Turning twenty is an important milestone in Japanese culture, marking the end of adolescence and beginning of adulthood. It is celebrated with a special ceremony called Seijin no Hi, where young adults dress up in traditional kimonos or suits and gather at town halls to be congratulated by local government officials before attending ceremonies with family members or friends. Gifts such as money, jewelry, or household items are given to help them start off their adult lives. Additionally, turning 20 allows access into certain establishments like bars and nightclubs, and may be required for admission into certain universities.
