Kuroshio Onsen, in Makinohara on the Shizuoka coast, takes its name from the nearby Kuroshio current and heats sodium-chloride thermal water to 39°C, with an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — 'Kuroshio' (Black Current) Onsen is named for the powerful Pacific ocean current that warms Japan's coast — a fitting name for a hot spring in Shizuoka, where the Kuroshio's influence shapes the climate of the famous tea-growing Makinohara plateau. Warm, sodium-rich artesian waters.
