Tokyo police arrested a yakuza member for attending a baseball game, reminding everyone of the 2003 ban. This rule extends to the entire Tokyo Dome venue, potentially affecting idol concerts as well.

Japanese baseball stadiums have banned yakuza members since 2003. A recent arrest in Tokyo highlights the seriousness of this rule: a yakuza member was caught attending a Yomiuri Giants game at Tokyo Dome and faced legal repercussions.

Tokyo Dome's ban extends beyond baseball games, potentially affecting other events like idol concerts. The stadium's website explicitly prohibits entry to anyone associated with organized crime, ensuring a safe and family-friendly environment.

Travelers should be aware that venues in Japan take these rules seriously. While this may not directly impact most visitors, it's a reminder of the strict regulations and cultural norms regarding organized crime in Japan.
