The History of Coming of Age Day?

Coming of Age Day, or Seijin no Hi (成人の日), has deep cultural roots in Japan, celebrating the transition of young people into adulthood at the age of 20. The tradition traces back to ancient rituals of the Nara Period (710–794), when young nobles participated in coming-of-age ceremonies known as Genpuku (for boys) and Mogi (for girls). These ceremonies marked the individual's readiness to take on adult roles and responsibilities in society.

The modern Seijin no Hi was first officially celebrated in 1948, shortly after World War II, when the Japanese government established it as a national holiday to recognize young citizens entering adulthood. The first celebration took place in Saitama Prefecture to encourage postwar youth to embrace a sense of hope and responsibility.

Originally held on January 15, the date was moved in 2000 to the second Monday of January under Japan's "Happy Monday System", which was designed to create more three-day weekends.

Today, Coming of Age Day remains one of Japan's most symbolic and picturesque holidays. Young adults gather at local government ceremonies dressed in formal attire celebrating their independence, civic duty and new chapter in life.
