Antonio Inoki is arguably Japan's most famous professional wrestler in history (think Hulk Hogan levels), and he is currently a politician in that country.  Inoki founded New Japan Pro Wrestling, one of the oldest and most important wrestling promotions.  Back in 1995, Inoki led another wrestling tournament in North Korea, with the main event being THE NATURE BOY RIC FLAIR vs. ANTONIO INOKI.  Some sources list the attendance for that event as the largest in the history of the sport (around 190,000).

 Here is a short video from the match:
