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

Editor-in-Chief, RAG MUSICHane Keisuke
Editor-in-chief of RAG MUSIC. JFC-certified fact-checker. After working in a music studio and handling wedding sound, joined the RAG MUSIC editorial team in 2016. Experienced with a variety of instruments: marching band in elementary school, clarinet in junior high school wind ensemble, and drums in a band from high school onward. Drawing on my own musical activities and the experience gained through my work, I produce daily articles, including various song introductions, features on music festivals around the country, and live reports. In music, I enjoy not only rock from Japan and abroad but, lately, a wide range of J-pop as well.

In this article, we’ll introduce a wide range of music festivals held in Osaka all at once!

When it comes to music festivals in Osaka, there’s a packed lineup of events featuring popular artists from Japan and abroad—such as SUMMER SONIC, held every summer, its spin-off events, and massive indoor festivals at the end of the year.

Another hallmark of Osaka’s events is their variety: from urban-style circuit festivals that use multiple live venues, to events in Osaka Castle Park, to seaside festivals where you can see the ocean—there’s something for every taste.

Find an event that interests you and be sure to check it out in person!
