[Limited to 12 groups per day] 90 minutes from central Tokyo, just 2 seconds to the sea. A hidden Accommodation still undiscovered. All rooms feature an ocean view and a private open-air bath.
The Pacific Ocean stretches out before you, accompanied by the gentle sound of waves in the stillness. Savor a refined moment with fresh seafood such as spiny lobster, splendid alfonsino, and abalone. As vast as the sea itself, your mind begins to unwind. Experience exceptional relaxation with all five senses in a luxurious retreat just beyond the city. An adults-only Accommodation featuring ocean-view rooms, each with a private open-air bath.
The car navigation directions weren’t very helpful, so I called the Accommodation for guidance. They kindly explained everything, and I arrived safely. The Room was clean, and I was able to relax while enjoying an ocean view from the bath. Every dish was delicious, and I was completely satisfied with both dinner and breakfast, including dessert. The late-night snack was also great. The tasty coffee was a nice touch.Spending time leisurely watching the sea up close was truly soothing. This is an Accommodation I’d love to return to.
tedma 8/14/2026I use IKYU about once a month, and this Accommodation is one I would definitely like to visit again.\nIt was reasonably priced, close to the sea, and the Onsen and meals were the best I have experienced so far.
