Coming of Age Day, known in Japan as Seijin no Hi (成人の日), is one of the country’s most heartwarming annual celebrations. It honors young adults stepping into adulthood, traditionally at age 20. Since April 2022, the legal age of adulthood in Japan has been lowered to 18. This change grants new rights, such as the ability to sign contracts, obtain credit cards, and marry without parental consent. Certain age-restricted activities, like drinking alcohol and smoking, still require turning 20, meaning that the importance of this special day still stands for many young Japanese people.
Seijin no Hi falls on the second Monday of January and brings communities together in a colorful display of tradition, pride, and optimism for the future.

The Significance of Adulthood in Japan
Turning 18 now marks legal adulthood, but many communities continue to celebrate Coming of Age Day for 20-year-olds. This ceremonial focus recognizes both social maturity and cultural tradition. Reaching adulthood signifies new responsibilities and freedoms, from civic participation like voting to personal independence in everyday life.
But this isn’t all there is to this event. The day also celebrates growth supported by family, school, and society. It is a chance to reflect on youth and step confidently into a future as an adult.

What Happens on Seijin no Hi?
Across Japan, local governments host ceremonies called Seijinshiki (成人式). These Coming of Age Ceremonies take place in community centers, city halls, and public halls. Young adults gather dressed in their finest attire and are welcomed with congratulatory speeches, local performances, and sometimes small gifts.
Traditional Attire
One of the most visually striking aspects of Seijin no Hi is the clothing. Many women wear a furisode (振袖, long-sleeved kimono) with bold colors and elegant patterns, symbolizing youth and unmarried status. Men often wear a formal kimono with hakama (袴, pleated trousers), though suits have become increasingly popular.
Walking through towns filled with young adults in traditional attire creates a vibrant atmosphere. Families and friends capture countless photos, while beauty salons and kimono shops buzz with activity.
Community Spirit
Seijinshiki also serves as a reunion. Many participants return to their hometowns for the ceremony, reconnecting with classmates and neighbors. The day is filled with laughter, nostalgic conversations, and a strong sense of community.

Seasonal Context: Midwinter Beauty
Coming of Age Day falls in January, one of Japan’s coldest months. Crisp air, clear winter skies, and occasional snowfall create an enchanting backdrop for the celebrations. The colorful furisode kimonos stand out even more against the winter scenery, offering excellent opportunities for photography and cultural observation.
The holiday also coincides with other New Year traditions, such as hatsumōde (初詣, first shrine visit of the year), seasonal foods, and a general atmosphere of renewal, adding to the overall magical feel of the whole event.

A Celebration Rooted in History
Coming of Age Day has deep historical roots. Ceremonies like genpuku (元服) for boys and mogi (裳着) for girls marked the transition from childhood to adulthood centuries ago. The modern Seijin no Hi that we know today was actually established in 1948.
Even with the legal shift to 18, the ceremonial focus on 20-year-olds continues in many places across the country. This balance between legal change and cultural tradition highlights how Japan honors life milestones thoughtfully and intentionally.
