Lake Usui

Lake Usui is a man-made lake in Gunma prefecture that dams the waters of Usui River and Nakao River. The lake has a circumference of 1.2 kilometers, and the walk around it is amazing. The area is abundant in nature, and is especially stunning in the autumn when the leaves on the trees change colors.
Meganebashi Bridge, the bright, vermillion bridge spanning across the lake, is a popular photo spot. This brick bridge was made in 1892, and is the largest arched brick bridge in Japan. The bridge is a great place to take a breath during your hike.
