Ratings   (explanation of our rating system)

Global rating :   
Located close to the lake, this onsen use the cold water of that lake to cool down the temperature of the bath. The bath and the surrounding are really nice, but nobody bathed there.

Size :     
Quite a large rotenburo.

View :     
A very nice view on the lake - just a couple of meters from the bath. Unfortunately, there is also a nice view on the parking...

Modesty :  
Unless you wear a swimming suit, you probably will never bath in Wakoto Onsen! The place is really opened toward the car parking, and many curious and fully clothed people come near the bath to check the temperature...

Area :     
Lake Kussharo is a beautiful caldera lake located in Akan National Park. With a circumference of 57 kilometers (maximum depth of 118 meters), it is the 5th largest lake in Japan. The Wakoto peninsula is one of the nicest place around the lake, with one free rotenburo). Boat, canoes and kayaks can be rented, and are popular in summer. In winter, the lake might freeze. Close to Lake Kussharo, the town of Kawayu Onsen is a typical uninspiring japanese onsen town, which lacks the beautiful view of the nearby lake. Mt. Iou can easily be reached, and is an active 500 meters high volcano, where acid smokes and solid sulfur can be observed. Finally, the most attractive place of the area is probably Lake Mashu, a beautiful and mysterious lake with a tiny island, where Ainu gods were supposed to live; This island rises 230 meters from the bottom of the lake. The shore of the lake is kept completely wild, and only three observatory points are available. Be aware that most of the days, the lake can be hidden from the viewers by a very dense fog.


We visited this bath three times, including once during the night, but we never could see anybody bathing there...



Many visitors just come fully-clothed near the bath... discouraging people to soak in this onsen
