Mt. Hiuchi is a 2,462m peak spanning Itoigawa City and Myoko City in Niigata Prefecture. It is celebrated as one of Japan's 100 Famous Mountains and 100 Famous Flower Mountains, serving as the highest peak of the K seniority mountain range. The mountain features a gentle ridge running east to west, with relatively mild slopes near the summit. It is a treasure trove of alpine flora; the wetlands around Takaya-ike Pond and the area around Raicho-hiroba (Rock Ptarmigan Plaza) are critical sites for nature observation and wildlife spotting.
The region has records of settlers in the Sasagamine area since the late Edo period. Historically, the area has seen the construction of several structures, including a Sasagoya hut in 1913 and the Kyo-dai Hut in 1928. In 1930, a forestry hut was built, which is the predecessor to the current Takaya-ike Hut. Interestingly, during maintenance of the summit's survey markers in the 1950s, two bronze statues of the Eleven-faced Kannon, believed to date back to the Kamakura period, were discovered. Today, the area is strictly protected as part of the Myoko-Togakushi Renzan National Park.

The greatest draw of Mt. Hiuchi is the diversity of its alpine plants and the sweeping landscapes they create. You can find abundant species such as Primula c restelliana, various monkshood, and Eriophorum (cottongrass). The area near Raicho-hiroba is a famous habitat for the rock ptarmigan, offering a rare chance to encounter this elusive bird. On clear days, the summit provides a panoramic view that includes Mt. Fuji, the Yatsugatake Mountains, the Tateyama Mountains, the Noto Peninsula, and Sado Island. The changing colors of the mountain slopes and the scenery of the Takaya-ike wetlands are essential experiences for hikers.
The best time to visit Mt. Hiuchi is from early summer to summer, when the snow melts and plants begin to bloom. The period from May to September is ideal for hiking and botanical observation. Summer is particularly popular as it is the peak blooming season for alpine flowers. However, in early summer, snow patches may still remain near the summit, so hikers should be prepared for rapid environmental changes and carry appropriate gear.

Hiking is the primary activity here. Popular routes include the path from the Sasagamine side or traversing through Mt. Myoko. Mountain huts near the summit are operated by staff during certain periods of the climbing season. Visitors can enjoy walking around the Takaya-ike wetlands to observe alpine flora and the rare rock ptarmigan. In winter, the surrounding area is also utilized for mountain skiing.
Mt. Hiuchi is surrounded by famous peaks like Mt. Myoko and Mt. Yake. At the foot of the mountains, you will find leisure facilities such as Charm Hiuchi Ski Resort, Akakura Onsen Ski Resort, and Myoko Suginohara Ski Resort. These serve as bases for different seasonal activities, from summer trekking to winter skiing. The area also marks the headwaters of rivers like Sekikawa and Noe River.
Equipment capable of handling rapid weather changes is essential. Because temperatures drop significantly at high altitudes, bring warm layers and waterproof gear. Always check official information regarding mountain hut availability and your trekking schedule. As this is a protected natural area, please follow the 'Leave No Trace' principle: carry all your trash out and respect the local environment. It is vital to obtain the latest information on hut operations and trail safety before your ascent.
