The Itabashi Fireworks Festival is always a good show. Roughly 12,000 fireworks are expected to go off this year—and there should be some colorful character and flower shapes in the mix. The event goes on for an hour and 30 minutes. There are reserved seats and general sitting areas at the venue. If you don’t feel like dealing with the crowds, just invite yourself over to a friend who lives near Tobu-Nerima Station and watch from their place.
The nearest station is Nishidai on the Toei Mita Line.
Please note this event is usually held in August, but was moved due to the Olympics and then cancelled due to Covid-19. It is not yet known which month it will be scheduled for in 2021, if any.
