Bandai Atami Onsen is a hot spring town in Fukushima, Japan. The water leaves the ground at 53°C, hot. Officially the water is classed as simple spring and sulfur spring.
Mild and low in dissolved minerals. Usually clear and gentle on the skin, which is why these baths are often recommended for first-timers.
The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.
