Introduction of the Accommodation
Nestled in the forests of Nasu, reset body and mind in an authentic Finnish sauna. A fully private, entire cabin rental.
Each guest room is equipped with an authentic private wood-burning sauna. After surrounding yourself in steam with self löyly, cool down in a cold plunge that lets you feel the forest air, then unwind outdoors for a blissful “totonoi” reset. In a space reserved just for you, enjoy a retreat that awakens all five senses.
Even large dogs are welcome on the bed. Enjoy a truly pet-friendly getaway with your beloved dog, surrounded by the fresh breath of the forest—no compromises.
Earthboat Nasu has no restrictions on the number, type, or size of pets. With a woodchip-covered outdoor living area and a design that lets you sleep in the bed with your dog, we put your stay together as cherished family first. Time in the terrace dog run or gathered around the campfire will be an unforgettable experience for your dog too. Deepen your bond to your heart’s content amid Nasu’s abundant nature.
Free Private Open-Air Bath “Kogetsu-no-Yu”
At Earthboat Nasu, we offer a private open-air bath available free of charge for all Room guests. Enjoy the sulfur hot spring water of Nasu Yumoto, continuously flowing directly from the source.
Private Guest Suite with Open-Air Onsen Bath
Guest rooms under the “Onsen Open-Air Bath Included Plan” feature a private open-air bath with Nasu Yumoto sulfur Onsen, the same as “Kogetsu-no-Yu.” In these rooms, you can enjoy both a wood-burning Finnish sauna and Onsen in complete privacy.
Earthboat Nasu is easy to access even without a car.
Earthboat Nasu is about a 10-minute walk from the nearest bus stop. From Tokyo Station, you can reach us in around 2.5 hours by Shinkansen and bus. Around JR Kuroiso Station, you’ll also find plenty of places to stop by, including the Nasushiobara City Library “Miruru” and the popular bakery “KANEL BREAD.” Even without a car, you can enjoy sightseeing in the Nasu area before and after your stay at Earthboat.
