"Kodomono hi" is a Japanese phrase that translates to "Children's Day" in English. It is a national holiday in Japan celebrated on May 5th each year, and it is also known as "Tango no Sekku" in Japanese.
The holiday is dedicated to the happiness and well-being of children and is celebrated with various traditional customs and activities. Families often fly colorful carp-shaped streamers called "koinobori" outside their homes, representing strength and perseverance like a carp swimming upstream.
They also decorate their homes with traditional armor and warrior dolls, called "samurai" or "kabuto.“ Families may also eat traditional foods like "kashiwa mochi," a sweet rice cake wrapped in oak leaves.
