Music Festivals in May [2026]: Outdoor Festivals and Events Summary

“Green Room” is a surfing term referring to the hollow, tube-like part of a wave that surfers ride through. This event, named after that term, is held under the concept of “protecting our vanishing beaches.” Through music and art, it aims to share surf and marine culture and express a desire to protect the beach. It also sounds great to relax and enjoy music at a seaside venue.

Rainbow’s End is an outdoor acoustic festival that used to take place at the Maruyama Park Outdoor Music Hall, right next to Gion, where you can savor the essence of Kyoto. In 2026, it will move to Nantan City and be held as a camping festival. It will likely be a rare opportunity to hear acoustic performances by artists who usually play live with full band setups.

Hoshioto is held in Okayama Prefecture. Taking place in the nature-rich city of Ibara, Okayama, as the event title suggests, once night falls you can enjoy a collaboration of beautiful starry skies and music. At hoshioto in 2016, it’s said that a very beautiful starry sky was visible during Sawagi’s headlining set. We’re praying for good weather again this year!

This is a music event planned and run by local band members to energize Kagawa Prefecture. Since its start in 2018, it has been held with support from local music lovers, using venues like live houses, shopping arcades, and even rented udon shops. As a free-admission event, it has continued to grow in popularity and attendance. There are also exclusive items available only through crowdfunding, so why not take part and help boost Kagawa’s music scene?

In our “Free Music Festival,” the word “free” embodies three meanings: free of charge, freedom, and freedom from various boundaries. It’s a festival where artists of diverse genres perform, offering enjoyment across generations and opportunities for new discoveries.
