Makinohara Onsen stands on the edge of the Makinohara Plateau, Japan's largest tea-growing tableland, where vast fields of Camellia sinensis stretch across a broad upland terrace with the Pacific Ocean shimmering on the southern horizon in views of extraordinary breadth and beauty. Tea cultivation was introduced to Makinohara by former samurai seeking livelihoods after the Meiji abolition of the feudal system, and the plateau's tea has since become one of Shizuoka's most prized agricultural products, synonymous with quality Japanese sencha. The onsen's geothermal mineral waters invite guests to soak while overlooking a landscape that transformed a samurai legacy into one of Japan's most iconic agricultural panoramas.
Insider tip — Makinohara plateau rises above Shizuoka's coast as Japan's largest tea-producing plateau, its rolling hills striped with tea rows and with views of Suruga Bay. Onsen facilities here draw alkaline bicarbonate water that leaves skin noticeably smooth — locally called bijin-no-yu or beauty water. The ideal visit pairs a morning stroll through tea plantations with an afternoon soak and fresh-brewed sencha from the surrounding estates.
