Inawashiro Onsen Fukushima is located in Inawashiro Town, Fukushima Prefecture, on the shores of Lake Inawashiro — Japan's fourth largest lake and the 'Heaven's Mirror Lake' (Tenkyoko), whose exceptionally clear waters reflect the volcanic peaks of the Bandai mountain range and Azuma volcanoes in views of extraordinary scenic grandeur, and which serves as a staging area for hundreds of thousands of migratory whooper swans that winter on its shores in one of Japan's most spectacular wildlife spectacles. The chloride-rich thermal waters draw from the geothermal resources of the Bandai volcanic area, one of the most geologically active and scenically dramatic zones of the Tohoku highlands, providing warm mineral baths framed by views of the lake and volcanic peaks that define Fukushima's central highland landscape. Inawashiro is also the birthplace of Noguchi Hideyo — the bacteriologist who isolated the pathogen responsible for syphilis and contributed to research on yellow fever — whose childhood home near the lake is a Japanese pilgrimage site for scientists and educators, adding intellectual heritage to this scenic volcanic onsen destination.
