About this facility
Kobayashi Onsen Bijin-no-Yu is a natural free-flowing hot spring in Kobayashi, Miyazaki Prefecture. Its sodium bicarbonate water is highly concentrated, with roughly 3,370 ppm of bicarbonate ions, and it is one of the 88 stops on the Kyushu Onsen-do bathing route. The indoor bath has a two-level tub at differing temperatures plus a mizuburo (cold plunge), while the open-air area features a goemon-buro (iron cauldron bath) with lukewarm water and reclining baths. The signature "Forest Log Sauna" offers self-loyly (water poured on hot stones) using the provided fans and herb-infused water. There are also nine fully private family baths, plus dining and ground golf.
