‘Koinobori’ means ‘carp-streamer kite’, and the carp was chosen as the symbol of Children’s Day because the Japanese consider it the most spirited fish, full of energy and power to fight its way up rapidly-flowing streams. The koi fish symbolises courage and determination.┬áThese traits are usually hoped for boys, traditionally families hang koinoburi to honor their sons. The tradition has evolved to become Children`s day to wish for good health and well being of all children.
