Koganezaki Furofu-Shionsen Hot Spring is a single inn located on Koganezaki promontory in Henashi, Fukaura Town, Aomori Prefecture.

Its location at the foot of Shirakami Mountains further enhances the appeal of this hot spring.
History and Origins of the Hot Spring
The history of Furofu-Shionsen Hot Spring is ancient, beginning when local fishermen discovered hot spring water welling up at the seaside. The founding family, who were net merchants, opened the hot spring inn with the hope that many people could enjoy this precious natural spring. Today, they continue the tradition of being net merchants, directly procuring and offering fresh seafood from the sea.
The Greatest Appeal of Koganezaki Furofu-Shionsen Hot Spring | The Spectacular Open-Air Bath Integrated with the Sea

From the open-air bath, you can enjoy the magnificent panorama of the Japan Sea spread before you. Bathing while feeling the sea breeze and listening to the sound of waves is truly a moment of bliss.

Another major appeal of Koganezaki Furofu-Shionsen Hot Spring is the spectacular view of the setting sun sinking into the Japan Sea. The time when the western sky begins to turn red draws particularly large crowds of bathers.
