Okuhida Day-Use Onsen Guide: Four Baths, Four Different Setups
Choose an Okuhida day bath by showers, outdoor setting and season: Hirayu no Mori has washing facilities, while some open-air baths do not.
Checked: September 28, 2026
Okuhida’s public day-use baths are spread along the valley, so the cheapest ticket is not always the easiest visit. Hirayu no Mori has showers, indoor bathing and a rest area; the smaller outdoor baths are better if you are already clean and mainly want a soak. Shinhotaka no Yu adds a seasonal calendar, mixed bathing and river-level closures to the decision.
If you are coming from Takayama without a car, check the bus stop and return departure before choosing a bath. The Takayama-to-Okuhida access guide explains the route variants and stop names; a bus on the same valley line does not necessarily stop everywhere.
Quick comparison
| Bath | Current listing | Washing facilities | The catch |
|---|---|---|---|
| Hirayu no Mori | Adults ¥700, children ¥500; 10 a.m.–9 p.m., last entry 8:30 p.m. | Yes, with indoor baths, outdoor baths, sauna and a rest area | Check for dated maintenance closures; its private bath is a separate daytime product |
| Hirayu no Yu | Around ¥300 contribution; 6 a.m.–9 p.m., or 8 a.m.–9 p.m. in winter | No washing area | Irregular closing days; bring what you need and rinse before entering |
| Kojin no Yu | Around ¥300 contribution; 8 a.m.–10 p.m. | No washing area | Opens at noon on Mondays, Wednesdays and Fridays for cleaning |
| Shinhotaka no Yu | 2026 season: April 18–October 30, 8 a.m.–6 p.m.; around ¥300 cleaning contribution | Not a shower-and-change facility | Mixed bathing; swimwear or a bathing garment is required; river levels can close it |
The three low-cost outdoor baths are not substitutes for a full wash. If you have just finished a hike, need to wash your hair or want a reliable indoor option in bad weather, Hirayu no Mori is the straightforward choice.
Hirayu no Mori: the practical full-bath option
Hirayu no Mori is close to Hirayu Bus Terminal, making it an easy stop before a transfer or after a day outdoors. Its indoor and outdoor baths, washing stations, sauna and rest area make it a fuller facility than the outdoor-only options.
| Hirayu no Mori day use | Current details |
|---|---|
| Admission | ¥700 adults; ¥500 children |
| Hours | 10 a.m.–9 p.m.; last entry 8:30 p.m. |
| Hand towel | ¥200 |
| Private open-air bath | Two separate baths; ¥3,000 for 45 minutes, noon–3 p.m.; last reception 2:15 p.m. |
| Reservation | Phone reservations are not accepted; private-bath admission is separate from the regular bath |
The operator publishes unusually specific source-water details: a combined flow of 600 litres per minute, source temperature of 67.7°C and pH 6.7. It says the water is cooled with valley water, not reheated, recirculated or disinfected with chlorine. The source temperature is not the temperature of every bathing pool.
Hirayu no Yu: an outdoor soak beside the folk village
Hirayu no Yu sits beside Hirayu Folk Museum. The tourism association lists one outdoor bath each for men and women and describes the water as a simple hot spring. Admission is a contribution of about ¥300 rather than a fixed ticket. The listed hours are 6 a.m.–9 p.m. outside winter and 8 a.m.–9 p.m. in winter; closing days are irregular.
There is no washing area. Rinse before bathing, and use it as an outdoor soak rather than a place to shower after a hike. Its early opening is handy if you are already staying in Hirayu, but check locally if you are travelling there specifically for the bath.
Kojin no Yu: a riverside bath with a late close
Kojin no Yu is a simple, unstaffed open-air bath beside the Gamata River in Tochio. The association lists separate men’s and women’s baths, no washing area, and a contribution of around ¥300. Normal listed hours are 8 a.m.–10 p.m.; on Mondays, Wednesdays and Fridays it opens at noon because of cleaning.
That later closing time can suit an evening soak if your accommodation is in Tochio or Shin-Hirayu. It is less useful as an improvised stop if you have to catch a bus back to Takayama: check the return timetable first, and remember the bath has no showers or indoor fallback.
Shinhotaka no Yu: seasonal, mixed bathing and weather-sensitive
This riverside bath is open for the 2026 season from April 18 through October 30, 8 a.m.–6 p.m. The tourism association lists a cleaning contribution of around ¥300. The bathing pool is mixed, although the changing areas are separate; guests must wear swimwear or a bathing garment. The association says a bathing garment can be bought for ¥350 at Higaku no Yu or Nakazaki Sanso Okuhida no Yu.
Cleaning takes place on Mondays and Fridays. The Monday closure window is specifically listed as 1–3 p.m. High water can also force a temporary closure, so check the association’s latest notice before travelling up the valley for this bath. It is closed for winter after October 30 under the current schedule.
Getting between the baths without a car
Hirayu no Mori and Hirayu no Yu are the easiest pair to combine because both are near Hirayu’s main stop. Kojin no Yu is farther down-valley in Tochio; Shinhotaka no Yu is farther still, past the ropeway area. There is no short walk linking these locations. Check the Nohi Bus timetable both ways and do not count on catching the next service if a bath runs late.
Towels, showers and small costs to pack for
Hirayu no Mori has washing stations and sells towels, but the outdoor baths do not. For Hirayu no Yu and Kojin no Yu, bring your own towel and toiletries; each is a simple soak, not a full wash. Shinhotaka no Yu requires swimwear or a bathing garment, and the association lists a garment for ¥350 at nearby facilities. A low contribution does not include transport, towel rental or a meal.
Spring temperature and bathing feel
Hirayu no Mori lists source water at 67.7°C, pH 6.7 and a combined flow of 600 litres per minute. It says the water is cooled with valley water, not reheated or recirculated. These are source figures, not measurements of each pool.
The other three baths can be compared by setting, hours and access; their visitor pages do not give comparable water-temperature figures.
Pick a bath that fits the rest of the day
Choose Hirayu no Mori when you need a shower, a place to change or a dependable indoor bath. Hirayu no Yu is easiest to add while you are already in Hirayu. Kojin no Yu fits a Tochio stay or an evening when its cleaning schedule and your return transport line up. Shinhotaka no Yu is best treated as a seasonal stop with a clothing and weather check, not as a year-round fallback.
If your plan is centred on the ropeway, see the baths near Shinhotaka Ropeway. For overnight bathing setups in Shin-Hirayu, compare the Shin-Hirayu ryokan guide.
Questions people ask before choosing a bath
For a first visit, Hirayu no Mori is the easiest all-round option because it has showers, indoor baths and a rest area beside the bus terminal. The two simplest low-cost outdoor soaks are Hirayu no Yu and Kojin no Yu, each listed at about ¥300; neither has a washing area. Shinhotaka no Yu is mixed bathing, requires swimwear or a bathing garment and is seasonal. It is not a winter alternative if the current season has ended.
You can fit more than one bath into a day only if the buses, cleaning windows and opening hours line up. Do not treat the five villages as walkable from one another; check the current valley timetable before trying to combine Hirayu, Tochio and Shinhotaka.
Tattoo rules
The published day-use pages used for this comparison do not give a clear, shared tattoo policy for these four baths. Ask the individual facility before travelling if you need a definite answer; a small or unmanned outdoor bath may still have its own posted rules.
