The Adachi Fireworks Festival marks the beginning of the summer fireworks season in Tokyo. This large-scale event attracts around 700,000 visitors each year, making it popular not only among locals but also international travelers. In 2025, it will be held in May—two months earlier than usual—offering a more pleasant viewing experience thanks to the milder weather. This year’s event is even more special, celebrating the 400th anniversary of Senju-juku’s founding with commemorative firework displays.
1. What Is the Adachi Fireworks Festival?
The Adachi Fireworks Festival is a major fireworks event organized by Adachi City along the banks of the Arakawa River. Utilizing the wide-open riverside setting, the show captivates spectators with large-scale displays. While the largest shells used are 4-shaku balls (12 cm in diameter), the frequent use of rapid-fire “starmine” fireworks fills the entire sky with dazzling density and impact.

3. History of the Festival
The origins of the Adachi Fireworks trace back to the Meiji era, when fireworks were launched along the Arakawa River. It was revived in 1979 (Showa 54) in its current form and has since become a cherished summer tradition. The 2025 event marks the 47th edition.
This year also celebrates the 400th anniversary of Senju-juku, once the first post town on the historic Nikko Kaido. It flourished in the Edo period as a vital hub for trade and travelers. The festival offers a unique opportunity to appreciate this rich cultural heritage through fireworks.
- Nikko Kaido: One of the five major routes established in the Edo period, connecting Edo (modern-day Tokyo) to Nikko Toshogu Shrine. It was used by shoguns on pilgrimage and supported many bustling post towns.
- Post Towns: Settlements built along major roads in the Edo period to accommodate travelers and facilitate trade, often evolving into cultural and commercial centers.
