Lake Tazawa is a lake located in Semboku City, Akita Prefecture, Japan. It is the deepest lake in Japan and the 17th deepest lake in the world. The cause of the lake is not yet known. The area is 25.8 square kilometers, the deepest point is 423.4 meters, and the average water depth is 280.0 meters. In 1987, Chengcheng Lake was established as a sister lake with Niaosong Township, Kaohsiung County, Taiwan (now Niaosong District, Kaohsiung City).
Quite a good place to visit, with a beautiful environment and rich cultural atmosphere. It is worth a visit.
After walking through many places, Tianze Lake really makes this trip worthwhile, and it feels like a fairyland on earth. Cycling around the lake takes two and a half hours. Along the road, there are signs showing the names of farmers in nearby villages, bear-infested signs, and tall tall trees. The lake is crystal clear, and you see a little bit of garbage, and there is a green, blue, and dark blue change. The three people rent a bus and rent a car for a total of 3,500 yen. Highly recommended!
