One Piece Day is observed worldwide every July 22, celebrating the anniversary of the release of the One Piece manga series, created by Eiichiro Oda. The series, which follows the adventures of Monkey D. Luffy and his crew in search of the mythical treasure known as One Piece, has become a significant part of manga and anime culture. The first chapter was published in 1997, and the series has since grown into a successful media franchise, including an anime series, films, and video games. In 2017, the Japan Anniversary Association officially designated July 22 as One Piece Day, and it is typically celebrated with a livestream featuring announcements about the franchise's future. Additionally, since 2022, a convention dedicated to One Piece has been held in Tokyo, usually in early August, featuring various fan activities such as exhibits, contests, and meet-and-greets.
