Mount Azuma (四阿山 Azuma-yama) stands at an altitude of 2,354 meters and is nestled on the border between Nagano and Gunma prefectures. It is recognized as one of the 100 Famous Mountains of Japan.
While many visitors typically start their journey from the Torii Pass when driving, this guide introduces the way to access the western side of the mountain via Sugadaira Kogen Davos, which is accessible by bus.
