Classification

Sodium Bicarbonate spring

A sodium-led bicarbonate spring — the classic 'jūsō-sen' (soda-water) style. Weakly alkaline and soft on the skin, it sits in the Japanese beauty-water family. Moderately mineralized at 3.5 g/kg dissolved solids, the wellhead emerges at 37 °C — right at the threshold of a true hot spring, which makes for a comfortable long soak.

449. Hasami Onsen Yujiro, Nagasaki Onsen for 800. Operating hours listed as 10:00 to 22:00. They stamp the 88 Onsen of Kyushu book. Bath photos from the internet, partially accurate — in the outdoor area the lower fence opening was closed, and the park across the street had cherry blossoms in bloom. Outdoor bath in stone. Through openings you can see a cherry blossom alley (caught it at peak bloom), but the view is only visible when standing — sitting in the bath, the fence blocks the view. Clear water with a slippery feel, slightly carbonated. Temperature around 40-41. Indoor area. Comfortable to breathe inside. 1. Bath with clear water, some sparse fine brown mineral deposits. Temperature 40-41. 2. Bath with clear carbonated water, temperature around 37. 3. Sauna. 4. Cold bath. Pleasant place, but due to its remote location, only worth making a special trip for the cherry blossoms. 31.03.2025
