Access by boat from the port! Enormous onsen ryokan with large cave baths.
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.

You actually take a shuttle boat to get to the hotel, and there are two cave baths to choose from! It's such a unique experience. I highly recommend staying here if you get the chance.
Hotel Urashima is right across from the pier! It was my first time staying at an onsen hotel where you have to take a boat to check in—so cool!!
If you visit Japan, you have to stay at the Katsuura Onsen Hotel! What impressed me most is that the whole island is the hotel, and the hot springs are built inside natural caves! The hotel is right on the coast of Kii-Katsuura in southern Wakayama. I really love the hot springs here. ♨️❤️
You actually take a cute little boat to check in at the hotel! There are several buildings and lots of different hot spring baths. The colored signs on the floor help you find your way—otherwise, it's easy to get lost.
