Relax with breathtaking ocean views and fresh seafood cuisine.
All rooms feature ocean-view Japanese-style accommodations with breathtaking scenery. Relax and unwind in the Onsen large public bath with an open-air bath. Enjoy fresh seafood dishes made from locally sourced ingredients, as well as a cypress wood private bath. The spacious Japanese-style rooms are perfect for individuals or families. We also offer an all-you-can-eat service, including a grand sashimi platter and desserts.
My parents, both over 80, love crab, so we visited mainly for the crab buffet. The meals were great—not only the crab, but also a wide variety of dishes, especially at breakfast. The bath was also wonderful; it was nice to soak in a hinoki bath. We requested a Japanese-style Room plus an additional 4.5-tatami area, but the 4.5-tatami space was located right by the Room entrance and wasn’t very usable, which was disappointing. In that case, a standard Japanese-style Room would have been fine. All staff were cheerful, kind, and pleasant. The baths also seemed to have been renovated or renewed, and it felt like the Hotel is making a strong effort overall, which I appreciated. This time we were able to use a coupon on Yahoo Travel and I think we probably got the best price available. When I explained that we were traveling with two elderly guests, they kindly arranged a Room with easy access to both the bath and dining area, which we truly appreciated.
Yahoo!トラベルユー... 7/18/2026This was my second stay.Last time I visited during the beach season, but this time I stayed in March.With prices rising everywhere lately, it’s been tough, so I’m very grateful that Taiyo is such a reasonably priced Accommodation.However, last time sashimi was served at breakfast, but this time it wasn’t...I was a little disappointed, but everything else was great and I was very satisfied.Thank you very much to all the staff for your hospitality.
