brilliant foliage, while winter brings deep snow and a profound sense of silence.
The combination of harsh conditions and extraordinary beauty is one of the defining characteristics of the Hotaka mountains. Every season presents a different face of this high-altitude environment.
Mount Hotaka offers a variety of routes, ranging from established approaches to highly demanding alpine traverses. The most common route runs from Kamikochi through Karasawa to Mount Okuhotaka. More demanding options include the Jutaro Shindo and Shiradashi Valley routes, while experienced mountaineers can attempt the Yari-Hotaka traverse.
The route passing through Gendarme toward Mount Nishihotaka is regarded as one of Japan’s most technically demanding mountain routes. Its exposed ridges and steep terrain make it a destination for highly experienced mountaineers.
Mountain huts including Hotakadake Sanso, Karasawa Hut, and Nishi-Hotaka Sanso are located along the major routes. Medical clinics may also operate in the area during the summer climbing season.
These facilities provide accommodation, rest, and support for hikers traveling through the challenging alpine environment. However, conditions in the Hotaka range can change rapidly, and routes vary greatly in difficulty, so appropriate preparation and mountain experience are essential.
Mount Hotaka is one of the defining landscapes of the Northern Alps, where spectacular natural forces and a long history of human exploration come together. Volcanic activity and glaciers created its dramatic terrain, while alpine plants and wildlife enrich its high-altitude environment. Generations of climbers have also contributed to a distinctive mountaineering culture around these peaks.
Seen from Kamikochi, the imposing Hotaka skyline captures the grandeur of Japan’s mountain landscapes. From its sacred traditions and pioneering ascents to its glaciers, alpine flowers, and rugged ridges, the Hotaka range continues to offer an unforgettable encounter with the high mountains of Japan.
