¥450 in a Taisho-romance building: the thick, silky beauty bath
Ureshino Onsen sits in the tea country of south-western Saga, and its thick, clinging bicarbonate water ranks among “Japan’s three great beauty baths”. Siebold’s Bath is the municipal bathhouse in the middle of town on the Ureshino river: a domain bath in the Edo period, visited in 1826 by the German physician Siebold, rebuilt in the Taisho era to a German design as the Western-style “Koyu Onsen” that became the town’s landmark. Demolished when it decayed, it was reborn in 2010 at residents’ request with the old look recreated — today’s orange-roofed building. The main bath downstairs costs ¥450; upstairs are five private baths, including a wheelchair-accessible room, and a tatami lounge. With ryokan day bathing at ¥1,100–1,500 here, this is the easiest way to try the beauty water.
Tips & cautions
- Cash only. Closed 3rd Wednesday. Opens at 6 a.m. — good before breakfast.
- Private baths are first-come (no booking); weekend afternoons mean waiting — go on weekdays or mornings.
- The silky water makes floors slippery; soak in 15-minute spells to avoid dizziness.
- Food delivery can be ordered to the upstairs lounge — many order Ureshino’s famous onsen yudofu.
- The free-entry day on 1 April is extremely crowded.
- The free Siebold foot bath (1 min), yudofu restaurants and tea cafés cluster in the town.
