Milky Sulfur Spring of Kojigoku

Unzen Onsen Kojigoku Source rises in Kojigoku, among Unzen's steaming "hells," where a bathhouse for toji cures is said to have opened in 1731, and the scholar Yoshida Shoin is said to have visited. Clear as it gushes, the water turns milky white in the air and soothes the skin with a sulfurous aroma. Plentiful in volume, it suits travelers seeking a rustic, unhurried soak in the Unzen highlands.

Why onsen are considered good for Asthma

The benefits of an onsen vary by spring type. Certain spring types are traditionally considered good for Asthma, 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.
