Do you know the Japanese anime movie Kimi no Na wa, or Your Name? The hero and the heroine each wear kumihimo. This key item shows us the basic theme of the story: musubi. This Japanese word means the ties between people over time and space. Thanks to the movie, young people around the world as well as in Japan became interested in the art of kumihimo. Now some of them even make kumihimo by themselves. The handicraft of kumihimo has a long history. How did the tradition of tying develop? How did musubi begin to express the connections between people?
