10 seconds to the beach, a hub offering nature and seafood.

Just 10 seconds to the beach, this Property is surrounded by stunning nature and abundant seafood. Enjoy an open space and moments of relaxation as you wish. Additionally, we offer Western-style and Japanese-style Rooms where you can stay with your pets. Savor fresh sashimi from the local fishing port in your Room while listening to the soothing sound of the waves.

  • First, I was truly impressed by the wonderful view from the Room!The meal wasn’t a large set (assorted sashimi, small side dishes, rice, and soup), but the sashimi was fresh and plentiful—I think most women would feel full.The staff were kind and kept a comfortable distance.The Hotel itself may not be new, but it felt clean, and even the pet-friendly Room had no noticeable odors.There is no large public bath such as an Onsen, but there are showers where you come up from the beach, so I think it’s also great for summer—so I made another Reservation for summer.I look forward to staying again.

  • With windows spanning an entire wall, this is an outstanding location with nothing but the ocean in view.There was no noise from upstairs, downstairs, or neighboring Rooms, making it very comfortable. We were also surprised by the large TV—Netflix is available too.Plenty of amenities for dogs as well.It was a bit disappointing that the windows can’t be opened and there’s no large public bath, but the in-Room bath was still very comfortable.We’d love to stay again.
