Noboribetsu Grand Hotel Day Use: Onsen Hours, Price and Oni Sauna Days
Noboribetsu Grand Hotel day entry is ¥2,000; check whether the Oni Sauna is on the women’s odd-date or men’s even-date schedule.
The main planning question is not just whether the hotel has an Oni Sauna; it is whether the right side of the bathhouse is assigned to you on the day you visit. The hotel’s current day-use page says the Oni Sauna changes between men’s and women’s sides each day. Its published rule is women on odd-numbered dates and men on even-numbered dates.
Check your date before heading to the hotel
The day-use Oni Sauna is in Hozuki-no-yu. Since the bath assignments alternate, a woman visiting on an even-numbered date should not expect access to that side, and the reverse applies to men on odd-numbered dates. The rule is based on the date number, not the weekday. Temporary maintenance or changes to reception can still override the normal schedule, so check the hotel’s notices on the day.
This date check matters most if the sauna is the reason for choosing Grand Hotel. If you mainly want the garden baths or a range of Noboribetsu spring waters, the visit is less dependent on the parity rule. The hotel lists day-use access to three spring types: saline, iron and sulfur.
Hozuki-no-yu has both the Oni Sauna and Seiryu Sauna; Rindō-no-yu has the Kuma Sauna. The odd/even schedule decides which side you enter, so a day-use ticket does not give one guest access to all three saunas at once. Maintenance notices or temporary reception changes can override the usual schedule.
Current day-use hours and admission
The hotel currently lists two admission windows:
- Morning: 7 a.m.–10 a.m.; last admission at 9 a.m.
- Afternoon: 12:30 p.m.–8 p.m.; last admission at 7 p.m.
On Mondays and Thursdays, afternoon admission starts at 2:30 p.m. Admission is ¥2,000 for adults (junior high school age and older) and ¥1,000 for children aged two through elementary school. The hotel warns that daily conditions can lead to suspended admission or shorter hours, so an old itinerary is not a guarantee that the baths will be open as usual.
The morning window is useful if you are travelling through the resort before lunch. The afternoon window leaves more room for a walk around the hot-spring district, but arriving after the last-entry time will not work even if the hotel remains open to guests.
What the day-use ticket is for
Grand Hotel pairs its indoor Roman-style bath with garden open-air baths. The facilities include separate bathing areas for men and women, and the date rotation determines who can use the Oni Sauna on a given day. Do not read the sauna’s headline temperature or design as a promise that every day visitor can enter that side.
If you want two people to share a private bathing space, the hotel also lists one reservable family bath. It costs ¥4,400 per 50-minute session, up to four people; day visitors pay the regular admission fee separately. Reservations are required. That is a different product from the public outdoor baths.
For two adults, the basic total is ¥8,400: ¥2,000 admission per person plus ¥4,400 for the room. Transport, food and any other spending are extra. The family bath uses saline spring water and is listed as source-flowing, but the hotel’s day-use information does not identify it as an outdoor bath. Do not assume a private session is included in the public-bath admission price.
The three natural spring categories in the public baths are saline, iron and sulfur. The hotel describes them as separate bathing options, but the information reviewed here does not identify three fully documented independent sources. Nor is every pool handled the same way: the large circular saline bath is described with continuous source-water input and circulation/filtration, while some smaller baths and designated garden outdoor baths are listed as source-flowing, with water or heat adjustment possible. There is no complete public set of current source temperatures or pH values to apply across the facility.
The Oni Sauna is listed at about 110°C, with automatic water release once an hour at 30 minutes past the hour. The Seiryu and Kuma saunas are listed at about 80°C. These are room settings, not spring or bath-water temperatures. The large outdoor barrel cold bath uses stream water rather than hot-spring water; the hotel limits it to guests aged 13 and over and operates it seasonally. Check the hotel’s current notice for its opening period before making a special trip.
A short walk from the bus terminal
From JR Noboribetsu Station, the local bus takes about 16 minutes to the Noboribetsu Onsen Bus Terminal; the hotel is about a one-minute walk from there. This is useful if you are travelling without a car or carrying luggage. Check the Noboribetsu access guide for the station connection and return bus.
The guide’s seven editorial ratings are bathing comfort 95, variety 95, upkeep 85, scenery 90, quiet 75, access 100 and value 90. They are comparative assessments, not scores published by the hotel.
Questions to settle before you go
Can a man use the Oni Sauna on an odd-numbered date? Under the published rotation, no: Hozuki-no-yu is assigned to women on odd dates. Men use the other side that day; the reverse applies on even dates.
Does the day ticket include all three saunas? No. The saunas are split between the two bathing sides, and guests enter the side assigned to their gender on that date.
Does ¥4,400 cover two adults’ admission to the family bath? No. The session fee is separate. Two adult day tickets plus the room fee currently total ¥8,400.
Is the family bath a private outdoor bath? The hotel lists a reservable family bath, but the day-use page does not identify it as an open-air bath. Ask the property if outdoors is essential.
For a lower-cost public-bath visit, compare Sagiri-yu and Dai-ichi Takimotokan. If your trip is partly about the outdoor trails, the Jigokudani and Oyunuma walking plan helps you leave time for the return bus; for a longer stay, see where to stay in the resort.
Noboribetsu Grand Hotel’s day-use and bathing pages give no general tattoo rule. If you plan to use the baths, contact the hotel before travelling to ask what its current policy allows.

Day-use reception and sauna assignments can change for maintenance or other operational reasons. Recheck the hotel’s latest notice before travelling, especially when the Oni Sauna is your main reason for going.
