A traditional Japanese-style Onsen resort perched on a cape overlooking the Atlantic Ocean, just a short distance from Senjojiki.

Nanki-Shirahama is one of Kansai’s leading resort destinations, offering both the sea and Onsen. Near Senjojiki, a renowned scenic spot in Shirahama, the new traditional Japanese-style Hotel “Hamachidori no Yu Kaishu” has opened on a cape jutting out toward the Pacific Ocean.

  • I finally got to experience this Accommodation I’d been curious about for a while, thanks to its appealing Instagram posts and high rankings online!In conclusion, it’s a wonderful Onsen Accommodation with a high level of satisfaction that truly lives up to the hype.The food is especially outstanding. At dinner—famous for its boat platter—you can enjoy Kishu-style whale dishes, along with a lineup of carefully prepared courses.As for the Onsen, it was a bit disappointing that every bath felt too hot to fully relax in,but you can still enjoy thoughtfully designed baths, including an open-air bath where you can feel the sea up close.I’m glad I found an Accommodation I’d love to return to in another season.

  • This was my first stay here. The property looks great, and the training of the international staff is excellent. The service was wonderful, and the food was truly delicious. The Room and the open-air bath in the Room were outstanding, allowing me to relax and unwind at a leisurely pace. If I have the chance, I would love to return with my family. Thank you very much.
