Ja-Ishi (Snake Stones)

Ja-Ishi is an unusual rock formed from layers of slate, intruded by metamorphic rocks. It is designated as a national nature treasure. It is called Ja-Ishi (snake stones) because the figure lying at great length in the river bottom, showing its white stripe pattern looks just like a large snake.

In summer, it is popular as a campsite. The visitors can enjoy a beautiful sight of red Japanese maple leaves in autumn. A great view of snow ice is also wonderful in winter.
