Q&A

All Earthboat properties are fully pet-friendly. Pets of any breed, size, or number are welcome with no restricted areas. Please see our Pet Policy for details.

We provide towels (bath and face), shampoo, conditioner, body soap, toothbrush, and hair dryer. For sauna use, we also offer outdoor sandals, swimwear, ponchos, and Löyly aroma oil.

Each room has its own outdoor living area with a firewood-burning fireplace. Firewood for both the sauna and campfire is prepared in advance — enough for one night's stay.

Check-in is from 15:00, and check-out is by 10:00 (may vary by property — please check each property's page). Late check-out until 11:00 is available as an add-on at Kurohime and Nasu and Ueda Onsen and Kitakaruizawa.

Each guest room is equipped with a kitchen, cooking utensils, and a refrigerator, allowing you to bring your own food and drinks and cook your own meals. A BBQ grill is also available in the outdoor living area.

Furthermore, meal options are available at each location, and unmanned shops are available at the Kurohime, Nasu, Hakuba, Ueda Onsen, and Kita-Karuizawa locations.

All rooms are equipped with a private sauna with adjustable temperature, along with a cold bath and outdoor relaxation space.

As these are private saunas, guests who may be restricted at public facilities — such as children and pregnant guests — are welcome to use them.

At locations other than Saitama Kawashima, the maximum occupancy is 3 people per room (1 queen bed, 2 extra futons). At Saitama Kawashima, the maximum occupancy is 4 people per room (1 double bed, 2 extra futons).

Children's rates: Preschool children (0-6 years old) are free of charge.
