Yunoko Lake

Yunoko Lake is a tranquil mountain lake formed by volcanic activity. This small but scenic lake sits at an elevation of 1,478 meters and covers an area of about 0.35 square kilometers. The lake's name, Yunoko, translates to "hot water lake," hinting at the nearby hot springs that feed into it.

Yunoko Lake was formed around 20,000 years ago when Mount Nantai erupted, creating a natural dam. The lake’s waters are crystal clear, reflecting the surrounding mountains and forests. It's especially beautiful in autumn when the trees around the lake turn brilliant shades of red, orange, and yellow. The lake is famous for fishing, with species like rainbow trout and Japanese char in its waters.

At the northern end of the lake, you’ll find Yudaki Falls, where water cascades down 70 meters, adding to the area's natural charm. The peaceful environment around Yunoko Lake makes it a great spot for walking, with trails that offer stunning views of the lake and the surrounding landscape.
