一句：Kodomo no hi, also known as Japanese Children's Day, is celebrated on the fifth day of the fifth month each year. This festival, originally intended for boys, has been renamed to include both sexes. It is a public holiday where the sky is adorned with carp-shaped kites, floating on the breeze from bamboo flagpoles or rooftops.二句：Also referred to as 'Sobu no Sekku' (Iris Festival) or 'Tango no Sekku' (May 5th Festival), Children's Day is traditionally a celebration of sons' future prosperity and well-being. However, in more recent years, it has been alleged to have been adapted to include girls as well, since the Girls' Festival in March is not a public holiday.三句：One of the festival's names, the Iris Festival, originates from a 12th-century belief that the long, sharp leaves of the iris resemble swords. Consequently, placing iris leaves in a boy's bath was believed to imbue him with a martial spirit.四句：The iris leaf tradition symbolizes the desired qualities of courage and strength in boys as they grow. This is just one of the numerous symbols associated with Children's Day, most of which convey themes of vitality, health, and success.五句：The array of symbols encapsulates the essence of this day, reflecting the importance of nurturing strength and well-being for a prosperous future.
