Ookama Onsen is a hot spring housed in a reconstructed school building. The Nyuto Onsen Primary School Ookama Branch sign humorously stands at the gate and the school hall and staff room remain intact giving visitors nostalgic memories of childhood. The hot spring inn offers free foot baths at the entrance for trekkers and day visitors during summer.

An open-air bath surrounded by green forests offers rustic comfort to visitors, while the interior wooden baths are filled with an atmosphere of yesteryear. The Onsen consists of yellowish hot spring water with fluffy muddy mineral-rich sediments. A natural mud mask can be applied to the face and body to promote beautiful skin.

After a warm hot spring bath, enjoy the traditional refreshment of an old-fashioned bottle of cold milk! Regional dishes with excellent freshwater fish and wild vegetables are a popular treat!

Day visits are available, Onsen hopping at Nyuto Onsenkyo is said to be beneficial for all kinds of ailments.
