If they go ahead, 2021 will be the 55th edition of the annual Katsushika Noryo Fireworks Festival (the date is uncertain due to COVID and the Olympics). An impressive 13,000 fireworks will go off and almost 800,000 spectators are set to watch them. In the event of rain, the event will be postponed to the following day.
The fireworks will hopefully be happening at the Shibamata baseball ground near the Edogawa River—just 10 minutes from Keisei Shibamata Station.
Please note that due to the 2020 Olympics (scheduled for July/August 2021), the event date may be moved from its normally scheduled date in late July to possibly some time in October.Organizers may cancel events, alter schedules, or change admission requirements without notice. Always check official sites before heading to an event.
