Hot Spring Large Bath Rooms / Guest Room Baths / Private Open-air Baths (2 types)

All bath rooms look out over the Sea of Japan. The large bath rooms (both indoor and open-air) are located on the second floor, and the private open-air baths (reservations required) are outdoors. The open-air bath attached to the large bath room is fed by the thermal waters of Aikawa Hot Springs, and the private open-air baths are fed by Sado deep-sea water. The waters have a reputation for helping recovery from fatigue, as well as beautifying skin. Have a good soak and relax while looking out over the powerfully lapping waves of the Sea of Japan.

Hotel Azuma is nestled on the tip of the cape. All you can see is the sea; there are no obstacles or artifacts such as tetrapods, and it is impressive to see the white-topped waves crashing against the Hokake-iwa Rock right before your eyes.
The private bath rooms with a magnificent view of the sea stand on a vast lawn of approximately 23,000 ㎡ (one of the largest hotel sites in Sado) within the scenic Sado Aikawa Nanaura Kaihin Quasi-National Park.
