1. For mountain climbers of the Northern Alps in Japan

First and foremost, the Northern Alps are noted for their high elevation.
Eight peaks are more than 3,000 meters in height, and almost all of the other mountains are above 2,500 meters, which is above the timber line. Climbers need to prepare themselves for the special weather conditions of high mountain ranges such as strong winds, cold temperatures, snow, and geographical features.

5. History of Enzanso

Enzanso was founded by Chihiro Akanuma in 1921 and was passed on through three generations: from Chihiro, through Atsuo, and to Kenji Akanuma. The current main building was built in 1935, and the timber used in its construction was carried by hand from around the third bench (elevation 2,000 m). From the time of its founding, they have served items such as coffee, tea, as well as curry and rice, which was a very modern menu at that time and has continued to the present day. The “Sun Room” cafeteria is one of the most popular features of Enzanso. While enjoying coffee, cake, and draft beer, you can enjoy a beautifully scenic sunrise and views of Mt. Fuji, Mt. Asama, and Nagano. Special bedding (futon type sleeping bag) was jointly developed by Mizuno Corporation and Kenji Akanuma. Made from a cotton material that greatly retains heat, it also eliminates odors and bacteria, and remains dry. It is always comfortable and kept clean.Toilets are a portaloo style.

Rock ptarmigan

Rock ptarmigan can be seen from Mt. Kita-Tsubakurodake, along the ridgeline of Omote-ginza course, and around Enzanso. Japan’s rock ptarmigan are carefully protected, so they are not afraid of humans – a fact that is quite surprising for ptarmigan researchers around the world.

Komakusa (dicentra peregrina)

In July the pale pink komakusa, commonly called “queens of alpine plants”, begin to bloom.

Strange rocks

In the area around Mt. Tsubakurodake and Enzanso, you can enjoy a number of strangely shaped rocks such as Dolphin Rock, Gorilla Rock, Spectacles Rock, and Lion Rock.
