Crystal-clear waters among the best in Boso! Enjoy seamless access to the pool in your swimwear! 【All rooms with ocean views】

The majestic Pacific Ocean is just a 0-minute walk away! Only a 10-minute drive to Kamogawa Sea World! Enjoy both the rocky shores and sandy beaches with exceptional water clarity, as well as the pool, all accessible in swimwear on foot. This all-ocean-view Hotel is perfect for exploring Boso and Kamogawa or simply enjoying the sea. At our buffet, don't miss our highly recommended seafood feast "Original Nokkedon"!

  • We visited Kamogawa Sea World for my daughter’s birthday and stayed at this Hotel for one night. We were looking forward to the dinner and breakfast buffets, and they were more luxurious than we imagined—we enjoyed plenty of sashimi and sushi. The sea bream kamameshi was so delicious I wanted a second serving.My daughter was very satisfied too, as she could eat lots of her favorite dishes. The breakfast croissants were also tasty. From our Room we had a panoramic view of the ocean, and the sound of the waves was soothing. The Onsen we enjoyed together left our skin smooth and felt wonderful. After returning home, my daughter and I talked about wanting to stay again.

  • We stayed with our 3- and 1-year-old children.The baby bath, baby shampoo, and diaper disposal bin were provided, which was extremely helpful.There was also a weaning food corner.As soon as you go down the Hotel stairs, you’re right by the sea, so the kids were absorbed in exploring the tide pools.It was great that there was a foot-washing area and tide-pool play gear available.All of the staff here were very kind to us.The Onsen water felt a little hot.
