Japanese Professional Snowball Competitors Dream of the Olympics

By Elizabeth Webb for The J-Pop Exchange

Near the base of a volcano in Sobetsu, Hokkaido (Japan), more than 1,000 helmeted competitors recently charged onto the snow-covered battlefield for the 37th Showa-Shinzan International Yukigassen, where childhood play is transformed into a high-stakes, precision sport, and perfectly round snowballs fly across the sky.

The annual tournament, which this year landed on February 21-22, 2026, showcases yukigassen as a fast-growing, highly strategic sport with ambitions of Olympic recognition. This year’s champions were NMT, a team from northern Hokkaido.

Snowball fights (known as yukigassen in Japanese) are a familiar winter pastime for children in snowy regions all around the world. But in Sobetsu, they’ve evolved into a serious competition, complete with corporate sponsors and teams traveling from across Japan and abroad.

So how does a game work? And what are the rules?

Each team has seven players, so there are 14 players total in an area roughly one-third the size of a football field. A team flag stands at each end of the field, and low barriers provide cover for players. Teams are given 90 machine-created snowballs per set, and each set lasts just three minutes.

People unfamiliar with the sport can somewhat compare it to paintball or laser tag, just colder. And probably more painful.

“When you get hit, it hurts,” Toshihiro Takahashi, a 48-year-old civil servant, told The Japan Times. “But it's mostly your pride that takes the blow.”

A team wins a set by either capturing the opposing team’s flag or eliminating all seven opponents with snowball hits. The first team to claim two sets wins the match.

With 180 snowballs in play per set, oversight is not easy. Each match requires eight referees to monitor hits, boundaries, and flag captures.

The idea to formalize yukigassen began during a difficult chapter in Sobetsu’s relatively recent history. Once known for its hot springs, the town’s tourism industry suffered after the 1977 eruption of Mount Usu. Searching for a way to revive the community, residents found inspiration in a simple sight: tourists laughing during a snowball fight. So the first organizers thought: “What if this childhood game could help put Sobetsu back on the map?”

The concept surprisingly caught on quickly. Within three years, the sport spread to Australia. Finland established a national federation in 1995, and then the game started to gain traction throughout Scandinavia, Russia, and North America. Today, yukigassen is played in 13 countries.

With its international growth, organizers are now aiming even higher… Olympic status.

Ironically, to achieve that goal, the sport has had to move beyond snow. Specially designed artificial snowballs allow matches to be played indoors or even on a beach, transforming a seasonal snow-covered pastime into a year-round global competition.

In 2013, enthusiasts set up the International Alliance of Sports Yukigassen to raise the level of competition and to spread the game around the world. The Japanese are hopeful that, one day, snowball fights will become an Olympic Winter Sports event.
