About 'Kamenoyu by HATAGO INN'
'Kamenoyu by HATAGO INN' inherits a public bathhouse long cherished by the local community and renews it into a hotel offering accommodation, dining, and relaxation.
As a new expansion of the hotel brand 'HATAGO INN,' which pursues enjoyment beyond just 'sleeping,' this property places 'hot springs' at the heart of the guest experience.
In addition to a flowing natural hot spring bathing facility, new amenities include a restaurant, library space, nap booths, and workspaces. The hotel proposes diverse ways to spend time, with the 'bath' as the starting point.
Warm up in the hot spring, refresh in the outdoor air. A stay to fully enjoy natural hot springs.
Indoor and Outdoor Rock Bath
The centerpiece of 'Kamenoyu by HATAGO INN' is its comprehensive bathing facility.
Both men's and women's areas feature large communal baths with natural, continuously flowing hot springs, with all bathwater replaced daily. The baths include cypress tubs, electric baths, bubble baths, open-air rock baths, open-air cypress baths, barrel baths, saunas, and cold plunge pools. After the sauna, guests can relax in a newly installed outdoor air bathing area. After bathing, unwind on tatami mats in the post-bath rest area. Additionally, nine private bathrooms are available for exclusive use without worrying about others.
Overnight guests may use the bathing facilities unlimited times during their stay, while local residents can use them as a public bathhouse.
