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 rock festival started in the spring of 2023 to energize the North Kanto area. It brings together must-see and supportive artists who fire up the crowd with their performances—an essential part of any music festival. It’s a new-style event that rotates its venue each year among Ibaraki, Tochigi, and Gunma prefectures, and we’re also focusing on the market aspect so it can become an event cherished by the local community. As with any great fest, you can indulge in popular local foods and take part in workshops—unique experiences you can only enjoy here.
