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.
