On the second Monday of January, the plaza outside Sapporo Station fills with young women in rented furisode—long sleeves swinging loose, pale blues and reds against the snow—and young men in dark suits or, more often now, in the crisp hakama and haori of another era. They arrive in family cars and on the subway, stamping slush from their boots, hunting for the friends they've known since elementary school. Around them the city is deep in its coldest month: the Odori snow sculptures are still being carved, the smell of miso ramen and grilled seafood drifts out of the underground concourse at Sapporo Station, and every warm doorway seems to pull you inside. This is Coming of Age Day (成人の日, Seijin no Hi), and if you plan a January trip around it, you'll see Sapporo at its most ceremonial and most convivial at once.
Watch the furisode gather for the seijin-shiki
Coming of Age Day is a Japanese public holiday held annually on the second Monday of January under the Happy Monday System. It congratulates and encourages those who reached the age of maturity between April 2 of the previous year and April 1 of the current year—in 2027, that means those who turn 20 during that window. The heart of the day is the coming of age ceremony (成人式, seijin-shiki), held at local and prefectural offices. In Sapporo, the city's ceremony is the anchor of the morning; arrive early to watch the procession of dressed-up twenty-year-olds and their families converge on the venue, and stay for the photographs afterward, when groups spill out into the cold for portrait sessions in the snow.
- Head to the civic offices in the morning for the seijin-shiki itself—this is the public celebration, and the one fixed appointment of the day.
- After the ceremony, expect after-parties among family and friends. These are private, but the streets around the ceremony venue and the station fill with groups moving between them, which is its own spectacle.
- Dress for the cold: January in Sapporo is deep winter, and the formal kimono and suits are worn over thermal layers for good reason.
Eat your way through the station and the markets
Coming of Age Day falls in the middle of Sapporo's coldest stretch, and the city's food is built for it. The basement concourse of Sapporo Station is a network of ramen counters and seafood stalls where families gather before and after the ceremony. Further out, the city's markets are where the day's eating really happens: look for crab, salmon roe, and the hot grilled seafood sold from stalls, and warm up over a bowl of miso ramen—Sapporo's signature—while the snow falls outside. The holiday itself is a day off for most of the city, so the markets and food halls are busy with families celebrating, which makes for a lively, unfussy lunch.
- Start with the ramen and seafood stalls in the Sapporo Station basement concourse—convenient if you're coming from the ceremony.
- Spend the afternoon at the markets for crab, salmon roe, and grilled seafood; this is the season for it.
- Book a table for dinner if you want a sit-down celebration—the day is a family holiday, and restaurants fill up.
See the city in its snow-and-ice season
Coming of Age Day comes just as Sapporo's winter festival season is building. The Odori snow sculptures are still being carved in January, and the city's streets and parks are at their most dramatic in the deep snow. Use the holiday as a day to walk the city: the Odori park corridor, the covered underground walkways that let you cross downtown without stepping into the cold, and the viewpoints over the snow-covered grid. The light in January is low and blue, and the dressed-up crowds against the snow make for photographs you won't get at any other time of year.
- Walk Odori park and see the snow sculptures in progress—January is when the carving happens.
- Use the underground walkways to move between downtown sights without braving the cold.
- Carry a camera: the contrast of furisode and snow is the image of the day.
Time your trip around the second Monday
The date is fixed by the Happy Monday System: the second Monday of January. In 2027, that puts Coming of Age Day in the second week of January, in the heart of Sapporo's winter. Book accommodation early—the holiday coincides with the run-up to the city's winter festival season, and January is a busy month for visitors. Plan to arrive a day or two before so you can settle in, see the city in the snow, and be in place for the morning ceremony. Check the city's official listings for the exact venue and timing of the Sapporo seijin-shiki closer to the date, as these are set by the local office each year.
- Mark the second Monday of January 2027 on your calendar—that's the holiday.
- Arrive a day or two early to acclimatise and explore before the ceremony.
- Confirm the ceremony venue and time with the city's official listings nearer the date.
Make a day of it in the neighbourhoods
Beyond the ceremony, the holiday is a day for the city's neighbourhoods. The area around Sapporo Station and Odori is the natural base: the station for transport and food, Odori for the snow sculptures and the walk through downtown. From there, the covered shopping streets and the market districts give you a full day of wandering between warm interiors and cold streets. If you have an extra day, use it to see the city's winter light and the snow-covered outskirts—but keep the holiday itself for the ceremony, the markets, and the streets full of families celebrating.
- Base yourself around Sapporo Station and Odori for the day's events.
- Wander the covered shopping streets between warm stops.
- Keep the holiday for the ceremony and the city centre; save longer excursions for the days around it.
Start with the calendar: the second Monday of January 2027, and a city in deep snow. Book your room near Sapporo Station, plan a morning at the seijin-shiki, an afternoon in the markets, and an evening walk past the snow sculptures on Odori. Check the city's official listings for the ceremony venue as the date approaches, pack for real cold, and let the day unfold at the pace of a city celebrating its newest adults.
