Classification

Sodium-Calcium Chloride-Sulfate spring

A sodium- and calcium-led chloride-sulfate spring rising hot at 56.5 °C from the wellhead, with sulfate adding quiet body to a salt-led mineralization. Alkaline pH 9.0 gives the slippery, beauty-water feel on the skin, while the moderate dissolved load (about 2.6 g/kg) lands well above a plain simple-thermal source — there is enough chloride and sulfate to leave a faint mineral film without crossing into a heavy salt coating.

257. Yu~topia Kannami Super sento with onsen water for 700. Listed hours 10:00–21:00 (except Tue). They stamp the 60 Onsen of Shizuoka 24/25 booklet. Based on Google photos (attached to the review), Mt. Fuji should be visible from the outdoor bath (I went late in the evening without a Fuji view), though it seems visible only from certain spots and probably not spectacular. Has a restaurant, chill zone, shop, massage, massage chairs, and a private bath for 1000 (didn't take it). 1. Outdoor area. 1.1. Large outdoor stone bath, clear water, temperature 40. 1.2. Small stone bath with 2 utaseyu. 2. Indoor area. Strong chlorine smell inside, stuffy. 2.1. Main indoor bath with clear water, temperature 42. Water smells of chlorine. 2.2. Main indoor bath with bubbles, very strong chlorine smell, uncomfortable to sit in. Temperature 39–40. 2.3. Small indoor bath for two with jets, temperature 39–40. 2.4. Two saunas. 2.5. Cold bath. The indoor area is essentially a fail due to chlorine, and the Fuji view, if any, is questionable. I'd say this is a skip.
