Salt Spring Above the Islands

Rising at Kinoe on Osakikamijima, an island reached only by ferry, this spring once served a public lodge loved by islanders and sea travelers. Saltier than seawater and rich in calcium with a trace of radon, it is a powerful water for those who want to warm themselves slowly while gazing over the scattered islands.

Why onsen are considered good for Rheumatism

The benefits of an onsen vary by spring type. Certain spring types are traditionally considered good for Rheumatism, 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. Each onsen page shows mineral visualisations, bathing tips and booking options.
