48th Setagaya Tamagawa Fireworks Festival — Multicolored star mines dye the night sky
One half of Tokyo's twin-bank Tama River fireworks evening: Setagaya and Kawasaki launch simultaneously from opposite shores on October 3, 2026, so every burst you watch is doubled across the water. Setagaya's 48th edition carries the theme 'Sho—A New Flight Across the Night Sky,' sending up about 6,000 shells in a single hour from 18:00 at the riverside green upstream of Futago Bridge. Around 270,000 spectators come for what is, logistically, one of the easiest major fireworks shows to reach by train in Tokyo.
Viewing centers on the ward athletic field upstream of Futago Bridge, about a 15-minute walk from Futagotamagawa Station—expect serious crowd pressure on the day. The single-hour format (18:00–19:00) makes post-show dinner plans realistic. Stage events run from 15:00. Paid seats start at 6,500 yen, with pair seats and large sheet sections above that, sold after a ward-resident priority window via Rakuten Ticket and other channels. There is no event parking, and traffic-control timings differ between the Setagaya and Kawasaki banks, so crossing the river on foot mid-event is not dependable. If storms hit, the show is cancelled outright with no reserve date. Stage events from 15:00 fill the waiting hours, and the ward publishes its own notices on traffic regulations and bus diversions for the day—worth reading before you set out.
