Shima Seiryu-no-yu Public Bath
¥600 · Day visitors: Yes · Outdoor bath: Yes
A clean, well-run town-operated day-use bathhouse in Shima Onsen with a naturally hot, unheated kakenagashi spring, a riverside outdoor bath, full amenities, and a 2-hour ticket system, though operating hours have recently been shortened and can vary.
Sawatari Onsen Public Bath
¥300 · Outdoor bath: No
A beloved, old-style two-tub communal bath known as 'Kusatsu's finishing bath,' with scalding source-fed sulfur water full of yunohana flakes but no shower stations and no soap provided.
Gomuso-no-yu Public Bath
Free · Day visitors: Limited hours
A free, unattended stone-tub communal bath at the source of Shima Onsen, open to visitors 9:00-15:00 with kakenagashi water running very hot, no soap allowed, and no lockable storage.
Kawara-no-yu Public Bath
Free · Day visitors: Yes · Outdoor bath: No
A tiny, free riverside community bathhouse in Shima Onsen with a hot, naturally-flowing sodium-calcium chloride-sulfate spring, open 9:00-15:00, but with real privacy and safety caveats: no toilet, no door lock, and repeated reports of tourists peeking in while bathers undress.
Kami-no-yu Public Bath
Free
A free, donation-based community bath in Shima Onsen with two kakenagashi tubs of differing heat (one often scalding, one milder), no washing facilities or amenities, no parking, and posted rules against mixed bathing and soap use.
Kuni Akaiwa Onsen Choei-no-Kakureyu Day-use Onsen
¥100 · Day visitors: No · Outdoor bath: No
A tiny unmanned community bath (100 yen honor-box) in a hidden hillside hamlet with mild alkaline source-fed water, but the source has repeatedly dried up over the years and the most recent 2024 reviews report it permanently closed.
Shiriyaki Onsen Benten-no-Yu
¥500 · Day visitors: Yes · Outdoor bath: No
A small, newly built (2023) communal indoor bathhouse fed by the Shiriyaki hot spring, with hot kakenagashi water but no outdoor bath, sauna, or amenities.
Shiriyaki Onsen Bade Kuni
¥400 · Day visitors: No · Outdoor bath: No
A modest medical-center-annex day bath on the Shiriyaki hot spring source with a single small kakenagashi indoor tub and an onsen pool, but recent reviews report conflicting temporary and permanent closure as of late 2023 with a new building under construction.
Genroku-no-Yu
¥1,500 · Day visitors: Yes · Outdoor bath: No
A historic Showa-era day-use bath at the Sekizenkan ryokan in Shima Onsen, with five open tubs of varying temperature in one ornate room, a steam sauna, and drinkable onsen water, though several reviewers question whether the water is truly source-fed.
Mori-no-Yu
Outdoor bath: Yes
A guests-only indoor-plus-outdoor bath at the historic Sekizenkan ryokan in Shima Onsen, with plentiful showers, a very hot source-fed outdoor tub amid autumn foliage, and a Yogibo lounge area.
