What is Cambrian no yu ...

Japan's oldest stratum "Cambrian stratum" discovered around Hitachi City is considered to be the core stratum of the creation of the Japanese archipelago. During this period, when a wide variety of creatures appeared, it was called the "Cambrian Explosion" and was full of energetic power. It nurtures the lifestyle and culture of the people of this region and continues to this day.

Since ancient times, there have been "Kajime-yu," "Shio-yu," and "Yakiishi-no-yu," which utilize marine resources, as hot springs to entertain customers. At the hotel, you can enjoy the ancient hot springs that have been revived in the present age.

While listening to the sound of the sea, entrust yourself to the soft water.

The secret to moisturizing the skin is
Clean seawater and biting minerals.

Ecklonia cava

In the past, fishermen warmed their cold bodies by putting the seaweed "Ecklonia cava" from the kelp family from Mizukihama in hot water. Ecklonia cava extract is a fascinating amber-colored water that is rich in minerals and makes the skin smooth and difficult to cool.


We use high quality seawater from Mizukihama, which has been certified as one of the "100 Best Beaches". Since ancient times, salt production has been popular, and it has been popular with Shioyu customers as a hot water that is effective against all diseases due to its high salt concentration.


Yakiishi no Yu

This is our patented style bath. The ball gravel and salt steam also bring a warming effect to the whole body. The feeling of exhilaration after bathing in negative ions is exceptional.
