[update] Furusato Kanko Hotel filed for bankruptcy and Kagoshima District Court accepted their filings on Oct 2, 2012. The hotel was closed down end of Sep.
The mysterious Ryujin-buro (Dragon God Bath) is usually crowded during day time.
Furusato Onsen is located south of Sakurajima, an active volcanic island in Kagoshima City, Kagoshima Pref, in Kyushu Island. Furusato Kanko Hotel is known for its Ryujin-buro, a scenic open-air mixed bath faced on Kinko Bay.
The word Ryujin stands for "Dragon God", and there is a shrine just beside the bath. You have to wear white Yukata (Kimono) to soak the bath regardless your gender (For the Quick Movie and Photo Gallery, see their official site). Because it's supposed to be rude to show your body to the god. Apart from onsen pools, it's one of the very rare "clothing necessary" onsens.
You'll see many small stone statue under roots of the Ficus wightiana. The tree is more than 200 years old.
Although the sodium hot spring is clorinated and circulated (hot spring water is being reused), I could recognize mild touch of the onse water. There are gender separated indoor baths, and private baths, too.
Please note "Ontake", the volcano in the Sakurajima Island is very active, minor explosion counts more than 700 times in a year recently, and sometimes they have to close the Ryujin-buro due to volcanic ash.
