Uminchu, literally "people of the sea", is the name for the fishermen of beautiful Kumejima in Okinawa Prefecture. Filled with coral, tropical fish, and the tuna varieties that swim the Kuroshio Current, the sea around Kumejima has a rich diversity of life. Many locals make their living fishing, and use traditional skin-diving skills and pole-fishing techniques that have been passed down for generations. Get to know the young people training to become uminchu, and the older fishermen who are mentoring them, eager to share advice. This is an island journey to meet people who have truly embraced the sea.
