"Lucky Seven” Jet Balloon Release - Japanese Baseball’s 7th Inning Stretch

In the 7th inning of Nippon Professional Baseball (NPB) games, fans sing their team’s fight song and then release “jet balloons” into the air. Don’t worry though - in typical Japanese fashion, the fans diligently clean up after themselves. Here are some photos and videos from the Fukuoka PayPay Dome (Fukuoka SoftBank Hawks), MAZDA Zoom-Zoom Stadium (Hiroshima Toyo Carp), the Kyocera Dome Osaka (Orix Buffaloes), the Nagoya Dome (Chunichi Dragons), and Koshien Stadium (Hanshin Tigers).
