Mount Iizuna

A cone-shaped volcano in the northwest of Nagano City. It is also written as Iizunayama. It has an elevation of 1,917 meters, but the Iizuna Plateau at the base is about 1,000 meters high, so it can be easily climbed from the base in about two hours. It is included in Myoko-Togakushi Renzan National Park. It erupted on a tertiary tuff layer, and Iizuna Shrine is located near the summit, and a dozen ponds of various sizes are scattered in the depressions of the plateau. It has been a training ground for ascetic monks since the Kamakura period. It is also said to be the birthplace of Iizuna Ninpo. There are only small trees on the summit, but the foothills are covered with a sea of ​​larch trees. From the top, you can see Mt. Asama, the Yatsugatake mountain range, and the Northern Alps in their entirety, making it a wonderful place to relax. A ski resort has been opened on the mountainside, and the foothills are a large area of ​​villas, making it a recreational spot for Nagano citizens.

長野市の北西部にあるコニーデ型火山。飯綱山とも書く。標高1917メートルであるが、裾野(すその)一帯の飯綱高原が1000メートルほどあるので麓(ふもと)からは2時間ほどで容易に登れる。妙高戸隠連山国立公園に含まれる。第三紀凝灰(ぎょうかい)岩層の上に噴出した山で、山頂近くに飯縄神社があり、高原の凹地には大小十数個の池が散在している。鎌倉時代から修験者(しゅげんじゃ)の道場になった。また飯縄忍法の発祥地とされる。山頂には雑木の小木しかないが、山麓(さんろく)はカラマツ樹海をなす。頂上からは、浅間山、八ヶ岳連峰、北アルプスの全容が眺められてすばらしい。山腹にはスキー場が開設され、山麓は一大別荘地帯をなし、長野市民のレクリエーション地をなす。
