Bicarbonate
Classification

Sodium Bicarbonate spring

A sodium-led bicarbonate spring — the classic jūsō-sen style. Alkaline (pH 8.7), it gives the slippery, beauty-water feel on the skin and sits squarely in Japan's beauty-water family. At the wellhead the water is almost colorless and transparent, tasteless, with a faint hydrogen sulfide note.

271. あらたまの湯, Hamamatsu Super sento with onsen water for 730. Listed hours 09:00–21:00 (except Mon). They stamp the 60 Onsen of Shizuoka 24/25 booklet. They issue Toreco collector cards for the onsen. Based on the website, baths rotate M/F on different weeks. Online photos match. Has a shop, massage, restaurant, and chill zone. Popular spot — lots of elderly men in the morning. 1. Outdoor area. View of trees. Overall fairly comfortable and cozy, despite plenty of visitors in the onsen. 1.1. Large bath, clear water, "soft" water effect. Temperature 40. 1.2. Small bath, temperature 38. 1.3. Small bath, temperature 40. 1.4. Massage bath. 2. Indoor area. The interior actively uses the look of expensive exposed concrete. Comfortable to breathe. 2.1. Large bath, clear water, temperature 40. 2.2. Small bath, clear water, temperature 38. 2.3. Sauna. 2.4. Cold bath. Really enjoyed the onsen in the morning — recommended when visiting Hamamatsu.
