Nanyo, Ehime: Water for Life and Fun

The Nanyo area of Ehime Prefecture is blessed with abundant water. It lies on the west coast of Shikoku Island, looking out on the Uwa Sea and bathed by the warm Kuroshio Current. Along the coast, rainfall levels are typical of most of Japan. But inland, the Onigajo Mountain Range receives substantially more rain, with some 2,700 millimeters observed each year. Much of that water flows quickly down to the sea, molding the topography of the area. Offshore, the warm water from the Kuroshio Current mixes with the nutrient-rich fresh water from the mountains, making an ideal habitat for coral and a remarkable variety of marine life. On this episode of Journeys in Japan, Michael Keida follows the flow of this water, from the mountain slopes down to the ocean bed.
