Mt. Shirane, located at the midpoint of "Shiga Kusatsu Route(Route292)" connecting Kusatsu and Shiga, is an active volcano with an altitude of 2161 m, and the crater lake at the summit is Yugama. This lake is a beautiful emerald green crater lake with a diameter of 300m and a depth of 30m. Yugama is an acid lake with the highest concentration in the world, PH1.2, and it is hard for fish to live in. Yumi pond and moors created by the eruption of Mt. Shirane spread out nearby, and seasonal scenery and flowers add a touch of color to the surrounding scenery. It is a popular outdoor recreation area that offers hiking in the spring and summer, autumn colors in the fall, and skiing in the winter. There is an observatory on the south side of the lake, and the view from here is wonderful. The easiest and most popular walk is from the Shirane Resthouse to Yugama Crater Lake. It takes less than 10 minutes along a paved trail, and you will often see women doing it in high heels. At the top, you are rewarded with views of the sulfurous, baby blue Yugama Crater Lake as well as the surrounding mountain ranges.

Advice:
"Shiga Kusatsu Route(Route292)", which passes through here, will be closed in winter (End Oct-End April). Also, depending on the condition of volcanic gas, it may be closed even in summer.
