Watch the Year Turn Twenty in Umeda and Namba
It is the second Monday of January, and Osaka is full of young people who have dressed for a photograph. In Umeda, furisode sleeves in scarlet and indigo sweep past the glass of the station concourses; in Namba, knots of friends in black suits and dark hakama stand in the cold, comparing hairstyles and lining up for pictures. Somewhere behind you a takoyaki griddle hisses and a vendor calls out over the crowd. This is Seijin no Hi, Coming-of-Age Day, and the city has been doing it this way for decades.
The holiday is a national one, observed on the second Monday of January. It was established as a public holiday in 1948, originally fixed to 15 January, and moved to the second Monday in 2000 under the Happy Monday system. That means in 2027 it falls on the second Monday of the month — check the calendar before you book, and build your trip around that long weekend.
Find a Seijin Shiki Ceremony
The centrepiece of the day is the seijin shiki, the coming-of-age ceremony, held at city halls, municipal and ward offices, and other official venues, usually in the late morning. Osaka is a city of wards, and each has its own. The participants are those who reached adulthood between 2 April of the previous year and 1 April of the current year; they receive invitations by mail from their city of residence, and that invitation is required for venue entry. Officials give speeches welcoming them into adulthood.
- Ceremonies run in the late morning — arrive early enough to watch the arrivals, which is where the real spectacle is.
- Entry is by mailed invitation, so you will be watching from outside rather than sitting in the hall. The forecourt, the queue, and the photographs afterwards are the part a visitor can share.
- Note that the age of adulthood was lowered from 20 to 18 on 1 April 2022. At 18, Japanese citizens may vote, apply for credit cards, drive, obtain a 10-year passport, and marry without parental consent — but drinking, smoking, and gambling remain legal only from age 20. In practice many still celebrate at 20, since 18-year-olds are typically finishing high school and cannot legally drink.
Follow the Furisode to a Shrine
In the afternoon, the new adults disperse to shrines and temples to pray for blessings and take photographs. This is the hour to be out on the street with a camera. Women wear furisode, the formal kimono with long draping sleeves traditionally worn by single adult women — Coming-of-Age Day is the first occasion they may wear one. The full outfit includes an up-do with floral accessories, a small kimono-fabric bag, white tabi socks, zōri sandals, and often a short white shawl against the January cold. Men wear a black Western suit, or a black or dark kimono with hakama trousers.
Buying a furisode can cost tens of thousands of dollars; most people rent, for hundreds to a few thousand dollars, which is why you will see so many of them converging on the same photogenic spots. Some shrines offer Seijin-no-Hi packages that bundle clothing rental, a photoshoot, and prayers. Meiji Jingu in Tokyo, near Harajuku Station, is the famous example of a shrine drawing large crowds on the day — in Osaka, head for the shrines and temple grounds in your ward and you will find the same ritual at a smaller, more local scale.
Eat, Drink, and Stay Out in the Evening
By evening the formal wear loosens. Group outings are the tradition — Tokyo Disneyland is a popular choice for the Tokyo crowd — and so is drinking at an izakaya, which is newly legal for the 20-year-olds among them. In Osaka you are in the right city for it.
- Build your evening around the izakaya and street-food districts: the stalls and standing bars around Namba and Dōtonbori, and the lanes of Umeda's backstreets. January is cold, which makes a hot griddle and a warm counter the correct destination.
- Expect the takoyaki and okonomiyaki stalls to be busy with groups in suits and kimono, and expect the drinking to run late.
- If you are travelling with someone turning 20, remember the legal line: drinking is permitted from 20, not 18, regardless of when they attended a ceremony.
Know How the Day Is Timed
Structure your day around three movements. Late morning is for the ceremonies at the ward offices and city halls. Afternoon is for the shrines, the photographs, and the slow walk between them while the light holds. Evening is for the izakaya and the group celebrations. The holiday itself is fixed to the second Monday of January, so the weekend around it is the practical window for a visit — book accommodation in Osaka early, as this is a domestic travel occasion as much as a local one.
One caveat from the wider Japanese pattern: in areas of heavy snowfall, such as Niigata and parts of northern Japan, ceremonies are sometimes held later, during Golden Week in May or at Obon in August. Osaka does not have that problem — expect the standard January date.
Plan Around the Second Monday
Find out which Monday the second week of January 2027 gives you, put it in the calendar, and work backwards: flights into Kansai, a hotel within walking distance of a ward office or a shrine, and a free afternoon with nothing booked. The day rewards wandering more than scheduling. Watch the arrivals in the morning, follow the furisode to the shrine steps in the afternoon, and let the evening take you to whichever izakaya still has a seat.
