Inunakiyama Hot Spring is the most secluded hot spring in Osaka Prefecture. The water of this pure sodium hydrogen carbonate spring is almost completely transparent, and is effective for rheumatism, neuralgia, gastrointestinal diseases, and skin diseases as well as skin beautification. Although the water feels thin, it leaves the skin silky smooth. The hot spring is popular in spring when the mountain cherries bloom and in fall during autumn foliage season, but it is very beautiful at any time of the year.
