Miyano Onsen: Day-Use Prices, Opening Hours and the Private Bath
Planning a Miyano Onsen day trip in Koka, Shiga? Compare public-bath and private-bath prices, check day-use hours, and see what to confirm before driving out.
Miyano Onsen is a small hot-spring inn in Koka, Shiga, with a public day-use bath and a separately booked private outdoor bath. The newest notice updates the private-bath rates, while the inn’s spa page still shows older prices; the current figures and source dates are separated below.
The spring data is unusually specific: the source temperature is 14°C and the pH is 7.7. That 14°C figure describes the spring at its source, not the temperature of the bath. Miyano is a quiet inn rather than a large bathing complex, and a car makes the visit much simpler. Check the inn’s notices before setting out; day-use closures can be announced for particular dates.
Public-bath admission and towel hire
| Day-use option | Price | Hours and details |
|---|---|---|
| Adult public bath | ¥1,000 (about HK$50 / NT$202) | — |
| Elementary-school child | ¥800 (about HK$40 / NT$162) | Public bath |
| Younger child | ¥500 (about HK$25 / NT$101) | Public bath |
| Towel rental | ¥100 (about HK$5 / NT$20) | Face towel |
| Bath towel rental | ¥200 (about HK$10 / NT$40) | Separate charge |
Public-bath admission is available to day visitors from 11:00 am to 8:00 pm. These rates and hours are listed on the inn’s spa page. Currency conversions are approximate; the yen price is the operator’s listed rate.
Private outdoor bath: one-hour group rates
| Booking | Price | Session |
|---|---|---|
| Two people | ¥5,000 (about HK$248 / NT$1,010) | One hour |
| Family of up to four | ¥5,500 (about HK$273 / NT$1,111) | One hour |
The private-bath price comes from the inn’s April 21, 2026 notice, which says the new rates began in May. Its spa page has not caught up and still shows ¥4,500 and ¥5,000. Use the newer notice when budgeting, then confirm the rate and availability with the inn when arranging your visit.
The private bath is a separate one-hour session, not an upgrade included with the public-bath ticket. The official pages do not spell out the day-visitor reservation process, so contact the inn to check availability and arrange a slot. No solo rate is listed; ask before assuming the group rate can be split or reduced. Towel rentals are also separate from public-bath admission.
Public bath or private outdoor bath?
The public bath is the straightforward choice if you want a short soak and are comfortable using a shared bath. The inn describes a wooden bathing tub and a foot-rock-bed area; this is a smaller ryokan setting, not a destination spa with a long list of saunas, relaxation rooms and other facilities.
Kakuremino, the private outdoor bath, uses a Shigaraki ceramic tub and is reserved for one group for an hour. That can suit a couple who want to bathe together or parents who need to manage a child’s pace.
The spa page does not fully explain current availability or arrangements for day visitors, so contact the inn before building a tight itinerary around it. A private bath is not confirmation that tattoos are accepted; the public pages give no clear current tattoo policy.
The inn’s room with a private open-air bath is another separate offering: it is a guest-room feature, not the same as the public day-use family bath. The official spa page identifies the room as Zenjubo. If you are comparing an overnight stay with a day visit, check the room details and your chosen plan directly with the inn.
Opening days: check the notice before driving
Day-use bathing is listed as 11:00 am–8:00 pm. That is the public day-visitor window; the separate bathing schedule shown elsewhere on the spa page includes early-morning and evening sessions for the inn’s facilities and should not be assumed to extend day-use access.
Miyano’s current spa page gives no fixed weekly closure schedule. The inn has posted date-specific closures, including for maintenance, and its news page has no full monthly calendar. Check the latest notices or call before making a dedicated drive, especially on a holiday. The town’s Koka tourism listing is useful for background, but its private-bath price is older than the inn’s 2026 notice.
Getting there without a car takes planning
Miyano Onsen is at 364 Sugitani, Kōnan-chō, Koka. The inn has 40 free parking spaces, available first come, first served, and its access page points visitors to the Kōnan Interchange. This is the easiest way to fit a soak around other stops in Koka or Shigaraki.
There is a pick-up service from JR Kōnan Station, but the inn explicitly describes it for overnight guests who contact it in advance. Day visitors should not assume they can use the shuttle. If travelling by train, ask before booking the private bath or a meal plan; otherwise, allow for a taxi on the final leg. The inn’s access information has the current directions and contact details.
For a broader comparison with larger facilities, see the Koka and Konan day-use onsen guide. If a private bathing space is the main requirement, the Shiga private and family bath comparison covers other options. Tattoo rules vary by facility, so check the Shiga tattoo-friendly onsen guide rather than inferring permission from the presence of a private bath.
Is Miyano Onsen a good fit?
It makes the most sense as a quiet stop on a Koka-area drive, especially for a pair or family who specifically wants an hour in a private outdoor bath. The public bath is a more modest spend if all you need is a soak, but the inn’s rural setting makes it a poor choice for an improvised stop without checking transport and closure details first. For a larger day-spa setup, compare it with Kusatsu Yumoto Suisyun or other facilities in the Shiga day-use onsen guide.
