Summer in Japan is famously hot and humid. Everywhere you go, you’ll find kakigori shops (shaved ice) offering sweet relief, people gracefully fanning themselves, and many wearing colorful yukata, the light cotton kimonos perfect for summer festivals. During these months, cities across Japan come alive with traditional festivals and outdoor events for families and friends. Most of these celebrations culminate in dazzling fireworks displays, known as hanabi —a beloved summer tradition that has enchanted the Japanese for centuries.
How This Fireworks Tradition Started
The story of hanabi in Japan goes back to the Edo Period (1603–1868). While fireworks in the West are often reserved for special occasions like New Year’s Eve or national holidays, in Japan, hanabi became a seasonal spectacle enjoyed all throughout summer, lighting up the night skies from June to August.
It is believed that fireworks were first introduced to Japan from China via Korean traders and missionaries in the early 17th century. Originally, they were used in religious ceremonies designed to ward off evil spirits and pray for good harvests. Over time, the entertainment aspect grew, and fireworks became a way to unite communities and celebrate life amid the sweltering summer heat.
One of the most famous early hanabi events was hosted by the Tokugawa shogunate in Edo (modern Tokyo), where large-scale fireworks competitions were held on the Sumida River, with a long history dating back to 1733. These events not only showcased the dazzling colors and patterns of the fireworks but also activated rivalries among the skilled pyrotechnicians—a tradition that continues today in the form of annual fireworks contests.
What to Bring to the Fireworks Festival
Fireworks festivals usually take place in parks or along riverbanks, where grassy areas provide the perfect spot to sit and enjoy the show. It’s a good idea to bring a large picnic cloth to sit on or small foldable chairs for comfort.
Don’t forget plenty of cold beverages like water and juice to stay hydrated during the warm evening. While many festivals feature yatai (food stalls) selling delicious Japanese snacks—from yakitori to takoyaki—these can have long lines. To avoid missing the fireworks, consider bringing your own easy-to-eat food like onigiri (rice balls) or sandwiches.
Check Your Prefecture’s Fireworks Calendar
Although Tokyo, Osaka, and other major cities host some of the biggest and most spectacular fireworks displays, every prefecture in Japan holds its own hanabi festival during summer, usually between late July and August.
Some of the most famous include the Sumida River Fireworks Festival in Tokyo—that will be held this year on Saturday, July 26th— the Nagasaki Lantern Festival, and the Naniwa Yodogawa Fireworks Festival in Osaka. Each has its own unique atmosphere and style, offering visitors an authentic glimpse into Japanese summer culture. Check here for further information.
