Kusatsu · As of late 2025/2026, day visitors appear allowed roughly 09:00-16:00, with the bath locked to residents-only overnight (about 16:00-09:00); this is a change from 2021-2024, when many reviews reported it was residents-only with no visitor access at all, so status should be reconfirmed on arrival.

Katashina · Day-use bathing is offered for 1000 yen, but only within a narrow window (around 14:00-20:00 per one visit); another visitor reports being turned away every time with a posted 'no day-use bathing' sign, so hours may be inconsistently enforced or seasonal.

Ota · A regular public sento open to anyone, but evening-only (around 17:30-18:00 opening) with historically inconsistent hours; the most recent visit (April 2026) found a temporary-closure notice posted, so current operating status is uncertain.

Minakami · Signage at the door says residents-only, but five reviewers describe paying 300-400 yen and being let in without trouble by whoever is present.

Naganohara · The resort bathhouse is open to day visitors, not just hotel/golf guests.

Kusatsu · Five 2025-2026 reviewers describe this bath as reopened to tourists during the day, with locals-only hours roughly 16:00-22:00; one 2025-12 reviewer says the tourist information office told them it is locals-only at all hours, so confirm locally before visiting.

Minakami · Unmanned self-pay communal bath, easy to walk past since it looks like a community hall with no signs of being open.
