Okinawa’s longest river, the Urauchi River, winds for 24 miles (39 kilometers) through the lush subtropical forest of Iriomote Island. Lined with mangroves, the river is a vital habitat for over 400 fish species and features several waterfalls, including the notable Kanpiuree and Maryudo cascades. Visitors can explore this natural wonder by boat, experiencing the serene beauty of the mangrove forests and the refreshing sound of flowing water. The Urauchi River offers a unique glimpse into the diverse ecosystems of the Okinawan archipelago, proving that there is much more to discover beyond the region’s famous beaches.
