As the Philippine Sea Plate subducted, these mineral-rich waters were pushed to the upper mantle, and after evaporating, they surged upward from 60 kilometers underground as one of the world's rarest geological hot springs. Arima Onsen's spring water is renowned as Japan's most mineral-concentrated. The reason, it is said, is that within a 6-million-year-old serpentine rock layer lies ancient seawater from the time when humans first began to walk upright — and the salinity of Arima Onsen's water is a perfect match. Truly a hot spring that transcends time and space.— Package Info —[Day-trip bathing package]• Bathing + Kobe Beef Sukiyaki Set + Soft Drink • Bathing + "Taiko Yume Jyuraku" + 5-minute Dr. Fish package • Bathing + "Taiko Yume Jyuraku" + 5-minute Dr. Fish package + Soft Serve Ice Cream The paid bedrock bath "Taiko Yume Jyuraku" uses a wide variety of bedrock not found in the free bedrock bath, making it extremely popular.
