"18歳" (18 years old) is a significant age in many cultures, marking the transition from adolescence to adulthood. In many countries, individuals at this age gain the legal rights to vote, sign contracts, and make independent decisions. It is often seen as a milestone in personal development and responsibility. In Japan, turning 18 is particularly important as it signifies the end of compulsory education. Young people may celebrate this age with various traditions, and it is also the age when they can participate in the 成人式 (Seijin Shiki), a coming-of-age ceremony that honors their new status as adults.
