Classification

Sodium Chloride spring

A sodium bicarbonate-chloride spring that emerges at a scalding 92.5 °C — among Japan's hottest natural sources. Weakly alkaline at pH 8.17, the bicarbonate-led chemistry gives the slippery, skin-smoothing feel that puts Ureshino in Japan's beauty-water family, with a chloride sub-type adding heat-retaining body. Sodium-dominant and softly mineralized, it carries Ureshino's signature soft-on-the-skin character.

441. Ryokan Oomuraya, Ureshino Visited for higaeri for 6 Ureshino tickets. Higaeri listed from 15:00 to 22:00. They stamp the Ureshino 10 Onsen book. The changing room and onsen interior are done in a quite stylish and pleasant way. There's special background music playing (decent overall, not distracting) — they even credited the artist separately. Bath photos from the internet are roughly accurate — I visited in the evening. Indoor bath with clear water that has a soapy feel. Temperature 41-42. View through glass of the buildings across and a bit of the bridge from one angle. Air inside is okay. Outdoor bath with clear water that has a soapy feel. Temperature 41. View of fairly plain buildings across the way. A pleasant place, worth visiting for higaeri when in Ureshino. 03/30/2025
