Aichi's Famous Festival
The Toyota City Oiden Festival

The Toyota Oiden Festival is a famous summer event held every July for two days in Toyota City, Aichi Prefecture. Centered around a mass dance and a large-scale fireworks display, it’s considered one of Japan’s quintessential summer traditions.
On the first day, the “Oiden Mass Dance” takes place, a cheerful festival open to everyone. Groups called odori-ren (“dance teams”) dance freely in their own costumes. Each group can consist of company employees, groups of friends, or anyone with a shared interest, and their dance styles are just as varied. Participants dance to the festival’s signature “Oiden” song in whatever way they like. At the end, the audience votes to decide the grand prize-winning odori-ren, ensuring plenty of excitement.
The second day features a fireworks display—the grand finale of the Toyota Oiden Festival—which is the largest of its kind in the Tokai region. Every year, around 360,000 spectators come to watch. Renowned pyrotechnicians from across Japan participate, launching about 13,000 fireworks over roughly 100 minutes. The performances are spectacular, with highlights such as tezutsu hanabi (hand-held fireworks) and the “Niagara Falls” display, both of which captivate audiences annually. The venue is just a 1–3 minute walk from the nearest train station, making access easy.

Marine Day Nagoya Port Festival

The Nagoya Minato Festival on Marine Day is a long-standing traditional event held at Nagoya Port in Aichi Prefecture, attracting some 300,000 visitors each year.
The festival is free to attend. From daytime through evening, visitors can enjoy performances of kagura (Shinto music and dance) and Japanese taiko drums presented by Minato Ward, view festival floats (dashi), and watch a mass dance by local residents. The festival concludes with a beautiful fireworks display.
During this grand finale, about 3,000 fireworks, including rapid-fire “starmine” sequences and massive shells are launched over roughly 100 minutes. Particularly striking are the one-shaku shells, which open into giant 30-meter blooms that captivate spectators. Another highlight is the “Memorial Fireworks”, where messages submitted in advance by individuals or companies are announced and launched along with the fireworks. Submissions are usually accepted until mid-May, so it’s worth considering sending in a message to see it celebrated in the sky on the day of the festival.
Numerous food stalls also line the festival grounds, making it easy to enjoy drinks and snacks while watching the fireworks. With a subway station located nearby, access to the venue is simple and convenient.
