Isobekan is an old established household, whose members used to act as village headmen since ancient times, and an old established Japanese inn which began operations in the Edo Period. At that time, a thick bamboo grove covered the area, and the village people said the inn nestled into those surroundings was a vision of the "Sparrow's Inn" of Japanese fairy tales.

History of the Isobe Onsen
The scent of the spring water which vigorously gushes up

The Isobe Onsen has a long history. They say it began to flow more vigorously after the great eruption of Mt. Asama in 1783.

This a sodium - chloride - hydrogen carbonate spring with good quality, and is said to be effective for all kinds of diseases. It was even acclaimed by Dr. Erwin Bälz from Germany.

Isobe was originally a mineral spring with low temperature, but it was drilled out in 1996, and now hot water at a temperature of 52.6゚C gushes up at a rate of 150 liters per minute.

At this inn, water from this natural hot spring is piped in from the source.
