Koganesaki Furofushi Onsen

Release yourself from the ordinary in this gourd-shaped seaside open-air bath!

Koganesaki Furofushi Onsen is a seaside hot spring featuring an open-air bath looking out onto the sea. Indulge in an exceptionally luxurious soak in this open-air bath while enjoying the dazzling view of the glowing sunset over the sea. Day visits are available until 4pm however an overnight stay is recommended to enjoy this stunning sunset view along with the excellent local seafood served for dinner!

Besides the gourd-shaped open-air bath open for mixed bathing, a separate round open-air bath for women is available. All four baths on site are filled with hot spring water flowing directly from its source.

The name Furofushi Onsen comes from the local saying “anyone who enjoys the health benefits of this hot spring will never grow old”. The dark brown hot spring water appears bottomless due to its high iron content. The distinctive brown water is so rich in iron and salt that it will keep warming your insides for hours afterwards!
