Mikkabi Onsen Shizuoka is a natural hot spring in Mikkabi, a town on the northern shore of Lake Hamana in western Shizuoka Prefecture, Japan, celebrated throughout Japan for producing the finest mikkabi mikan satsuma mandarins — grown on steep south-facing hillsides overlooking the brackish lake — and known for its distinctive eel aquaculture in the warm lake waters. The naturally chloride-sodium spring waters provide a characteristic coastal-zone mineral soak valued for their warming and skin-softening properties, offering bathers the pleasant combination of lake views and authentic onsen culture in this productive agricultural lakeside community. Soaking in Mikkabi's thermal waters while enjoying fresh local mikan and eel cuisine provides a quintessentially wholesome and flavorful Shizuoka regional experience.
Insider tip — Mikkabi Onsen lies along the northern shore of Lake Hamana, a lagoon famed throughout Japan for its eel farming and freshwater oysters. The gently warm sodium-chloride water at 38 °C makes it a relaxed, family-friendly bath, and the lake views from larger ryokan windows are serene at dawn. Try the unagi (freshwater eel) kaiseki dinner — Lake Hamana eel is considered among Japan's finest.
