Hibikino’s Private Spa in Ikaho: What You Get and How to Reserve

Hibikino’s The Private Spa is a bookable group bath using Shirogane-no-Yu. It has an indoor bath and a reclining bath, and reservations are taken at the front desk on the day, in first-come order. It is not a private version of the inn’s Kogane-no-Yu outdoor bath: the two springs are separate experiences, with different water handling and access.

That distinction matters if you’re choosing Hibikino for a specific spring. The private session gives your group privacy with Shirogane. To try Kogane, use the shared outdoor bath; the inn identifies it as source-fed Kogane-no-Yu. For a fuller explanation of those springs, see the Ikaho Kogane vs Shirogane guide.

The Private Spa is one Shirogane session, not a choice of two springs

Hibikino announced The Private Spa in March 2026, saying it opened the previous month. The facility combines an indoor bath and a reclining bath, both described as Shirogane-no-Yu. The capacity is five people, and towels are included.

The published charge is per group size:

• One to three people: ¥5,500
• Four people: ¥6,600
• Five people: ¥7,700

Children count toward the group size. An infant can use the bath free if they do not need a towel, according to the inn’s notice. If your group includes a child, confirm how the inn will count everyone when you ask at the desk.

The booking rule is straightforward but leaves little room to plan ahead: request a session at the front desk on the day, and availability is first come, first served. The official notice does not publish a session length, operating hours, or an advance-reservation option. Ask about those points when you check in; don’t build your evening around a specific time until the desk confirms it.

Kogane and Shirogane are handled differently at the public baths

The shared outdoor bath uses Kogane-no-Yu, which Hibikino describes as continuously flowing from the source. Its indoor shared bath uses Shirogane-no-Yu and is listed as filtered and recirculated. The Private Spa also uses Shirogane, but the announcement does not specify its filtration or circulation setup, so the shared bath’s treatment description should not be transferred to the private facility without confirmation.

The private bath suits a group that wants a closed-door session with Shirogane, but one booking does not include both springs. To experience Kogane as well, use the shared baths, subject to the inn’s current opening schedule.

Both shared baths are listed from 3 p.m. to 1 a.m. and 5–9:30 a.m.; the sauna has shorter hours. Day-use hours depend on the plan, and admission may be unavailable when bookings are full.

Old pages may say there is no private bath

Hibikino ended its previous private-bath service in August 2024. That closure notice remains online, but it predates The Private Spa, announced in March 2026. The newer facility is real; the older notice explains why some search results still say that the ryokan has no bookable bath.

The new bath’s access rules are narrower than “private bath available” might suggest. The official announcement says to book at the front desk on the day, but it does not say whether non-staying visitors can reserve it. Day visitors are offered plans for the shared baths; if you are not staying overnight and want The Private Spa specifically, contact the inn before travelling rather than assuming it is included in a day-use ticket.

For day use, the current onsen page lists public-bath plans from ¥1,700 and a general window of 1–9 p.m. Actual hours vary by plan, and the inn asks visitors to call on the day because access can be restricted by its reservation situation. These terms refer to the shared baths; the page does not confirm private-spa access for day visitors.

If your priority is a private bath in the room throughout the stay, that is a different product from a timed private session. Hibikino lists specific guest rooms with their own baths, while its new spa is reserved at the desk as a separate paid option. Compare the exact room’s water source before paying a room upgrade. For another Ikaho property’s bookable private baths, see the Ikaho day-use private bath guide or Fukuichi’s two-spring bath guide; their source and booking terms differ.
