An outdoor style tent sauna that dives into the vast ocean.
The main attraction of Beach Sauna is the water bath in the Seto Inland Sea.
The "water bath where you can swim" Seto Inland Sea becomes a threatening single room (water bath below 10 ℃) in the middle of winter.
Since it uses Morzh that warms the inside of the sauna to 120 ℃, it can be enjoyed by a wide range of people from authentic saunas with a temperature difference of 100 ℃ to sauna fans who like extreme experiences.
It is limited to one pair each time, so please fix your tired body in the private sauna space.
Seto Inland Sea Hidden Resort "Limited plan for hotel guests" and "one day use only plan" are available.
If you are staying at the Setouchi Hidden Resort, please make a reservation here. Please write the "reservation number" of the Setouchi Hidden Resort Accommodation in the "Remarks" when you make a reservation.
Please note that the time may change depending on the situation on the day.
