Why are there so many colorful carp flags all over Japan at this time of the year? Because May 5 is a special day for the boys, and is an official holiday in Japan.
So why the carps?
During the Edo period, people celebrated the healthy growth of boys on the 5th of May, when a shogun had a newborn boy.
The Boysâ Festival is called âTango no sekku.â (The Girlsâ Festival is known as âMomo no sekkuâ or âHinamatsuri.â)
In 1948, after World War II, âTango no sekkuâ was given another name: âKodomo no hi,â which means âChildrenâs Day.â
However, people still use both âKodomo no hiâ and âTango no sekku.â
At this time of year, it is common for a big family that has a son or sons to decorate their house with a flag and Japanese armor, helmets, or Musha ningyo (Warrior dolls) to wish for their sonâs health and success.
The carp symbolizes success in life, as the carp turns into the dragon in Chinese ancient fairy tale.Â So Japanese people draw colorful carps on the flags and hang them outside the house, wishing the boys will be strong and successful in their life. People call the carp flags “Koinobori”.
