Mt. Hayachine (1,917 m) is Iwate’s most sacred mountain — a rugged serpentine-rock massif supporting rare endemic alpine plants found nowhere else on earth. In July and August the summit plateau is carpeted in Hayachine usuyukiso (a unique alpine edelweiss relative), drawing botanists and hikers from across Japan.
