A seaside cottage designed with the concept of providing a comfortable and enjoyable space for you, your beloved dog, and your family by the Dog Hotel owner. Meals can be catered, prepared in the kitchen, or enjoyed as BBQ. Wake up to a morning filled with abundant light and create unforgettable moments with your precious family. Cats are also welcome.

Multiple Night Stay Plan bookings are available for early booking 6 months in advance. *Please set the number of nights to "2 nights" or more to check availability.

  • Whenever you visit, you can count on peace of mind, safety, and exceptional cleanliness. If it makes people feel their best, it’s sure to be just as satisfying for dogs. No matter how many times we go, we’re always completely satisfied. -

  • We stayed for a multiple night stay with our senior dog. Being right in front of the ocean, you can enjoy the view of the sea from the second-floor room or while soaking in the bath. Above all, the room was completely odor-free and impeccably clean. Having stayed at numerous accommodations ranging from budget-friendly to luxurious ones with our dog, I can confidently say this place ranks top in cleanliness. Even though it’s not a newly built accommodation, maintaining such cleanliness must require tremendous effort, and we are truly grateful for that.Although it rained during most of our stay, it cleared up on the last day, allowing us to take a walk with our dog by the ocean before checking out. The Minami-Boso area has places where you can dine with your dog, and since we could also order delivery at this accommodation, we would love to visit again!
