Mt. Hayachine

Treasure trove of alpine plants,  one of the “100 Attractive Mountains of Japan.”Mt. Hayachine - 
mountain of the gods

One of the highest mountains in Iwate

The Mt. Hayachine area consists of several peaks, notably its 1917m-high summit, Kengamine to the east and Nakadake and Keitosan to the west, extending over more than 10 kilometers. Mt. Hayachine is the highest peak in the Kitakami mountain range, and is counted in the book, “One Hundred Mountains in Japan” by Fukada Kyuya (1903-1971).
The neighbors of the mountain, as well as the lord of the Morioka domain, felt deep reverence for it as a site of ancient mountain worship.
The appeal of this mountain lies in its various kinds of alpine flora, starting with Hayachine Usu Yuki So. Hikers are fascinated by such pretty flora growing and blooming in the harsh natural environment.
The area of this precious mountain and Mt. Yakushidake, a mountain south of Hayachine, is designated as a special natural treasure and a quasi-national park, and great care is taken to conserve its environment.
Although you can climb the mountain in a relatively short time, you should make a detailed plan and take enough equipment as conditions can become dangerous due to the weather.

The view from the top of the mountain is magnificent: a field of alpine flowers, a dense forest below, and the ridge lines of Mt. Yakushidake to the south. Around the summit, there are many oddly-shaped rocks which have become objects of religious faith. “Buchi Ishi”, located in the middle of the Kawara no Bo trail (see the picture above), has a folk story about a tengu (long-nosed goblin) that hit his head on this rock.
