Osaka Festival Calendar [2026]: Music Festivals and Outdoor Events Summary

It’s a free outdoor rock festival held in Takatsuki, a city also famous for its jazz festival. It’s a large event that draws around ten thousand people every year, but the goal is 300,000! It’s an exciting event with the potential to grow that big.

The Hirakata-juku Jazz Street is an initiative led by a citizens’ group and has grown to attract as many as 10,000 attendees. Marking the 70th anniversary of the city’s incorporation this year, under the slogan “Hirakata City: 70 Years of Dreams, Soaring Even Higher,” they are taking a flexible approach—without limiting themselves to jazz—to energize the city.

RUSH BALL is a summer tradition of Osaka’s rock scene that has been held since 1999. The venue, Izumiotsu Phoenix, faces the sea, where you can feel the ocean breeze, and its sprawling lawns make for an incredibly comfortable festival experience. The lineup never disappoints—expect everything from staple festival veterans to promising young newcomers!
