Mt. Azumaya

Mount Azumaya is one of the 100 Famous Japanese Mountains. The 2,354-metre-high peak lies on the border of Nagano Prefecture and Gunma Prefecture. There exist alternative spellings of the mountain's name, like: 吾妻山 and 吾嬬山 which is read as "Agatsuma-yama". In the village Tsumagoi, the mountain is spelled 吾妻山.

The mountain should not be confused with Mount Azumaya of which there are two, one in Nagano Prefecture and the other in Saitama Prefecture. Though the reading is the same, the name written in Kanji differs from the mountain in this article.
