About Zao Onsen

Zao Onsen is a hot-spring village at about 900 meters elevation, on the western slope of the Zao range, southeast of Yamagata city. Its springs are among the most acidic in Japan, with sulfurous, milky water, and tradition says people have bathed there for around 1,900 years. The village has sloping streets, ryokan, shops and three public bathhouses, plus a large outdoor bath in a valley.

In winter, Zao Onsen is one of the largest ski resorts in Tohoku, with runs that descend from the top of Mount Jizo. It is there that the juhyo, the “snow monsters,” form: mountain firs coated by layers of ice and snow driven by winds from the Sea of Japan, taking the shapes of giant figures. They usually appear from January to February, depending on the cold and wind each year.

The Zao Ropeway cable car climbs from the village to the station on Mount Jizo, at about 1,660 meters, in two sections. In winter, the snow monsters stand around the station and on some nights of the season are lit up. In summer and autumn, the area has trails among alpine flowers and foliage, and a stone statue of Jizo at the top that is covered by snow in winter.

On the other side of the range, on the Miyagi side, lies the Okama crater, an emerald-green lake reached by the Zao panoramic road, which closes in winter. Access to the high areas of Zao depends on the volcanic alert level and the weather. On very windy days, the cable cars may stop.
