Tsurugi Onsen Fukui is a hot spring facility in Sabae, a city in Fukui Prefecture, Japan, internationally famous as the 'City of Eyeglasses' — producing approximately 90% of Japan's domestically manufactured eyeglass frames and exporting optical products worldwide, a remarkable industrial concentration that has made this small city the global capital of spectacle frame production. The naturally bicarbonate-rich spring waters here are valued for their gentle alkaline, skin-softening properties characteristic of the Fukui region's inland thermal zone, offering Sabae's precision craftspeople and optical industry workers a therapeutic bathing experience rooted in the earth's mineral richness. The charming juxtaposition of world-class optical precision manufacturing and the age-old Japanese tradition of therapeutic mineral hot spring bathing gives Tsurugi Onsen Fukui a uniquely distinctive character among Japan's thousands of onsen establishments.
