Ichinomata Onsen Grand Hotel Day Trip: Prices, Baths and Access
Ichinomata Grand Hotel charges ¥1,150 for day bathing and has a pH 10 sulfur spring, sauna and private bath. Its station shuttle is for overnight guests.
Ichinomata Onsen Grand Hotel is a good day-use stop if you are driving through the mountains of Shimonoseki and want more than a quick soak: the public bath has indoor and outdoor pools, a sauna and a cold plunge. Admission is ¥1,150 for adults and ¥600 for children aged three through elementary school. The trade-off is access. The free shuttle from JR Ozuki Station is for overnight guests, so it is not a day-trip solution.
The hotel’s alkaline simple sulfur spring is listed at about pH 10, and the property confirms that its water is filtered and recirculated. That distinction matters if you are choosing specifically for untreated, free-flowing water: the high pH does not make this a fully flowing bath.
The basic cost, including the towel
| Day-use item | Price or detail |
|---|---|
| Adult admission | ¥1,150 |
| Child admission, age 3 through elementary school | ¥600 |
| Face towel | ¥100 |
| Private bath | ¥2,000 for one hour, plus each guest’s admission |
| Parking | Free; about 100 cars |
Soap, shampoo, conditioner, body wash and hair dryers are available in the public bathing area. A face towel costs ¥100, so an adult arriving without one should budget at least ¥1,250. The current price list does not give a day-use bath-towel rental price; do not assume an overnight-plan price applies.
The hotel is currently advertising a ¥300 local coupon for day-use bathing through November 30, 2026. The wider campaign can end early if its issue limit is reached, so check availability before building it into your budget. Treat it as a temporary discount, not the admission price.
Check the calendar before choosing an arrival time
On ordinary days, day-use bathing runs from 8:00 a.m. to 9:00 p.m., with last reception at 8:00 p.m. Saturdays, public holidays, Golden Week, Obon and the year-end/New Year period usually have shorter hours: 8:00 a.m.–5:00 p.m., last reception 4:00 p.m. Group bookings and maintenance can change the schedule, and the hotel posts a monthly calendar.
The difference is large enough to shape the day. An evening arrival can work on a regular weekday; it is risky on a Saturday or holiday. Confirm the date-specific calendar before leaving, especially if this is a long drive.
The rest area, Ryokufuan, is open from 10:00 a.m. to 3:00 p.m. Food service runs 11:30 a.m.–3:00 p.m., with last orders at 2:30 p.m. That gives drivers somewhere to sit down after bathing, but it is a daytime option rather than a late-evening fallback.
What the bath ticket covers

The public area combines a large indoor bath with a garden-facing open-air bath, sauna and cold plunge. It is a more varied stop than a small local bathhouse, and the mountain setting is the point: the outdoor bath looks onto greenery and the surrounding valley, not the sea.

The hotel’s spring explanation gives a pH around 10 and classifies the water as an alkaline simple sulfur spring. Its FAQ says the hot-spring water is filtered and recirculated. The exact source temperature, fixed bath temperature and spring yield are not published in the current text pages. A reported spring pH also says nothing about the temperature of an individual pool; see the guide to reading onsen water temperatures and understanding Japanese spring classifications.
Private baths need a reservation
The two private baths returned to normal service on August 22, 2026, after repair and renovation. The former barrel bath is now the cypress Honoka; Yunoka is the stone bath.
A one-hour session costs ¥2,000. Private bathing is offered from 9:00 a.m. to 9:00 p.m., with last reception at 8:00 p.m. Day visitors also pay regular admission for each person.
Two adults therefore pay at least ¥4,300 before towels. It is a useful option for people who want privacy or cannot comfortably use separate men’s and women’s public baths together. Book ahead; arrival does not guarantee an available session. The public bath already has an outdoor pool, sauna and cold plunge, so the extra fee only makes sense if the private room itself matters.
The hotel lists admission prices for children, but the current main pages do not fully explain every rule for young children in the shared bath. Ask the property about the specific situation before travelling with a child who needs special arrangements.
Driving is practical; the train shuttle is not for day visitors
The hotel has free, unreserved parking for about 100 cars. It warns drivers against two tempting-looking approaches on National Route 491: do not head north from the Narasaki junction in Kikugawa, and do not head south from Shin-Ōbō junction in Yuya-Kawara. Both stretches become narrow and are described by the hotel as dangerous. Follow the recommended approach rather than the shortest line offered by a navigation app.
The free shuttle from JR Ozuki Station takes about 40 minutes, but it is explicitly for overnight guests and must be booked by the previous day. Its listed trips—outbound at 4:00 p.m. and return at 9:45 a.m.—are not a usable day-trip connection.
Yamaguchi tourism information lists a bus ride of roughly an hour from Ozuki, but the exact stop, service and return connection need to be checked for the travel date. Without a car, a pre-arranged taxi may be the more workable option; confirm both legs and the fare before setting out.
When this stop fits—and when it does not
Choose the Grand Hotel when you already have a car, want a mountain-valley bath with several facilities, or can make use of the daytime rest area. Allow around 90 minutes to two hours for the shared baths; add more time for lunch or a private session.
For a lower-cost bath with a simpler day-use setup, compare Peaceful Seiryusen in Kawatana. If you are deciding between the two Ichinomata sister properties, the Grand Hotel vs. Kanko Hotel comparison separates their day-use prices, bath facilities and access. Other useful stops in the wider area include the Hagi onsen day-use comparison, Tawarayama Onsen’s Hakuen no Yu, the Yuda Onsen day-use guide and the Shimonoseki city onsen and sento guide.
