June Music Festivals [2025–2026] Outdoor Festivals & Events Summary

This is a music event organized by the female-vocal band IRabBits, bringing together girl bands. It was held from 2009 to 2014, and will be revived in 2023. With more artists now active in girl bands than before, it’s rare to get a chance to see so many high-energy bands all at once. There will also be collaboration projects with female idol groups, so it’s shaping up to be a hot event. I’m excited to see what kind of performances they’ll deliver.

Rockin’ Radio!, an FM802 event, is held every spring at Osaka Castle Outdoor Music Hall. It’s organized as a “Kansai-born omnibus rock event” that brings together the hottest rock bands of the moment. It’s a recommended event where you can enjoy live performances at a relatively affordable price.

We live our daily lives alongside song. In any scene, music is an essential presence that enlivens the moment as a supporting role. However, it’s rare for song to take center stage! This is a festival conceived for that splendid supporting actor—the festival for songs!
