Sumida River Fireworks Festival

The Sumida River Fireworks Festival (Sumidagawa Hanabi Taikai) is Tokyo’s oldest and largest hanabi display, dating in its original form to 1733 when the Tokugawa shogunate staged fireworks on the river to mourn victims of a famine and epidemic. Today the event draws close to 1 million spectators along the Sumida River banks and surrounding streets of Asakusa and Mukojima, with approximately 20,000 shells fired from two separate launch sites over roughly 90 minutes.

The Two Launch Sites

The festival divides its display between two sites (kaijo) positioned along a roughly 2-kilometre stretch of the Sumida River between Sakurabashi and Kototoibashi bridges. Site 1, the larger of the two, fires from near Umayabashi bridge and can be seen from the Asakusa and Taito-ku bank. Site 2 fires from near Kototoibashi and is best viewed from the Sumida-ku (Mukojima) side of the river.

The two sites alternate and coordinate their shells to produce synchronised bursts visible from much of the river corridor. The displays include standard chrysanthemum shells alongside specialist hanabi in star, peony, and willow formations. Competition teams of professional fireworks makers (hanabi-shi) enter their work in judged sections of the evening.

Where to Watch

The riverside park between Umayabashi and Kototoibashi on the Taito-ku (Asakusa) side is the primary free viewing zone. Entry to this ticketed park section (approximately 700-2,000 yen as of 2026, purchased in advance through convenience store terminals or online) gives a reserved seat on the bank with clear sight lines to Site 1. General free viewing is possible from the bridge approaches and side streets of Asakusa, though sightlines from these areas vary considerably based on exactly where you stand.

The Mukojima side of the river, reached from Higashi-Mukojima Station (Tobu Skytree Line), is often less crowded than the Asakusa bank and provides good views of both sites from a distance. Rooftop restaurants and bars in the Asakusa area offer premium views; many sell dinner or drinks packages for the evening that book out weeks in advance.

Chartered yakatabune (traditional flat-bottomed pleasure boats) cruise the river during the display and provide close-range views from the water. Boats seat 10-30 people and are typically booked months ahead through operators on the Sumida; prices are significant but the experience of watching hanabi from the river itself is unlike anything possible from the bank.

Practical Notes

The festival takes place on the last Saturday of July (check the official date for 2026 as it has occasionally shifted due to weather). The display runs from approximately 7:05pm to 8:30pm. Crowds arrive from early afternoon - positions along the bank fill by 3-4pm for prime spots.

The closest stations are Asakusa (Tokyo Metro Ginza Line, Tobu Skytree Line) and Asakusa (Asakusa Line). All stations in the area are heavily congested after the display ends; many locals stay near the riverside for an hour after the finale to allow the crush to ease. Wearing a yukata (summer cotton kimono) is traditional at hanabi festivals - rental shops in Asakusa offer sets from approximately 4,000-6,000 yen for the day. Tokyo in late July is typically 33-35°C with high humidity; carry water.
