Oyado Tamaki: Choose a Room by Its Bath Water, Not Just the Tub

Oyado Tamaki has two public baths, two paid private baths and 12 guest rooms whose baths use hot-spring water. The room baths on that list use Shirogane-no-Yu; none is identified as a Kogane-no-Yu room. If private access to the brown Kogane spring is the priority, ask about the inn’s indoor rental bath, Koharu Biyori. A bath in the room name alone is not enough: the popular Hōrai room has a hinoki tub, but it is not one of the rooms listed as having hot-spring water.

The room decision comes down to how often you want to bathe

The inn’s FAQ identifies 12 rooms with Shirogane-no-Yu piped to the bath: ten rooms with an open-air bath and two Western-style rooms with indoor baths. That gives you privacy and the option to bathe without coordinating around the shared-bath hours. It does not add Kogane-no-Yu to the room.

The ten open-air-bath rooms are spread across three room groups: four upper-floor rooms, four rooms in the Itsukitei Annex, and two North Wing rooms. Names on the official room pages include Enju, Yuzuriha, Asunaro and Katsura among the top-floor options, plus Hanamizuki, Karin, Mokuren, Suiren, Tsuga and Sawara. The other two are Mayumi, a Western-style room with an indoor bath, and Zakuro, a Japanese-style room with a bath-and-living layout. Confirm the exact room name and bath type on the booking plan; room names and translated labels can differ across reservation sites.

The room categories differ in layout, not spring water. Enju is a large top-floor suite with a private open-air bath; Katsura has two Japanese-style rooms and sleeps up to eight. Itsukitei Annex rooms combine Japanese and Western furnishings, a deck and twin beds. Tsuga and Sawara are more compact Japanese-style rooms. Mayumi or Zakuro may suit guests who prefer an indoor bath; check the room plan for the exact setup.

Hōrai needs a separate check. It has a hinoki viewing bath, yet the inn’s FAQ says guest rooms outside the 12 named hot-spring rooms use Haruna mountain water. That makes Hōrai a room-with-a-bath option, not a confirmed Shirogane room. Standard rooms may have no bathtub at all, so do not interpret a private bathroom in a booking listing as an onsen feature.

How the two shared baths cover both Ikaho springs

Hashibami-no-Yu has baths for both Kogane-no-Yu and Shirogane-no-Yu. Tama-ibuki-no-Yu is centred on Shirogane, including its large bath and open-air bath. The two facilities exchange their men’s and women’s hours at 8 p.m.: from 11:30 a.m. to 8 p.m., women use Tama-ibuki-no-Yu and men use Hashibami-no-Yu; from 8 p.m. until 10 a.m. the next morning, the arrangement reverses.

That schedule matters if you want to see both bath layouts. A single visit before dinner gives each guest access to only one side; using the baths again after the exchange lets you try the other. A private Shirogane room does not replace the public Kogane bath if you want both sources during the stay. For the properties of the two springs themselves, see this Ikaho Kogane and Shirogane comparison.

Private baths: what the published price does—and does not—settle

Koharu Biyori is an indoor stone bath using 100% free-flowing Kogane-no-Yu. The inn lists it at ¥3,300 for 50 minutes. Akari is an outdoor private bath using recirculated Shirogane-no-Yu, costs ¥2,200 for 50 minutes and has a stated capacity of two to three people. These are meaningfully different choices: Koharu Biyori is the one with a published source-flow claim; Akari is the lower-priced open-air session.

The inn’s FAQ gives advance-booking times of noon, 1 p.m., 2 p.m., 6 p.m. and 7 p.m. for day-use private baths, with separate admission charges. Those times and fees are for day visitors; the inn does not publish the overnight reservation process or charge here. Ask when booking whether a private session can be added and how to reserve it. The Ikaho day-use private-bath guide covers walk-in visits.

Tattoo policy and the practical choice

The inn does not allow guests with tattoos to use the shared baths. Its stated alternatives are a guest room with a private open-air bath or a paid private bath. A small tattoo that can be completely covered with a seal is permitted in the shared baths; the front desk can provide one. If this affects your booking, confirm the exact room or private-bath arrangement with the inn rather than assuming that every room with a bathtub qualifies.

Choose a standard room if you are comfortable with shared bathing and want access to both springs through the two public baths. Pick one of the 12 confirmed Shirogane rooms if you expect to bathe privately more than once or need to avoid shared bathing. Add Koharu Biyori only after the inn confirms an overnight reservation and its terms; it is the clearest listed route to a private Kogane soak. For a broader Ikaho stay decision, the accommodation-area guide covers the walk from the stone steps and the different hillside locations.
