2026 Seijin no Hi, or Coming of Age Day: a Japanese National Holiday Held in JanuaryNEW

Seijin no Hi, or Coming of Age Day, is a Japanese national holiday held on the second Monday of January each year. Historically, it used to be observed on January 15, but since 2000, the date has been shifted to follow the “Happy Monday System,” which designates certain holidays to fall on Mondays.

On this day, local governments typically hold ceremonies to welcome and celebrate those who have reached the age of majority (traditionally 20, though the legal age of adulthood changed to 18 in 2022). Despite that legislative change, most “Coming of Age” ceremonies continue to celebrate 20-year-olds, as it remains the legal drinking age in Japan.

What is the Significance
1. Transition to Adulthood: The age of 20 traditionally marks the legal adulthood in Japan, signifying that individuals can now:
• Vote in elections.
• Legally consume alcohol and tobacco.
• Take full legal responsibility for their actions.

2. Cultural Rite of Passage: The day acknowledges the responsibilities and privileges of adulthood while encouraging young adults to contribute positively to society.

3. Celebrations: Local governments organize coming-of-age ceremonies (成人式, seijin-shiki) to congratulate and inspire young adults. These events often include speeches by local officials and small gifts for participants.
