This is not the ruin of ancestors in Hokkaido. This is only one hot spting spa that has the quality of strong alkalinity. Once you soak in the hot spring bath, the surface of your skin turns slick and the extra horny layer will be melted and taken away.
Two ways are there to access to the spa but one of them can not be used because of the landslide after eavy rainfall around this area.
The entrance of the approach is on e way to Tomuraushi hot spring bath area from Obihiro City.
Please try it during your sty in Hokkaido and check it up at http://osoushi.foodsnet.net/
