What this is
GREENROOM FESTIVAL is Japan's premier beach and surf culture music festival, held annually at the iconic Yokohama Red Brick Warehouse waterfront complex. Now in its long-running history, the festival blends live music with surf, skate, and ocean lifestyle culture, making it unique among Japanese music events. The 2026 edition runs across two days — Saturday and Sunday, May 23–24 — against the stunning backdrop of Yokohama Bay. It is one of the most visually distinctive outdoor festivals in Japan, attracting both music fans and those drawn to the coastal creative lifestyle scene.
Who should go
This festival is ideal for music lovers, surf and beach culture enthusiasts, and anyone who enjoys a stylish outdoor event with a relaxed coastal vibe. The atmosphere tends to be fashionable and laid-back, attracting a creative, internationally-minded crowd. Families, couples, and solo festival-goers all fit in comfortably here. Arrive early on your chosen day to explore the vendor area and secure a good spot before the main acts take the stage.
Good to know
Tickets for GREENROOM FESTIVAL are typically available through eplus.jp and pia.jp, both of which accept foreign credit cards; convenience store pickup at Lawson is the easiest option for visitors staying in Japan. The event takes place on the open waterfront plaza surrounding the Yokohama Red Brick Warehouse, so it is an outdoor standing/roaming festival — comfortable shoes and weather-appropriate clothing are essential. The bay-facing location means wind can pick up in the late afternoon, so a light jacket is recommended even in May. Multiple stages and a large lifestyle market area mean you can easily spend the full day on-site; doors typically open mid-morning. Photo policies vary by artist, so check stage-specific rules on the day.
