Quick answer: Coming of Age Day (Seijin no Hi) is a Japanese national holiday held on the second Monday of January. Local governments hold ceremonies for new adults, many of whom wear furisode kimono, hakama or suits, and the legal adult age has been 18 since 2022.

On a crisp January morning in Japan, train stations and city halls fill with young people in bright long-sleeved kimono, sharp suits and traditional hakama, all heading to the same celebration. This is Coming of Age Day, known in Japanese as Seijin no Hi, a national holiday dedicated to honoring those who have recently become adults. It is one of the most photogenic days of the Japanese calendar and a joyful window into family, fashion and tradition. This guide explains when it happens, how it began, what people wear, what the ceremonies are like, and how visitors can enjoy the day respectfully.

What Is Coming of Age Day in Japan?

Coming of Age Day is a public holiday held on the second Monday of January each year. Under Japan's "Happy Monday" system, this creates a long weekend, so families and friends have time to gather. The purpose of the day is to celebrate young people who have entered adulthood and to encourage them to become independent members of society. People who reached adulthood between April 2 of the previous year and April 1 of the current year are the group traditionally honored.

The ceremony itself is called seijin-shiki. It is organized by local municipalities rather than the national government, so the style differs from city to city. Most events take place in the morning at a city hall, ward office, concert hall or gymnasium, and they typically include speeches from local officials, a congratulatory message and sometimes a small gift. Afterward, the new adults often reunite with old classmates for photographs, meals and parties.

How Did Coming of Age Day Begin?

The roots of the day go back to ancient rites of passage known as genpuku, which marked the moment a young person was regarded as an adult. Genpuku dates to the Nara period (710 to 794) and was practiced at the imperial court and among the samurai class. Historically, boys and girls reached adulthood at much younger ages than today, and these ceremonies often involved changes of hairstyle or clothing to show a new status.

The modern celebration is usually traced to a youth festival held in 1946 in the town of Warabi in Saitama Prefecture, which aimed to encourage young people in a hopeful new era. The idea spread nationwide, and the national holiday was established in 1949. In 2000 it moved to the second Monday of January under the Happy Monday system, which is why the date shifts from year to year. The legal age of adulthood in Japan was lowered from 20 to 18 in 2022, though alcohol and smoking are still restricted until age 20, and each municipality decides how to handle the ceremony. Some invite 18-year-olds, while many continue to celebrate those turning 20.

Looking at the long history helps explain why the day feels so meaningful. In earlier centuries, young people were regarded as adults at around 15 for boys and 13 for girls, and the legal age of adulthood was set at 20 in 1876. Moving it to 18 in 2022 changed the law, but the spirit of the celebration stayed the same: it is a day to recognize growing up, to thank parents and teachers, and to look ahead with hope.

What Do People Wear on Coming of Age Day?

The most striking sight is the furisode, a formal kimono with very long, flowing sleeves that is traditionally worn by unmarried young women. Furisode come in vivid colors and rich patterns, often with flowers, cranes or gold embroidery, and they are usually paired with a fluffy fur or feather stole, an elegant obi sash and carefully styled hair. Many families rent furisode for the day, since buying one can be expensive, and professional dressers and hair artists are booked well in advance. Photo studios also offer special shooting sessions, so many people take portraits before or after the ceremony.

Young men wear either dark suits or traditional formal wear, which includes a kimono jacket and hakama (wide pleated trousers). In the past, hakama were the standard formal wear for men on this day, but modern suits are now more common. Some groups choose bold outfits to stand out in group photos, and the whole street scene feels like a celebration of personal style.

Where Can Visitors See the Celebration?

The official ceremonies are intended for local residents, but visitors can enjoy the festive atmosphere around the venues. Public spaces near ceremony halls often see groups of friends in their finest clothes taking photographs. In Tokyo, areas near major municipal halls, train stations and popular parks tend to have colorful crowds in the morning. Shrines are popular photo spots too, and some local attractions may host special events for new adults.

The best approach is to be a polite observer. If you want to take photographs of someone in furisode, it is courteous to ask first and to thank them afterward. Many young people are happy to pose, but the day is for them and their families, so respect their space. Be careful not to block narrow sidewalks or entrances, and keep your distance if a group is busy having a family portrait taken. As of autumn 2026, event arrangements differ across cities, so check the local municipal website for announcements about public celebrations nearby.

What Else Should You Know About the Day?

January is cold in much of Japan, and beautiful kimono are not always warm, so you may see people wrapped in shawls and heat packs between photos. Furisode are also delicate, which is why you might notice people moving carefully on stairs and trains. If you are traveling on the holiday, keep in mind that it is a three-day weekend, so transportation, restaurants and attractions may be busier than usual, and some shops and offices are closed.

Attendance numbers at ceremonies have declined from their peak in the 1970s, but the day remains a cherished milestone. Many families treat it as a moment for gratitude, and it is common to hold a family dinner or visit a shrine to give thanks for the years of growth. For many, the photographs from the day become treasured keepsakes.
