Rules for watching baseball games

The Tokyo Dome would like the audiences to cooperate in the following matters in order to ensure that they can enjoy events safely and comfortably.

Baggage inspection and body search at the entrance

We may also conduct a body search or inspection by a metal detector to strengthen the security in response to a social condition.

  • - The contents of small flags, cheering flags and cheering boards should be limited to the ones used to cheer for the team and players.
    (The contents which are contrary to public order and morality, or include slanders are prohibited as well as the designs which the organizer decides are not appropriate for cheering baseball.)
  • - Other cheering implements prescribed in the “Policies for Watching Games” are not allowed as well as the cheering implements which the organizer and Tokyo Dome decide hinder the proceeding of an event and management of the facility.


  • - In the Tokyo Dome, smoking is prohibited in both the audience areas and concourse except a few smoking rooms.
    Please use a smoking room or designated smoking area (outside the gate) if you smoke.
    The smoking rooms may not be available for some events.

Cheering while watching the Giants’ games

  • - Please refrain from cheering for the Giants in the visiting rooters’ seats and cheering for the visiting team in the Giants’ rooters’ seats behind left field not to cause trouble between members of the audience.
  • - The reserved seats behind left field (except the visiting rooters’ seats and the Giants’ rooters’ seats behind left field) are the area where both Giants fans and visiting team fans use. Please respect each other in order to enjoy watching the game.
  • - The outfield stands, Orange seats, rooters’ seats behind the infield are the areas where you can stand up to cheer.
  • - The approximate size of the “Other supporter goods” described above are 700 mm long and 500 mm wide. Please refrain from using a hard material.
    In the Excite Seat, this type of cheering instrument is prohibited for use from a safety perspective.
  • - Please refrain from any actions to demean the other team and possibly to provoke the fans of the other team (such as breaking, dragging and stomping the mascot goods of the other team) in and outside the stadium not to cause trouble.


  • - Re-entry is not allowed (this shall not apply to the cases where the organizer approves). But Re-entry has been allowed for the official Giants’ games since 2006.
    (Prescribed procedures are required in the case of re-entry.)

Injury by a batted ball or broken bat

Watch out for batted balls and broken bats!

  • - In professional baseball games, attendants blow an “alarm whistle” to warn of danger when a foul ball or a home run ball during practices flies.
    Please pay careful attention to the direction of a ball.
  • - Balls and goods can be thrown in the stands as fan service. Please pay careful attention not to get hurt (before a game starts, between innings, when a home run is launched or after a game ends).
    It is very dangerous to chase a ball. Please do not leave your seat when balls are thrown in.
  • - A broken bat or its debris may fly into the stands when batting a ball. Please pay careful attention, too.

* In the case that you get hurt from a batted ball, throw-in service or a broken bat, we will give you first aid, but we are not responsible any further. Please let the attendant near you know if you get hurt.
