Koto Fireworks Festival

With around 6,000 fireworks shells, Koto Ward’s annual hanabi festival may not be as large as some of Tokyo’s other fireworks events, but its scenic riverside setting more than makes up for it. Head to Arakawa Sunamachi Riverside Park for a spectacular show launched just 150m from the viewing area. As the event falls on a public holiday this year, expect bigger crowds than usual.

Seating reservations are required to access the venue. While prices are yet to be announced for 2026, ticket usually start at ¥5,000 per seat. More details are to be announced on July 1 via the official city website.
