Azumayasan - Azumayasan

A cone-shaped volcano towering over the border between Gunma and Nagano prefectures. It is also called Mount Azuma. It is 2,354 meters above sea level. It is said that this name came from the shape of the mountain, which resembles a roof. As it has a good view, two shrines dedicated to the border deity are enshrined on the summit. The border between Joshu Shrine, which faces east, and Shinshu Shrine, which faces west, is located in the center, north-south, on the border between Joshu and Shinshu. The mountain is mainly andesite, with a wide base. The southeastern foot of the mountain is part of the cabbage cultivation area of ​​Tsumagoi Village, the western foot is the highland vegetable cultivation area of ​​Sugadaira in Shinshu, and Torii Pass is located on the southern foot. The mountain ridge continuing to the south is also home to Matoiwa, a national natural monument. It is a three-hour walk from Torii Pass.

群馬・長野県境にそびえるコニーデ型の火山。吾妻山(あがつまやま)ともいう。標高2354メートル。山容が屋根の形に似ているのでこの名が出たという。見通しがきくので、山頂に二祠(し)の境界神が祀(まつ)ってあり、東に向かう上州祠と、西に向かう信州祠との中央の南北の方向が上信の国境になっている。山体はおもに安山岩で、裾野(すその)が広く、南東山麓(さんろく)は嬬恋村(つまごいむら)のキャベツ栽培地の一部、西麓は信州菅平(すがだいら)の高原野菜栽培地、南麓に鳥居峠(とりいとうげ)がある。また南に続く山稜(さんりょう)には国の天然記念物の的岩(まといわ)がある。鳥居峠から徒歩3時間。
