GREENROOM FESTIVALSat 5/23–Sun 5/24, Kanagawa Prefecture

“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.
