The Central League and Pacific League formally announced complete details on game length limits for the 2011 season. They are as follows:
- If two teams are still tied after playing 12 innings, the game will end in a tie. For the 2011 season, once the length of the game hits 3 hours and 30 minutes, games will not advance into any new extra innings. The limit will begin the moment the game actually begins and not the scheduled start time.
- The 3 hour 30 minute limit includes delays caused by things like rain, wind, fog, and any other reasons that might temporarily stop play.
- Double headers will not advance into any new extra innings if they hit the 3 hour 30 minute mark.
- If a game ends early because a blackout, the game will be called.
Both leagues also announced that they will hand out Nippon Seimei Monthly MVP Awards and JA Go Go Awards this season.
