Yunoshimakan in Gero: Choose the Building Before the Room

Yunoshimakan is a hillside inn built around its architecture as much as its hot spring. The registered main-building rooms preserve the original layout, but they do not have a private bathroom. Guests who want Gero water in their room should look at Keizansō, the annex outdoor-bath rooms or a named special room instead of booking the least expensive main-building plan by default.

The room category determines the bathing setup

The main building's entrance, connecting corridor and three-storey wooden lodging building were registered as Tangible Cultural Properties in 2010. Its standard rooms have a washbasin and toilet but no tub or shower. That is part of the historic-room arrangement, not a missing amenity to discover after arrival. If private bathing matters, book a room category whose description specifically mentions the bath.

Two room updates to know about in 2026

The Keizansō wing is high on the hillside, and the inn says spring water is pumped to its top floor. Each room has a view bath with a window that opens fully for a semi-outdoor feel.

Suisen-no-ma is not being sold from September 2026 through January 2027 while the inn prepares renovation work planned from November. Older room pages may still show it, but the restart date has not been announced. The inn has also listed closures for November 25–26, 2026; check its official notice before planning a stay on either date.

The annex has six rooms listed with source-fed indoor and outdoor baths. However, their layouts are not identical. Sumire-no-ma reopened after renovation in May 2026 with a shower room and dedicated outdoor bath, but no indoor tub. Some annex and special rooms also require stairs to reach. If you need lift access or a step-free route, confirm the exact room and route with the inn before paying.

Public baths and four free family baths

The shared baths are open from 3pm to 1am, then 5am to 10am. They close for cleaning and a gender changeover between 1 and 5am, so they are not available all night. The inn lists alkaline simple spring water at pH 8.90, a source temperature of 55°C and a use-point temperature of 42°C. Those temperatures refer to different points in the system. The shared baths use both partial recirculation and flow-through supply.

There are four free family baths—Ginrei-sen, Furo-sen, Shippō-sen and Tamanoi-sen—in the basement of the Western-style entertainment building. Reserve at the front desk after arrival. They can be a useful alternative to upgrading to a private-bath room if you only want one private session, but reaching them involves stairs. Confirm whether the room-side or family-bath arrangements are suitable if anyone in your party has mobility needs or tattoos; do not assume a private bath automatically overrides the inn's bathing rules.

Use the station shuttle; the inn is uphill

Yunoshimakan is on the hillside above town. Its free station shuttle leaves Gero Station at 1:35, 2:35, 3:35, 4:35 and 5:25pm, and leaves the inn for the station at 8:30, 9:00, 9:30, 10:00, 10:30 and 11:10am. Plan your train around those runs instead of hauling luggage uphill. The inn also lists free parking.

The property has several linked buildings and older corridors. Allow a little time after arrival to find the correct room and bath. The stone and timber character is part of the stay, but if a modern hotel layout or quiet room is more important than the architecture, consider that before booking.

The inn's published rule generally bars tattoos from the public baths; do not assume the four family baths create an exception. Ask the inn about your situation and the exact bath before booking. The family baths are free but sit downstairs in the Western-style entertainment building, so they are not a step-free option.

For a family, the private baths can be useful, but children's meal and bedding costs add to the adult rate. The inn's current policy lists a child dinner plan at 70% of the adult rate; a toddler meal plan with bedding is listed at ¥14,300.

Local taxes are separate: Gero City's bathing tax is ¥150 per adult per night, and accommodation tax is ¥100 or ¥200 per person depending on the lodging-only amount, with exemptions. Check the booking breakdown and the inn's current child plan before comparing totals.
