Haibara Onsen

Haibara Onsen in Makinohara city, Shizuoka Prefecture, lies on the eastern edge of the Makinohara Plateau, Japan's largest tea-growing region, where vast fields of carefully trimmed Camellia sinensis stretch across the gently rolling upland between the Oi River and the Suruga Bay coastline, producing some of Japan's finest green teas in a landscape as distinctive as the thermal springs it contains. The siliceous spring water provides smooth, revitalising baths that draw tea farmers, cyclists, and travellers exploring the ancient Tokaido highway between Tokyo and Kyoto through this historically important transit region. The combination of therapeutic mineral bathing and the tea culture that defines Makinohara creates a quintessentially Japanese wellness experience where the siliceous waters of the earth complement the polyphenol-rich waters of the tea plant.
