Arima Onsen (Hot Springs) is right on the back side of Rokko Mountain where I live. I often visit there with my family and when ever someone comes for a visit, we are certain to take them to Arima at least once! Arima Onsen is one of the oldest hot springs in Japan and often appears in written histories about Japan. The many natural minerals and ingredients found in the waters there are rare worldwide and are really wonderful for ones body. From the many temples and shrines to the beautiful, narrow, old town streets, the entire area is really a wonderful place to walk around and visit.
