Located in Rokko, southern Hyogo and on the northern coast of the Osaka Bay, Arima is one of the oldest onsen resorts in Japan. Arima onsen is natural ones that have been used since ancient times when people had no skills of digging in the ground. Presently the digging skills are highly developed, however they are also providing us with hot water full of natural blessings or active ingredients from near the surface in the earth. The spa contains a variety of hot springs including salt-rich spring with a salt content as high as twice that of seawater, carbonated spring with the flavor of soda-pop and radium spring. Arima onsen is very easy to access from the center of Kobe by public transportation so visitors can take a day trip to explore the neighbor.
