One of Tokyo’s largest koinobori festivals takes place at the foot of Tokyo Skytree, with 1,000 carp streamers fluttering in the air. The traditional koinobori carp streamers are put up to celebrate Children’s Day, which happens every May 5 during Golden Week.
If you visit the Postal Museum on the ninth floor, you can participate in a fun workshop to make your own koinobori from used stamps for ¥300 (¥150 for high school students and under) until May 5. Additionally, other activities will also be taking place at venues around Tokyo Skytree Town including a fake food workshop at Ganso Shokuhin, a workshop to make hand-painted carp streamers at the Tokyo Solamachi East Yard, and a carp streamer candy sculpting workshop at the Asakusa Amezaiku Ameshin store.
