Kinugawa Onsen developed along both banks of the Kinugawa River in Nikko, Tochigi Prefecture, roughly two hours by train from Tokyo. Founded in the 17th century, its waters were originally reserved for high-ranking officials and Buddhist priests, only opening to the general public in the early Meiji period (from 1868). Different bathhouses across the resort draw on several spring types, including simple, chloride, bicarbonate, and sulfur springs, with the alkaline simple-spring water noted for being gentle on skin. The resort expanded heavily during the 1970s package-tourism boom, went through a period of visible decline after the 1990s economic downturn, and has since worked to revitalize itself.
The springs were first used in the 17th century by monks and were off-limits to ordinary people, becoming publicly accessible only after the Meiji Restoration in 1868. The resort grew rapidly during Japan's 1970s tourism boom before falling into decline in the 1990s, a period one urban planning professor cited in a 2005 ranking of Japan's 'ugliest' developed towns.
