Echizen Onsen in the coastal city of Echizen, Fukui Prefecture, draws from springs beneath the Daicho coast, one of Japan's most celebrated locations for traditional Japanese paper-making, or washi, a craft that has been practised in the Imadate district for over fifteen hundred years and designated as a UNESCO Intangible Cultural Heritage of Humanity. The chloride-rich spring water provides warming, mineral-rich baths that have sustained the papermakers of this coastal community through the physical demands of their ancient craft, which involves standing for long hours in cold water pressing fibres into sheets. Visiting Echizen Onsen alongside the nearby Echizen Washi-no-Sato crafts museum creates a richly textured encounter with one of Japan's most venerable and beautiful artisanal traditions.
Insider tip — Echizen Onsen is located near the historic paper-making town of Echizen in northern Fukui, where artisans have crafted washi paper by hand for over 1,500 years. The alkaline bicarbonate spring at 40°C is said to complement the meticulous craft culture of the area, locals joking that the same waters that make paper smooth also soften human skin. Combine a soak with a visit to the Udatsu Paper Village artisan workshops for a full cultural immersion.
