Opening in August 2025! A resort space for people and their dogs to relax with a pool, sauna, and campfire.

Escape the hustle and enjoy a special time to unwind—together with your family, friends, and beloved dog. Surrender to the private pool and fully reset in the sauna. At dusk, gather around the bonfire; at night, enjoy a barbecue with your loved ones. And to end the day, soak in a Goemon-style bath while gazing up at the stars—. This is an entire private villa reserved just for you. Enjoy a luxurious stay with complete privacy.

  • As a newly opened Accommodation starting in 2025, everything is spotless and beautifully maintained. There are three bedrooms: two Rooms with two bedrooms each, plus one modern tatami Room in white and brown. The bedrooms also come with a projector and WiFi.The garden is enclosed by an aluminum fence, and with few neighboring houses nearby, it feels wonderfully private. The pool is clean as well, and it’s lit up at night for a great atmosphere. The BBQ Facility in the garden has a roof and vinyl curtain-style walls, so you can use it even in rain or wind. There’s also lighting, and heating installed under the roof, making it comfortable at night or during colder seasons.A washer-dryer is provided—having no piles of laundry after the trip was a huge help. Towels are also available.It was our first villa stay, and it exceeded expectations—an outstanding Accommodation with everything we needed.

  • We stayed with two families and two dogs.With the Plan that allows check-in from 12:00, we could start a barbecue from lunchtime, which was fantastic.Being able to check in three hours early felt like an even better deal than we expected.In the garden, surrounded by birdsong, we enjoyed the sauna and pool and relaxed on reclining chairs—an amazing way to recharge.The Facility is less than a year old, well maintained, clean, and comfortable throughout our stay.Our dogs also had plenty of space to run freely in the large dog run, making it an ideal environment for guests traveling with pets.It was such a wonderful place that we’d love to visit again.
