Sanogawa Onsen

Sanogawa Onsen is a sulfur hot spring in Minamikoma where natural thermal waters rise from deep underground sources in the Yamanashi mountains. Separate indoor and outdoor bathing facilities serve men and women, with towel rentals and basic amenities provided.

The thermal waters have served local communities since ancient times as a traditional healing and bathing site. Over centuries, this spring has remained an important place for relaxation and wellness practices.

Bathing here follows traditional Japanese customs where visitors remove their shoes, shower thoroughly before entering, and then immerse themselves in the shared mineral pools.

Visit during early morning or late evening hours to avoid crowds and enjoy a more peaceful experience. Bring your own toiletries since basic amenities are minimal, though towels are available for rent.

The mineral composition creates a distinctive white crust on surrounding rocks, visibly marking the spring's geological character. This natural deposit reveals the rich mineral accumulation that the water has gathered over time underground.
