Discover the excitement and tradition of Japan’s Sports Day (Undoukai), where students compete in red vs. white team battles, cheer squads lead the way, and families come together for a day of fun and culture.
Smells Like Team Spirit: Inside Japan’s Traditional Sports Day

It’s autumn in Japan, and the air is filled with the sweet scent of kinmokusei and team spirit! Schools across Japan hold one of the most anticipated events of the year—Sports Day, or as it’s known here, 運動会 (Undokai).
This annual tradition brings together students, teachers, and families for a day filled with friendly competition, spirited performances, and team-building exercises. While the specific events and customs may vary slightly from school to school, the focus remains on physical fitness, teamwork, and fun.
For those unfamiliar with Japanese culture, think of it as a mini Olympics—but much cuter and with more team spirit! And while many countries hold similar events, Sports Day in Japan is uniquely organized, with red and white teams, known as 紅白戦 (Kouhaku-sen), that face off in a series of competitions.
What’s The Big Deal About Sports Day (運動会)?

If you’ve never been to a Sports Day in Japan, it’s hard to imagine just how much excitement and planning goes into it. Here’s a quick breakdown of what you can expect:
Team Divisions: Red vs. White (紅白戦)
Every student is assigned to either the red team (紅組 // aka gumi) or white team (白組 // shiro gumi). The teams compete for points in various events, collectively known as kouhaku sen (紅白戦 ), and the winning team at the end of the day gets ultimate bragging rights!
Group Performances and Relay Races
In addition to Red/White team events, each grade participates in group dances and relay races. Younger students often do simpler, choreographed movements while the older students compete in more intense races. These events are designed to be age-appropriate, so everyone gets a chance to shine, no matter their skill level.

応援団 (Cheer Squad)
One of the most memorable parts of Sports Day for me is the 応援団 (Ouendan), a team of 6th graders who take the lead in cheering for their respective teams. These “cheer squads” aren’t your typical cheerleaders; they put on passionate, often choreographed performances to rally the younger students and encourage team spirit. My daughter’s school even had taiko drummers to rally the crowds!
One thing that particularly stood out to me is that the Red and White team leaders also encouraged their opponent to give their all.
It was almost like saying, “Hey, our team is gonna ganbare the hell out of this Sports Day, so y’all better not insult us by half-assing your participation!”

Likewise, As a rabid Tokyo Revengers fan, I couldn’t help notice the similarities between the ornamental obi-like ribbon that each oeudan leader wears. This ‘ribbon’ is actually called a tasuki, traditionally worn to keep the sleeves of Japanese clothing out of the way—whether it’s for household chores or, in the old days, for wielding a sword.
Modern Changes vs. Traditional Elements
In recent years, some schools have started to modernize their approach to Sports Day.
For instance, many schools have phased out the traditional point system. Some eliminate competitive rankings like 1st, 2nd, and 3rd place altogether. Others have done away with the custom of parents and children sharing lunch on school grounds. (Perhaps this is a lingering effect of COVID precautions.) However, schools like my daughter’s have held onto these traditions, giving the day a nostalgic, old-school charm.
Personally, I believe the balance between competition and teamwork is key.
While each class is split into red and white teams, creating friendly rivalry among students, they also perform group dances together, showcasing unity as a grade. It’s important for kids to feel the joy of winning and, yes, to experience the sting of losing.
But at the end of the day, they’ve made memories, had fun, and learned that whether you win or lose, the experience matters just as much as the outcome.
The Importance of Sports Day for Parents

For parents, Sports Day is more than just watching your child compete. It’’s a chance to see them grow, develop new skills, and build friendships. It’s also a time to connect with other families and share in the experience of cheering for the kids.
Japanese schools these days understand that some parents may be unable to attend Sports Day. My daughter’s school live streamed the entire event through a communication app. They also had special lunch arrangements so children won’t eat alone.
Cultural Insights for Foreign Parents in Japan
For foreign parents who may not be familiar with the event, Sports Day can seem a bit overwhelming at first. Here are a few tips to make the most of it:
What to Expect
If your child has already attended daycare or kindergarten in Japan, you may attend a small-scale Sports Day. Elementary schools turn Sports Day into a performance that’s all made possible with the efforts of teachers, children, and parents/PTA.
The month leading up to Sports Day your child’s physical education class (体育 // taiiku) is exclusively for Sports Day practice. This includes tryouts for the relay runners and dance practice. I suggest preparing an extra set of gym clothes to cut down on laundry.
On the day of the actual event, your child will head to school early to assist with preparing the field.
Lunch
If eating lunch at school is an option, you can send your child to school with their lunch box. Or, you can bring it with you when you arrive. Parents typically bring picnic-style lunches, and you’ll be sitting on blankets, picnic tarps, or folding chairs during the event. Be prepared to cheer along with the other parents—everyone gets involved!
Bring the Sports Day program, school identification, sunscreen, a camera, a portable battery, plenty of water. You might want to bring a foldable umbrella, too, just in case.
Cheering Etiquette
Depending on where you’re from the cheering might be loud and frequent. Here, the parents tend to be more reserved but still supportive. You’ll hear more clapping and coordinated cheers rather than individual shouts. (Please note that I wrote “tend to.” This was certainly not the case at my daughter’s school!)
Dress Code
Wear something comfortable, especially shoes! You’ll be moving around a lot, especially if your child participates in multiple events.
Why Sports Day Still Matters

At the end of the day, Sports Day is more than just a school event. It’s a celebration of community, culture, and the spirit of working together. While some schools are moving away from the more traditional aspects of the day, I’m grateful that my daughter’s school still embraces the nostalgic charm of the event. It’s a day that I look forward to every year, not only as a proud mom but as someone who loves experiencing Japan.
