Gempuku is a traditional Japanese coming-of-age ceremony that marks the transition of a young person, typically around the age of 15, into adulthood. This event often involves a formal celebration where the individual dons a kimono and participates in rituals that signify their new status in society. During Gempuku, the young person may receive blessings from family and community members, and they often take on new responsibilities. The ceremony has historical roots in the samurai culture, where it was an important milestone for boys, but it has evolved to include girls as well, celebrating their maturity and readiness for adult life.
