Mt. Iwate (岩手山, 2,038 m) is an active volcano straddling Takizawa, Hachimantai and Shizukuishi in Iwate Prefecture. Its elegant cone earns it the names “Nanbu Fuji” and “Ganju-san“, and it is the iconic mountain of Iwate Prefecture, counted among the 100 Famous Mountains of Japan (Kyūya Fukada’s selection).
Its 7 trails include the Yanagisawa course (Umagaeshi, old / new routes), the Yakehashiri course (1719 lava-flow with great Komakusa flower fields), and the Amihari course from Amihari Onsen. The 8th-station emergency hut (free, capacity 50, blankets provided) is one of the best in Tōhoku, and the great Komakusa flower fields (mid-July to early August) plus the wide summit crater rim are the main attractions.
