May 5 - Children's Day in Japan (Kodomo no Hi)

 
Koinobori Song

Yane yori takai koinobori
Ookii magoi wa otousan
Chiisai higoi wa kodomotachi
Omoshirosouni oyoideru

The koinobori are higher than the rooftops
The big black carp is the father
The small golden-red carp is the child
How pleasing it is to swim!

May 5 is Japan's national holiday known as, Kodomo no hi 子供の日 (Children's day). It is a day to celebrate the health and happiness of children. Schools have the day off today!
Until 1948, it was called, "Tango no Sekku 端午の節句", and only honored boys. For many families, May 5 still centers on boys. Some people say that Hinamatsuri (March 3)for girls should become an equal holiday instead of combining them into one.
