Kikugawa Onsen serves a city nestled in the rolling tea country between Shizuoka and Hamamatsu, where some of Japan's finest green tea is cultivated on sun-warmed hillsides that produce the delicate sencha and fukamushi varieties prized by connoisseurs across the country. The Kikugawa River runs through the city's center, its waters draining from the forested highlands of the Haibara district before reaching the Pacific coast near Yaizu, threading together a landscape of rice paddies, tea gardens, and traditional farmhouses. The onsen's mineral waters draw warmth from the geothermal activity that underlies this productive agricultural region, offering a restorative pause amid Shizuoka's verdant, tea-scented countryside.
