Children’s Day (子どもの日) and Tango no Sekku (端午の節句) in Japan – A Festival of Strength, Health, and Growth
What is Children’s Day (子どもの日)?
Children’s Day, or 子どもの日 (Kodomo no Hi) in Japanese, is a national holiday celebrated on May 5th as part of Golden Week. This special day is dedicated to celebrating the health, happiness, and growth of children, particularly boys, and to expressing gratitude to parents.
What is Tango no Sekku (端午の節句)?
Tango no Sekku (端午の節句) is the traditional name for the celebration held on the fifth day of the fifth month, rooted in ancient Chinese seasonal festivals. In Japan, it evolved into a day to honor boys, much like how Hinamatsuri (Girl’s Day) on March 3 celebrates girls.
Tango no Sekku is now synonymous with Children’s Day, though the historical and cultural traditions associated with it continue to be celebrated today.
History and Evolution

Tango no Sekku was designated as one of the five seasonal festivals (五節句 – ゴセック) during the Edo period.
Originally focused on warding off evil spirits, it gradually became associated with boys' growth and samurai virtues like strength and courage.
In 1948, May 5th was officially declared Children’s Day, celebrating the well-being of all children, regardless of gender, while maintaining many of the traditional symbols and customs of Tango no Sekku.
