The bath
What you’ll find
An aging but well-regarded roadside super-sento near Takasaki IC where every bath, indoor and outdoor, runs on unheated 46-55C iron-tinted sodium chloride kakenagashi spring water, with an outdoor sauna and a large deep cold plunge, though recent reviews report declining maintenance, a roach sighting, and one report that tattoos (even taped over) get you ejected.
