Seventy miles off the coast of mainland Japan is the small island of Okinawa, home to some of the most unique seaweed in the world. Mozuku is a rare underwater delicacy found off the mainland coast. Each fall, farmer Tadashi Oshiro uses a special technique to sustainably harvest the seaweed. His one-of-a-kind farming methods were passed down to him by his father, using a process that allows the mozuku to grow without creating additional waste. And although changes in the environment leave the future of mozuku uncertain, Tadashi continues to uphold his family's legacy. This video is from the Planet Earth collection of Great Big Stories
