Very small thermal spring on the lake shore where, with a little attention to the slippery bottom, it is possible to get wet. Wooden changing cabins available, although in poor condition. A little corner of paradise.
Perfect for a sunny Spring day. It’s a wild onsen so expect algae. Very few people there even during GW
Very nice view with onsen water flowing out to the lake. But when we visited, lots of algae floating around and surrounding ground was muddy. No shower facilities just 2 simple separate changing rooms for female & male. Free parking right at the onsen.
