Onsen and baths in Maebashi

A large urban day-spa with a genuine but partly recirculated hot-spring source, multiple sauna types, rock-bath spa (ganbanyoku), restaurant, and long hours, popular enough that crowding and manners are recurring complaints.

A very cheap roadside-station day bath on Mt. Akagi's slopes overlooking Maebashi's night view, with one indoor and one outdoor bath, sauna, and restaurant; several reviewers note pushy elderly regulars and a coin-only shoe locker despite cashless payment, and one reviewer reports the official no-tattoo rule is not actually enforced.

A large, modern roadside-station super sento with an attached pool, salty sodium-chloride baths, sauna, outdoor bath, restaurant, and private bathing rooms, popular with families and hikers off Mt. Akagi.

A polished station-front super-sento built around a genuinely source-fed sodium-chloride hot spring, with indoor and outdoor baths, dual saunas, cold bath and a well-liked restaurant, though it gets very crowded and free hair dryers routinely run out; one reviewer reports a month-long renovation closure starting August 17.

A large natural-hot-spring super sento in Maebashi with indoor and source-fed outdoor baths, carbonated-spring tubs, sauna and a cramped cold plunge, a restaurant with mixed reviews, and a well-documented, recurring problem with rude long-time regulars monopolizing space and harassing other bathers.

A sento-style bathhouse and sauna complex at the Maebashi Akagi roadside station, using heated tap water with bath salts rather than a real hot spring, offering sauna, cold plunge, carbonated and outdoor baths.

A cheap, no-frills neighborhood health-land bathhouse in Maebashi with two heated/recirculated springs, indoor and outdoor tubs, a sauna, a tiny single-person cold plunge, and an on-site (mixed-review) restaurant, popular with local elderly regulars.

A clinic-affiliated therapeutic onsen in Maebashi with an indoor walking pool popular for rehab, oil-scented spring water, sauna, and an official (unevenly enforced) tattoo ban.

A tiny, wood-fired Showa-era neighborhood sento in Maebashi with a very hot regular bath and jacuzzi, no shower, no sauna, and bring-your-own soap and shampoo -- one reviewer notes tattooed and yakuza-adjacent customers are tolerated, though that is a single unconfirmed report.

A nostalgic Showa-era neighborhood sento in Maebashi with a medicinal herbal bath (yakuyu), one of only two sento left in the city; open just three days a week, and its showers have reportedly been broken for years, so bathers wash from a basin instead.
