Mt. Iizuna, an ascetic mountain that overlooks a vast panorama, is a spiritual home for the people of Nagano.

Course Outline

Famed as hallowed ground, Mt. Iizuna has been the object of mountain peak veneration from long ago. The torii gate and guardian komainu statues at the trailhead, the 13 stone Buddhas quietly standing by the hiking trail, the shrine at the summit, and many other features offer climbers a sense of a sacred atmosphere to this day. The magnificent, 360° panoramic view from the summit is also a key attraction. Mt. Iizuna can be seen from anywhere in Nagano City, making it a symbol of home for residents. Rising 1,917 m above sea level, the famous mountain, which is included among Japan's 200 most famous mountains, is visited by many elementary school climbing outings.

After descending, gaze at Mt. Iizuna from Oyachi Marsh or Daizahoshi-ike Pond and let the lingering satisfaction of the climb sweep over you. Restaurants and hotels with hot-spring day spas surround the area and are a great way to soothe the fatigue of climbing.

Looking toward Zenkoji-daira from the summit of Mt. Iizuna

The panorama peers down upon Zenkoji-daira, and on a clear day even offers views as far as the Northern Alps and Mt. Fuji. At the summit of south peak is a shrine to Iizuna-gongen, the venerated god of the mountain. Iizuna-gongen is worshiped in the form of Karasutengu legendary creatures, which are enshrined in the main shrine building. In the shrine, you can see their appearance. For an authentic climbing experience, the traverse course via Mt. Meno to Mt. Reisenji is highly recommended.
* Only a booth for portable toilets is available near the mountain summit, so do not forget to bring your own plastic bag for toilet usage.
