Sayama Lake
Lake Sayama, which straddles Tokorozawa City and Iruma City in Saitama Prefecture, is an artificial lake constructed for the purpose of securing water sources. As an irreplaceable dam lake for the region, it has been selected as one of the 100 best dam lakes.
The scenery by the lake is beautiful, making it a great place for a walk. If you time it right, you can even see Mt. Fuji in the distance at sunset.
