Tosa Ryu Onsen Sanyo-so

Kochi Prefecture/Tosa

20 minutes by car from Tosa IC, relax in our sodium-calcium chloride hot spring.

  • This is my second stay and my third time soaking in the Onsen.More than any Onsen I’ve visited before, the water quality and temperature suit me perfectly, and all my fatigue and stress melt away. If it were closer, I’d love to visit more often, but unfortunately I can’t.I’m very satisfied with both the meals and the staff.

  • It’s been a while since I stayed somewhere that helps carry your luggage. (LOL) The service was polite and great. As for the meals, given the price I didn’t expect them to be like the photos, but they really were—especially the sashimi platter with a big spiny lobster, which was delicious and very satisfying. The building and Facility are a bit old, but the location is right by the beach so you can go for a walk, and I was very happy with breakfast while looking at the sea and the footbath!
