One Night in Yamashiro Onsen: A Relaxed Soyu and Kosoyu Itinerary

Yamashiro Onsen’s two public baths are only a short walk apart, but they are not interchangeable. Soyu has washing stations; Kosoyu recreates the bathing style of an earlier public bath and has no showers, taps, soap or shampoo. On a one-night stay, visit Soyu first, wander the old bathhouse quarter, then decide whether you want a second soak at Kosoyu that afternoon or the next morning.

Day one: arrive, walk the quarter and bathe before dinner

Get to the inn before carrying your bags around

From Kaga Onsen Station, the Hokutetsu Kaga Bus Onsen-Yamanaka Line takes about 15 minutes to the Yamashiro Onsen stop. Yamashiro Onsen East Exit and the other stops in the district are separate; check which one is closest to your inn before boarding, particularly if you have luggage. Some inns offer a station shuttle, but the pickup point and departure times are property-specific. Confirm them directly rather than treating a shuttle as an extension of the public bus.

Leave your bags at the inn or ask whether you can drop them before check-in. The walk between the public baths is short, and it is much easier to explore the stone lanes without luggage. The bus timetable was revised on March 15, 2026; check the operator’s current schedule against your arrival train and your return connection.

Early afternoon: Iroha Soan, if the timing works

If you arrive with time to spare and it is not Wednesday, visit Iroha Soan, the house where the artist and ceramicist Kitaoji Rosanjin stayed in 1915–16. The rooms include his former workspace and study; a storehouse gallery displays works. It is open from 9 a.m. to 5 p.m., with last entry at 4:30 p.m. Admission is ¥560 for adults; high-school students and younger visitors enter free. The museum is closed on Wednesdays, though it opens when Wednesday is a public holiday. Ask about year-end and New Year hours.

The house sits in the same compact district as the baths, so there is no need to turn the afternoon into a driving itinerary. If your train arrives late, skip the museum rather than trying to squeeze it in before the doors close. Have lunch before the bath sequence; this plan does not depend on any one restaurant’s opening hours.

Around 4 p.m.: wash at Soyu, then try Kosoyu

Start at Soyu, the modern public bath. It is open daily from 6 a.m. to 10 p.m. Its changing rooms have washing stations, but toiletries are not supplied; bring your own or buy them at the bathhouse. The association describes Soyu as a 100% source-water bath with no added water, using a heat-exchange system.

Then walk a few minutes to Kosoyu, a reconstruction of the Meiji-era public bath. Its tiled walls feature Kutani ware, and there is a small second-floor rest area.

The combined ticket saves money only if you visit both; buying the two admissions separately costs ¥1,200.

Kosoyu is built around soaking rather than a modern wash. There are no taps or showers, and soap and shampoo are not allowed. Rinse at Soyu first, then go to Kosoyu with the expectation of a short, quiet soak. The fourth Wednesday of every month, both baths pause from 6 a.m. until noon and reopen after midday, so do not schedule a morning visit then.

Winter hours differ at Kosoyu: from December through February, it opens at 7 a.m. and closes at 9 p.m. Soyu keeps its 6 a.m.–10 p.m. hours. If you are buying a combined ticket, check that both places will be open for the time you have.

Dinner and where to stay

The historic bathhouses are close enough to walk back from, but dinner is usually the part that needs coordination. If your room includes a meal, match your arrival and bathing time to the inn’s dinner seating. For dinner out, check what is open on your date before deciding to skip the meal plan; the public-bath district is compact, but restaurant hours are not all the same.

Choose an inn for the kind of evening you want. Araya Totoan is beside the old bathhouse quarter, and only selected room categories have a private open-air bath drawing on the hot spring. Hatori has a station shuttle and reservable private baths; ask which pickup and bath times are available for your stay. Rurikoh has five private open-air baths, but its current notice says three remain unavailable for maintenance. Check the operating status before booking if a private bath is central to your choice.

Check dates and room types at Araya Totoan, Hatori, or Rurikoh. Room facilities and shuttle arrangements vary; confirm the details for your dates with the inn.

Day two: one early bath, then back to the station

Choose one public bath before breakfast or checkout. Soyu opens at 6 a.m. all year. Kosoyu opens at 6 a.m. outside winter and at 7 a.m. from December through February. If the fourth Wednesday of the month falls on your stay, neither opens until noon, so use your inn’s bath instead or save the public soak for the previous afternoon.

After checkout, ask the inn whether it can hold your luggage until the bus. The ride back to Kaga Onsen Station takes roughly 15 minutes, but service is not a turn-up-and-go urban route. Check the return departure before deciding how long to linger over breakfast or take one more walk through town. If you are connecting to a train, leave a buffer for the wait as well as the ride.

If you are continuing to another Kaga hot-spring district on day two, check the onward bus before adding a second town. Our no-car Yamashiro–Yamanaka day-trip plan maps that connection; the Kaga district comparison helps decide whether the extra transfer fits your stay.
