Uses natural hot spring water
258. Yugo-mishima Hot Spring, Mishima Super sento with onsen water for 790–890. Listed hours 06:00–24:00. They stamp the 60 Onsen of Shizuoka 24/25 booklet. Based on online photos (attached to the review) and the actual location, Mt. Fuji should be visible from the men's outdoor bath (I went late in the evening without a view). There's a rooftop observation deck with a foot bath and Fuji view, a restaurant, a very nice chill zone, a shop, a hyperbaric chamber, massage chairs, and a private bath (didn't take it). Online photos match, excluding Fuji. Clear water. Indoor bath temperature 42, outdoor 40. There's a sauna. While the baths aren't the strongest point here, everything else makes it a good place — excellent operating hours, Fuji view, rooftop observation deck, and a really great chill zone.
