Kodomo-no-Hi is a national holiday in Japan that was known as Boys’ Day from the 9th century, but became a day for both boys and girls in 1948. Today, the day is observed largely with family picnics. Households with sons erect tall bamboo poles outside the home and attach streamers in the shape of carp for each son. The carp supposedly represents the strength, courage, and determination shown in its upstream journeys. The festivities are part of Golden Week, which also includes Greenery Day and Japan Constitution Memorial Day. Discuss
