AI Translation Summary
For the 2025 World Athletics Championships in Tokyo, broadcaster TBS reframed the elite global event as "The World's Biggest Undokai" — Japan's beloved school sports day. Instead of god-like heroes, the athletes became your classmates. A 20-meter Shinjuku billboard was hand-crafted to look like a school bulletin board, complete with rules like "Don't run the hallway in 9.58 seconds." The result: 21M+ social impressions, a record 79.7M+ viewers, and 619,288 people in the stands.
Cultural Context
"Undokai" is a traditional Japanese school sports day that nearly every citizen has taken part in, making it a shared nostalgic memory. "9.58 seconds" is Usain Bolt's 100m world record, wittily swapped into the familiar school warning "don't run in the halls."

Summary
To reignite public interest in track & field for the Tokyo 2025 World Athletics Championships, we transformed the elite global event into "The World's Biggest Undokai" (Japan's traditional school sports day). By framing god-like athletes as familiar "classmates," we closed the distance between athletes and fans. The campaign generated 21m social impressions, achieved a record-breaking 79.7m+ viewership, and attracted 619,288 attendees, successfully turning the championships back into a massive national celebration.
Strategy
Traditional sports ads often deify track & field athletes, portraying them as remote, god-like figures. This created an emotional distance that lowered public interest. Our strategy shifted the perspective based on a key insight: fans feel a deeper emotional connection when they view elite athletes not as distant heroes, but as their own "classmates." We tapped into cultural nostalgia by utilizing "Undokai," a school sports event every Japanese citizen has participated in and holds memories of, creating an immediate sense of familiarity and collective ownership.
Execution
We brought the "Undokai" spirit to life through hand-crafted, nostalgic touchpoints. At Shinjuku Station, the world's busiest train hub, we created a 20-meter billboard styled entirely like a school bulletin board with hand-made decorations. We also decorated Tokyo's Symbol Tower to mimic a school festive takeover and aired TV commercials themed around nostalgic "Undokai home videos." Creative copywriting like "Don't run the hallway in 9.58 seconds" humorously blended world records with everyday school rules.
Results
The campaign successfully turned the elite sports event back into a beloved national festival, achieving unprecedented engagement across all metrics. It generated over 21 million social media impressions and achieved a media reach of 4.6 million. Broadcast metrics reached historic highs, with a record-breaking viewership of over 79.7 million people. Furthermore, the event itself drew a record-breaking live attendance of 619,288 spectators, proving that turning athletes into classmates successfully reignited a nation's passion.
