Last update :

This enormous onsen ryokan is located in the Nanki-Katsuura onsen near the World Heritage Kumano-Nachi Taisha shrine. The complex consists of four buildings: the main building, the Nisshokan, the Sanjokan, and the Nagisakan, and accommodates 404 guest rooms; it’s one of the largest hotels in Japan.

The entire Noroshi Peninsula, which separates Katsuura Port from the Pacific Ocean, is the home of the ryokan. A turtle-shaped shuttle boat connects between the ryokan and the port. A shuttle bus is also available from the parking lot. (Only shuttle bus service is available on days when the shuttle boat does not operate.)

The biggest attraction here is the two large natural cave baths named "Boki-do" and "Genbudo.” These beautiful baths are built in wild natural caves created by erosion and offer a magnificent view of the Pacific Ocean. The spring water contains sodium chloride and calcium chloride. A huge volume of spring water flows into the five large baths, including the cave baths. An activity to collect stamps from each bath site is held to encourage guests to visit as many baths as possible.

Katsuura Port is a tuna town that has the largest catch of fresh tuna in Japan. A tuna cutting show is held at the buffet dinner, and guests can savor as much freshly cut tuna as they want. A kaiseki meal plan is also available for guests staying in the Sanjokan.
