Classification

Calcium-Hydrogen Sulfate spring

An ultra-acidic calcium sulfate spring (pH 2.4) rising at 90.7 °C, among Japan's hottest natural sources. The water carries a faintly milky white, lightly cloudy appearance at the wellhead with a strong sour and metallic tang, sharp enough to sting on contact. Metasilicic acid at 396 mg/kg adds a noticeable silica film, typical of the Myoban onsen field famous for its skin-conditioning waters.

About

A homely ryokan hot spring with the scent of sulfur. Located in the sulfur-scented Myoban area, this is a traditional homely ryokan hot spring. There are two baths, each with a different spring quality. One of them has gray water with a strong acidity of pH 1.8, which is quite unique. Soap does not lather here. The mud settled at the bottom of the bathtub is also distinctive. You can relax and enjoy it privately!

485. Yumotoya Ryokan, Beppu We visited various private baths on different days for day trips. The price was 500 yen per person. Day trip hours are from 10:00 to 14:00. They stamp the Beppu Onsen passport. 1. Private indoor stone bath. Breathing inside is comfortable. - In April, the water was clear, slightly cloudy with a gray tint, temperature 48°C; - In January, the water was cloudy gray, temperature 46°C. 2. Private indoor rectangular bath. The water was cloudy white-gray with a proper stale onsen smell. Temperature 44°C. Breathing inside is comfortable. 05.04.2025 04.01.2026 31.03.2026
