Sunday’s “NHK Special” aired the third and final part of a three-part series focusing on the journey of Homo Sapiens, which left Africa about 80,000 years ago and spread around the world. The program looked into how Homo Sapiens arrived in Japan after overcoming many obstacles, saying that modern man probably sailed in hand-made boats from Taiwan to Yonaguni Island or traveled from Siberia to Hokkaido, inventing sewing needles from animal bone to produce warm clothing as protection from the cold.
