Mt. Azuma (吾妻山, Nishi-Azuma 2,035 m) is a volcanic group straddling Yonezawa in Yamagata Prefecture and Fukushima City in Fukushima Prefecture, comprising the highest peak Nishi-Azuma, the active Issaikyō (1,949 m) on the Fukushima side, the iconic Azuma-kofuji (1,707 m), Higashi-Azuma and more — within Bandai-Asahi National Park, a 100 Famous Mountain of Japan (Kyūya Fukada’s selection).
The highlight is the cobalt-blue Goshiki-numa “Witch’s Eye” crater pond just below Mt. Issaikyō, plus the 30-minute crater rim circuit of Azuma-kofuji. The Bandai-Azuma Skyline reaches Jōdo-daira at 1,580 m by car, making the Mt. Issaikyō round trip accessible (easy ★★★/★★, ~4 hours). Mt. Nishi-Azuma is reached via the Tengendai Ropeway (Yonezawa side) or Grandeco Gondola (Inawashiro side) up to 1,820 / 1,390 m.

About the Azuma range
A volcanic group straddling the Yamagata-Fukushima border. The highest peak Nishi-Azuma (2,035 m) is on the Yamagata side, while Issaikyō (1,949 m, active), Higashi-Azuma (1,975 m) and the iconic Azuma-kofuji (1,707 m) sit on the Fukushima side, in Bandai-Asahi National Park. Fukada treats “Mt. Azuma” as a single 100 Famous Mountain; the Goshiki-numa “Witch’s Eye” and Azuma-kofuji’s crater are the iconic views.
Trail summary (3 patterns)

- Azuma-kofuji crater rim circuit (beginner, 30 min): from Jōdo-daira parking
- Nishi-Azuma course (Tengendai or Grandeco) (easy–intermediate, 4–6 h): Yamagata / Fukushima side, the summit attempt
