The 49th Sumida River Fireworks Festival - Night view woven by Skytree, fireworks, and yakatabune boats
Held on 25 July along the Sumida River in Sumida Ward, Tokyo, this is the Kanto region's most storied fireworks event. Its lineage traces back to the 'Ryogoku Kawabiraki' river festival of 1733, and after several interruptions over the centuries it was relaunched under its current name in 1978. Around 20,000 shells rise from two stretches of the river — downstream of Sakura-bashi to upstream of Kototoi-bashi (first venue) and downstream of Komagata-bashi to upstream of Umaya-bashi (second venue) — and the 2025 edition drew an estimated 930,000 visitors. There is no parking, so come by public transport; the official website has details of paid seating.
Sumidagawa Hanabi Taikai carries on the fireworks tradition of Edo-period Ryogoku: the display's origins lie in the 'Ryogoku Kawabiraki' festival of 1733, and after repeated interruptions through its long history it was revived in 1978 under its present name, reaching its 49th edition in 2026. Widely regarded as the most storied fireworks event in the Kanto region, it drew about 930,000 visitors in 2025. Around 20,000 shells are fired between 19:00 and 20:30. Two classic shell types define the show: 'warimono', which open into a broad, near-perfect sphere, and 'pokamono', which split apart mid-air and scatter burning stars from within. At the first venue, pyrotechnists with ties to the Ryogoku fireworks tradition and past contest winners face off in a judged fireworks competition. With crowds on this scale, aim to arrive two to three hours before the start; free viewing spots fill from early afternoon and the riverside walkways stay busy all evening. There is no parking at the venue — the first venue is a 15-minute walk from Asakusa Station, the second a 5-minute walk from Asakusa or Kuramae — so plan on trains and subways. Paid seats are best bought in advance; see the official website for details.
