Kuei Unagi Onsen

Kuei Unagi Onsen is a public bathhouse in the Unagi Onsen hamlet on the shore of Lake Unagi, in Narikawa, Yamagawa, Ibusuki City, Kagoshima Prefecture. It has served as a local hot spring retreat since the Edo period and is still run by the community as a simple, unpretentious bathhouse. The hamlet also has natural steaming spots fed by hot ground vapor, where visitors cook onsen eggs and other food.

The spring is a simple sulfur spring with a source temperature of 88.8 degrees Celsius. Because the water is extremely hot, it is mixed with water to bring it to a bathable temperature and then supplied in a flow-through (kakenagashi) style. The bath is on the hot side, and the spring is traditionally recommended for skin conditions, neuralgia, and recovery after illness.

The facility has indoor baths only, one for men and one for women, in a plain and simple building. Admission is 300 yen for adults (junior high school age and older), 100 yen for elementary school children, and 50 yen for infants. Hours are 8:00 to 19:00 from October to May, and 8:00 to 13:00 and 15:00 to 19:00 from June to September. It is closed on the first and third Monday of each month (open if the Monday is a national holiday). Parking is available.
