May 5th is Children’s Day in Japan, when traditional carp-shaped koinobori are flown in the air for children in the hope that they will grow up healthy and strong.
These carp patterns are usually drawn onto paper, cloth or unwoven fabric.
Since 1995 when the event started, hundreds of koinobori are gathered at the famous Niyodo River, where the townspeople and people around Japan come together to enjoy this annual celebration. The koinobori designs are all on unwoven cloth made locally, which are durable enough to be flown in the wind and ‘swim’ in the streams of Niyodo River. This unwoven cloth is an “in-between” of paper and cloth, since the synthetic fibers are bound together randomly like the characteristic of Japanese papermaking.
