This is the big daddy of summer fireworks festivals in Tokyo. The fireworks kick off at 7:05pm and run for a full 90 minutes. This festival attracts massive crowds. Check out our guide to surviving the Sumidagawa Fireworks Festival.
For spots that afford a good view and aren’t insanely crowded, we recommend Shiori Park (600m from Minamisenju Station) or the north part of Oyokogawa Water Park near Tokyo Skytree and Honjo-Azumabashi Stations.
If there is stormy weather the event may be postponed until the following day.
