We hang up the carp streamers called "Koinobori" on Children's day in Japan. We display "Koinobori" hoping that their children will grow up healthy and happy. "Koinobori" is a symbol of a family.A big carp is a father, next mom, and children are below. When I worked as a nursery teacher,I was deeply encouraged by seeing the children interacting with the "Koinobori" in a relaxed and lively manner. May "Koinobori" continue to be a traditional Japanese symbol of wishing for children's health and happiness.
