If it doesn't get tweeted, did it even happen? A new report suggests that the World Cup, which kicked off earlier this week and will last through mid-July, is most popular on Japanese Twitter.

According to statistics released by the Adobe Digital Index, Japan beat out the UK, Brazil, Germany, and the U.S. for the most mentions of the global soccer tournament, accounting for 37 percent of all global buzz about the event. Adobe also predicted that this year's World Cup will be most buzzworthy sporting event in social media history, an estimated 500,000 mentions expected per day. That means the tournament could generate as many as 16,000,000 tweets during its month-long run.

“It’s going to surpass the Olympics and Super Bowl,” Adobe Digital Index senior analyst Joe Martin told the New York Times.

No surprise there.
