A clarity that seems to draw you into its depths

Yasui Valley is an attractive valley with breathtakingly beautiful natural scenery along the Yasui River, a tributary of the Niyodo River.
The scenery woven together by the emerald green pools, cascading waterfalls, and towering giant rocks fascinates visitors, who will feel as if they have wandered into a painting.
In particular, the crystal clear waters of the Yasui River, known as “Niyodo Blue” for its clarity, captivate the hearts of those who see it.

At Yasui Valley, visitors can enjoy beautiful sights across all four seasons.
Fresh greenery sprouts in spring; cool, refreshing greenery grows thick in summer; autumn leaves color the mountains in autumn; and snowy landscapes create a dreamlike atmosphere in winter.
Among the valley's sights, the characteristic appearance of Hiryuu Falls, a two-tiered waterfall with a 30m drop which looks like dragon twisting its body and flying away, attracts many people.
The mysterious beauty of the crystal pools, which change color to blue or green depending on the light, will also fascinate visitors.

There is a walking trail in the valley, where visitors can enjoy a stroll while taking in the beautiful scenery.
However, it is recommended that visitors wear comfortable walking shoes as the footing is poor n some areas.
Also, the trail may be closed due to weather conditions, so it is advisable to check in advance for peace of mind.
