The focal point of Wrestling World 2001 was a tournament to crown a new IWGP Heavyweight Champion, which accounted for five of the nine matches on the show. No other championships were defended in 2001, marking the first year that only one title was on the line. The show saw Toshiaki Kawada wrestle twice; Kawada had previously been one of the main event wrestlers of NJPW's biggest rival All Japan Pro Wrestling.
The January 4 Tokyo Dome Show is NJPW's biggest annual event and has been called "the largest professional wrestling show in the world outside of the United States" and the "Japanese equivalent to the Super Bowl".[2][3]
