When all is said and done, a special characteristic of the Motta Kaigan Onsen is the hot spring. In 1998, Mainichi Newspapers (毎日新聞) showed that the Motta Kaigan Onsen was one of 5 onsen (Motta Kaigan Onsen, Horonai Onsen (幌内温泉 * closing) in Okushiri, Futamata Radium Onsen (二股ラジウム温泉) in Oshamanbe, Kunbetsu Onsen (薫別温泉) in Shibetsu and Usubetsu Onsen (臼別温泉) in Setana) with natural radium in Hokkaido. In Japan, Tamagawa Onsen (玉川温泉) in Akita prefecture, Arima Onsen (有馬温泉) in Hyogo prefecture, Masutomi Onsen (増富温泉) in Yamanashi prefecture and Misasa Onsen (三朝温泉) in Tottori prefecture were famous places of the radium hot springs. Especially, the radiation dosage (300 Sv/hr) of the Motta Kaigan Onsen was almost the same as the Tamagawa Onsen (one of most major places of the radium hot springs in Japan). The the radium hot springs are expected to treat leukemia and cancer and prevent the spread of the leukemia and the cancer.

There are 1 open-air bath that about 3 people can take a bath and 1 indoor bath that 5 people can take a bath at a small bathhouse. The sum total of the hot spring ingredients are 10.12 g. Hot spring ingredients have been deposited on the floor of the bathhouse, and those look like small Pamukkale in Turkey and are strange shapes. It is worth seeing. Now wooden boards are installed on edges of a bathtub, but there was not the wooden boards in olden day and the hot spring ingredients deposited on the edges of the bathtub, and bathers seemed to enjoy the great natural hot spring power.

The hot springs are sodium chloride spring, and are a little opaque and have salty sulfur taste and a little sulfur smell. Flowers of sulphur were floated on the surface of the hot springs and it reminded me of Futamata Radium Onsen. The hot springs are drinkable, too. When I drunk the hot springs, it tasted like soup stock. It seems to be effective for Chronic digestive diseases and Chronic constipation. This taste reminded me of Kawakita Onsen (川北温泉).

A view is great, and you can see everything on the open-air bath from a road. But few people walk on the road, so you do not worry about it. I felt comfortable while seeing the Sea of Japan and enjoying a sense of openness. Shampoos and body soaps are provided at the bathhouse. There is not a restroom at a dressing room, so you should get a wash beforehand at the restroom at a corridor.
