Is Kurotake Worth Booking for a Private Onsen in Hirugami?
Nine of Kurotake’s 16 rooms have private open-air springs; standard rooms have unit baths, and the inn does not take day bathers.
Kurotake makes the most sense when you expect to spend real time at the inn. A private bath is useful before dinner or again the next morning; if you arrive late and leave soon after breakfast, the upgrade may sit unused. The official room list says nine of its 16 rooms have an open-air bath, so “Kurotake room” alone is not enough when comparing plans.
Which room categories have a hot-spring bath?
The three room wings with private outdoor baths are I, Ro and Ha. The fourth wing, Ni, has standard Japanese-style rooms and a unit bathroom that the inn says is not fed by the hot spring.
| Wing and room type | What the official listing says | Capacity |
|---|---|---|
| I Wing detached special room | Garden and square stone open-air bath; Japanese-style room with a separate bedroom | 3 |
| I Wing Japanese–Western room | Garden and square stone open-air bath | 3 |
| Ro Wing special Japanese room | Square stone open-air bath | 3 |
| Ro Wing Japanese–Western or Japanese room | Round ceramic bath | 3 |
| Ha Wing Japanese–Western room | Private open-air bath; room looks onto the changing seasons | 3 |
| Ni Wing standard room | Japanese-style room; indoor unit bath, not hot-spring water | 3 |
The two special rooms with beds were announced in January 2026; the inn names I Wing room 4 and Ro Wing room 3. If sleeping on a bed is important, confirm that exact room assignment when booking rather than assuming every Japanese–Western room has one. Room photos also do not establish which way a bath faces or how private its outdoor space feels, so check the floor plan and room description for your selected date.
A private bath is not the only bath here
Kurotake also has gender-separated public indoor and open-air baths. The published bathing window is 3 p.m. to midnight, then 6–10 a.m. the next day. There is no time-based change between the men’s and women’s baths listed on the inn’s hot-spring page. If you book a private-bath room, it adds flexible access in your own room; it does not mean the public baths are unnecessary.
The inn identifies the water as a simple sulfur spring, classed as low in dissolved solids, alkaline and high-temperature at the source. Hirugami’s tourism association publishes area-level figures of pH 9.7 and a source temperature of 47.4°C. Neither figure is a measured temperature for your room bath. Kurotake does not publish a fixed temperature for each private tub, so ask the inn if that detail affects your choice.
Kurotake does not accept day visitors for bathing. Its FAQ also says a separate chartered open-air bath is not currently available. If your plan is simply to try Hirugami’s water for an hour, a day-use facility is the better fit; the Hirugami night-tour itinerary covers the area’s public bathing options and event-night timing.
Make the room upgrade earn its place
I would compare the room supplement against the hours you will actually be at the property, not the number of baths in the brochure. An overnight plan with an afternoon arrival, a bath before dinner and another before checkout gives the private tub two clear uses. A late arrival after an evening activity leaves much less time, especially because the public bath closes at midnight and reopens at 6 a.m.
The private bath, courtyard and dinner are the main reasons to spend time at Kurotake. If you plan several stops across the valley, you may not use the room enough to justify paying extra for its bath.
The lobby night bar is open after dinner until 10 p.m. Dinner has set seating times, so tell the inn at booking if you are joining a night-sky event. There is no transfer to the ropeway venue; use a car or taxi.
Room prices vary by date, room and meal plan. Compare the same dates and party size, then check whether dinner and breakfast are included. Achi Village’s lodging tax began on June 1, 2026: the inn lists ¥300 per person per night when the taxable lodging charge meets the town’s threshold. It also lists a separate ¥150 bathing tax for guests aged 12 and over. Confirm the final amount with the booking plan.
Getting there is the main planning constraint
Kurotake is about a five-minute walk from the Hirugami Onsen bus stop, according to the inn. It can arrange a free pickup from the Hirugami Onsen Guide Center or Achi parking area, but you must reserve by the day before. The inn does not offer pickup from a railway station. Its page lists 13 free parking spaces; in winter it advises winter tires and warns that ice or snow can make the roads slippery.
If you are arriving by highway bus, settle the last leg with the inn before departure. For the return, confirm a stop and departure time that work with checkout; do not assume a station shuttle. Travelers who want to combine Kurotake with the night tour should also arrange the ride to and from Heaven Sonohara in advance.
For a room-by-room comparison with another Hirugami inn, see the Oyado Sansui stay guide. Sansui also has specific private-bath room categories, but its public-bath schedule and reservable private baths follow different rules.
