Janelle Monáe has joined the lineup for GREENROOM FESTIVAL ’26, set for May 23–24 at Yokohama Red Brick Warehouse.

The genre-blurring artist will perform on May 24, marking one of the festival’s biggest international bookings in this year’s lineup.
Launched in Yokohama in 2005, GREENROOM FESTIVAL is built around the concept of “Save The Ocean,” blending music, art, and beach culture. The event has steadily expanded over the years, staging the Local Green Festival in autumn and celebrating its 20th anniversary in 2025 with a three-day edition.
Monáe joins an already strong bill featuring ELLA MAI, JON BATISTE, KREVA, Dragon Ash, and KID FRESINO, arriving as part of the festival’s fifth wave of artist announcements.
