Inatori Sea-Warmth Spring

Inatori is a fishing town on a cape of the Izu Peninsula's east coast, known for its hanging hina doll decorations, and grew into a hot spring resort overlooking Sagami Bay as springs were developed in the Showa era. This source rises at a scalding 85.0°C, a weakly alkaline salt spring rich in chloride and calcium. It leaves a thin veil of minerals on the skin that holds in heat, so the warmth lingers after bathing. Strong yet caring, it is a seaside spring in tune with the sea breeze and waves.
