Oshio Lake / Oshio Lake boat

Oshio Lake is adjacent to Gunma Safari Park. Approximately 1,000 cherry trees, azaleas and other colorful flowers including hydrangea bloom on the lakeside. In automn, colored maple leaves on the mountains surrounding the lake reflect vividly on its surface. In winter, the surface of the lake wrapped in quietness carves the time going by.
