Two rare types of natural hot springs
Open-air bath 'Kin Onsen' (Golden hot spring) has a salt concentration level similar to seawater, which is rare even in Japan.
It is said to be beneficial for conditions such as poor circulation, lower back pain, and muscle and joint pain.
The indoor bath 'Gin Onsen' (Silver hot spring) is also a rare carbonated spring, which is known for its moisturizing effects on the skin.
You can luxuriously enjoy these two rare types of natural hot springs while gazing at the sea.

The Kin Onsen is an open-air bath where you can enjoy a soak while gazing at the sea right in front of you.The Gin Onsen is an indoor bath adjacent to the Kin Onsen, allowing you to alternate between the two hot springs.
Open-air bath:Golden Hot Spring
Golden hot spring, which is rich in iron content, is initially colorless and transparent underground, but oxidizes to a reddish-brown hue upon exposure to air. It exudes a subtle scent of iron and offers a gentle, soothing touch with minimal irritation to the skin.
Enjoying the changing seasons and the sea right in front of you in the open-air bath, warm your body from the core.
