Mt. Hayachine (早池峰山, 1,917 m) is the highest peak in the Kitakami mountains, straddling Hanamaki, Miyako and Tōno in Iwate Prefecture. Famous for the endemic Hayachine-usuyukisō (late-July bloom), it is a “100 Famous Flower Mountains of Japan” peak and one of Kyūya Fukada’s 100 Famous Mountains.
Within Hayachine Quasi-National Park, the mountain’s serpentinite ridges and rich alpine flora (200+ species, with many endemics like Nanbu-toranō and Nanbu-inu-nazuna) make it the “flower mountain”. The standard Odagoe course is ~700 m gain / ~5:30 round trip, intermediate, and one of Tōhoku’s most renowned flower mountains.
