宮の森 楽々温泉
A neighborhood hot-spring bathhouse with saunas and private baths
Closed the third Wednesday of each month; open through the New Year holidays. The main bath opens at 11:00, but the private family-bath rooms open later, from 14:00, and the food corner runs 11:30 to 23:00 (last order 20:30, with a weekday pause from 15:00 to 17:00). The outdoor tourmaline bath is closed from November to April, and the main rotenburo may also close temporarily on very cold days.
The main bath (1F) is 500 yen for adults, 150 yen for elementary schoolers and 80 yen for preschoolers; an 11-visit ticket book is 5,000 yen. The ten private family-bath rooms (2F) are priced separately: Course A is 1,500 yen for two adults (750 yen each for three or more), Course B is 1,700 yen for two adults (850 yen each for three or more), and either course is 1,000 yen for a single adult, 200 yen for an elementary schooler and 100 yen for a preschooler. Course B's sauna room is an extra 500 yen.

Miyanomori Rakuraku-Onsen is a neighborhood sento in central Muroran, run on real hot-spring water rather than a plain heated tub. The main bath downstairs pairs an indoor tub with an outdoor rotenburo (the water runs a little cloudy), a jet bath and a reclining bath, alongside a dry sauna and a mist sauna with a bubble-jet cold plunge. A tourmaline bath sits outside as a seasonal extra. Upstairs, ten private family-bath rooms, priced separately from the main bath, offer a soak away from the main hall. A food corner, a kids' space, a game corner and rest areas on both floors round out what is otherwise a straightforward local bathhouse.
