Sakuragawa Onsen

Sakuragawa Onsen lies in a city named for the Sakura River that flows through its territory toward Lake Kasumigaura, the largest lake in Japan after Lake Biwa, whose shallow reed-fringed waters support one of the country's most important freshwater fisheries and a diverse wetland ecosystem that provides habitat for waterfowl and migratory birds across the Ibaraki lowlands. The city's proximity to Mount Tsukuba — the isolated twin-peaked volcano that rises dramatically from the Kanto Plain as Ibaraki's most iconic landmark — gives Sakuragawa a defining scenic presence that connects it to one of Japan's most beloved mountains, celebrated in Man'yoshu poetry as a place of pilgrimage and seasonal beauty. The onsen's mineral-rich geothermal waters, warmed by the same crustal heat that makes the Kanto Plain geologically productive, offer restorative bathing in a landscape defined by river, lake, and the distant silhouette of the sacred mountain.
