Today is the celebration in Japan for all Children In Japan, Kodomo no hi, or "Children's Day," and is celebrated every year on May 5. On this national holiday, children are respected and honored for their individual strengths and happiness is wished upon them. Children's Day was originally known as Tango no Sekku  (literally nearing the seventh sign of the chinese zodiac, but usually translated as Boys Day) and was a celebration for boys. The holiday was officially changed to celebrate the health and growth of both girls and boys in 1948.  Kodomo no hi is particularly well known for the unique traditions and decorations that are associated with the celebration of the holiday.

On Kodomo no hi, or cloth carp streamers, are flown on poles outside of public buildings and private houses to bring luck and good fortune to the children inside. Koi fish, or Carp, are believed to be strong, spirited fish and are revered for their determination in fighting as they swim upstream and through powerful waterfalls. Koinobori symbolize the desire for children to become brave and strong indivuduals.
