Sakunami Onsen is located 25 km northwest of Sendai in the Nishikawa valley, where calcium-rich geothermal waters from the Zao volcanic system have attracted bathers from Tohoku's largest city since the Edo period, creating a classic Japanese mountain onsen escape within easy reach of a major metropolis. The forested valley offers year-round thermal bathing — dramatically beautiful in winter when snow-laden cedar trees frame the open-air rotenburo baths — with access to the Otafuku waterfall hiking trail and autumn foliage of the Nishikawa gorge. Sendai's rich Dateculture — the legacy of the powerful samurai lord Date Masamune, the 'One-Eyed Dragon of Ōshu' — surrounds this onsen with one of Tohoku's most compelling feudal historical contexts.
