Tea-Brown Carbonated Spring

Nigoriyu bubbles up beside the Seri River in Nagayu Onsen, a village famed for carbonated springs, and was once known as the "high-temperature Ramune spring." Clear at the source, its iron content oxidizes into a tea-brown cloud in the bath, giving the spring its name. Around 40°C, the water lingers on the skin with fine bubbles and a silky, clinging feel, suiting bathers who want a long, gentle soak.

Why onsen are considered good for Hypertension

The benefits of an onsen vary by spring type. Certain spring types are traditionally considered good for Hypertension, and the corresponding indications are listed in the legally required onsen analysis sheets. my Onsen Techo ranks the onsen best suited to your symptom and area based on analysis-sheet data, which is mandated for display under Article 18 of Japan's Hot Spring Act.
