Introduction
Since it first launched in 2005, the Greenroom Festival has evolved into one of Japan’s most beloved cultural events. More than just a music and art festival, it’s a celebration rooted in surf culture and environmental awareness. As the 20th anniversary approaches in May 2025, excitement is building for what promises to be the most dynamic edition yet. The Greenroom Festival is not just a local phenomenon anymore—it has inspired movements around the world and continues to push boundaries every year.
How It All Began
The Greenroom Festival was born in Yokohama, Japan, with a mission to blend art, music, and surf culture under a unifying cause: ocean preservation. The word “greenroom” refers to the inside of a wave’s barrel—a sacred space for surfers. That imagery perfectly represents the festival’s atmosphere, where natural beauty and artistic creativity collide.
In its early years, the event was modest in size, attracting mostly local fans of surfing, independent music, and beach art. However, as awareness of environmental issues grew, so did the event. Over time, it expanded its reach and began attracting a broader audience while remaining deeply connected to its environmental mission: “Save The Beach, Save The Ocean.”
What Makes the Greenroom Festival Unique
Unlike many festivals focused solely on music, Greenroom sets itself apart by integrating environmental activism directly into the experience. The festival features eco-friendly art installations, photo exhibitions, film screenings, and panels that address issues like climate change and marine pollution. Vendors and food stalls are also encouraged to operate sustainably, using biodegradable materials and reducing plastic waste.
This holistic approach has made the Greenroom Festival more than just a weekend event—it’s a platform for raising awareness and sparking change, all while providing great entertainment.
The Big 20th Anniversary in 2025
The 2025 edition of the Greenroom Festival will take place from May 23 to 25 at Yokohama’s iconic Red Brick Warehouse. This location has long been the festival’s home and offers a picturesque view of the harbor, creating the perfect backdrop for live music and community gatherings.
For its 20th anniversary, the festival is expanding to three full days—an exciting first. The lineup already includes world-class acts such as Jacob Collier and Kamasi Washington, signaling a strong global focus while still supporting local talent. Organizers have hinted that this year will also include new features and surprises to celebrate the milestone year.

Greenroom’s International Influence
While the festival began in Japan, the Greenroom concept has inspired similar events overseas. The fusion of surf lifestyle, music, and ecological values has resonated with global audiences, leading to offshoot events and partnerships in countries with strong surf and environmental communities.
Japan’s version remains the flagship event, setting the standard for how a festival can celebrate both the arts and the Earth. It’s not uncommon for attendees to travel from abroad just to be part of the Greenroom Festival in Yokohama.
A Community with a Cause
At its heart, the Greenroom Festival is about building a conscious community. Through interactive exhibits, live mural painting, and educational booths, festival-goers are encouraged to think about the choices they make and how those choices impact the environment. Local NPOs and global eco-brands often partner with the event to spread their message and gather support.
The festival has also helped raise funds and awareness for beach cleanups and marine conservation projects across Japan. It’s a reminder that even a day of fun and music can serve a greater purpose when the right intentions are in place.
What’s Next for Greenroom?
Looking beyond 2025, it’s clear that the Greenroom Festival will continue to play a vital role in Japan’s cultural and environmental movements. As younger generations become more engaged in sustainability and as awareness around climate change continues to grow, events like Greenroom provide a blueprint for how entertainment and activism can work hand in hand.
The combination of a relaxed, beach-inspired atmosphere with world-class performances and a strong eco-message ensures that the Greenroom Festival will remain relevant—and necessary—for years to come.
