About Hatoko no Yu
Hatoko no Yu is a hot spring facility where visitors can look out over the sea in front of it, feel the sea breeze and listen to the sound of the waves. Large ships passing through the strait are also part of the view, so guests can take in the scenery and nature unique to Kaminoseki with all five senses.
Another attraction is the red-brown "Akayu" (red bath), pumped up from about 1,000 meters underground and rich in iron, manganese and minerals. The open-air bath in particular offers a sweeping view of the Kaminoseki Strait, a relaxing and open setting.

A natural hot spring right beside the strait.

The indoor bath uses "Hakuyu" (white bath), with manganese and iron removed.
More to Enjoy in Kaminoseki
Besides Hatoko no Yu, Kaminoseki has sightseeing spots suited to families, including the Kamimoriyama Observatory with its 360-degree view, Michi-no-Eki Kaminoseki Kaikyo with its fresh seafood, signature tempura and souvenirs, and the Shikairo, a nationally designated Important Cultural Property.
