The Tamagawa River system's distinctive cobalt blue water surface

Shuusenko(Yoroihata dam lake)

Lake Akiogi spreads along National Route 341, and it shows a beautiful contrast especially during the autumn foliage season. The dam park located halfway up has a wonderful view. From Shin-Tamagawa Bridge upstream of the lake, you can see a submerged forest during times of high water and a marsh-like landscape during times of low water.
