四季美谷温泉 is a hot spring town in Tokushima, Japan. The water leaves the ground at 16.7°C, cool enough that the baths here are usually reheated. It measures pH 9.2 — strongly alkaline. Officially the water is classed as sulfur spring. Its sources put out around 51 litres a minute. 1 inns take visitors here with room for about 44 guests.
The classic rotten-egg smell and milky white water. It can tarnish silver jewellery, so take it off.
