Today is Children’s Day (子供の日) in Japan. Traditionally this day was mostly for boys and sometimes known as Boys’ Day, with the ひな祭り (Doll Festival) on March 3rd as the counterpart for girls, but today it is officially meant for boys and girls alike. Children’s Day is celebrated with big carps made of paper (or more robust materials in modern times) flying in the wind, wishing that the children grow up as strong as big and healthy carps.
I took this picture at Yodomibashi in Sendai a few days ago, close to at least two schools that I know of. And the koi carps in Japanese ponds are pretty big, so that’s one seriously good wish! 😉
