700,000 Flowers Transform Brussels Into Japanese Masterpiece

Brussels just turned one of Europe's most beautiful squares into a living work of art, and the result is stopping tourists in their tracks.

The Grand-Place, a UNESCO World Heritage site, now features a massive flower carpet stretching 70 meters long and 24 meters wide. Japanese artist Hiro Sugiyama reimagined Katsushika Hokusai's famous "Great Wave off Kanagawa" using more than 700,000 flowers, mostly Belgian dahlias.

Sugiyama spent eight months designing the composition, carefully working within a 16-color palette due to time constraints. "To be honest, at the beginning, I was pretty nervous about the limited colors," he said. "But once I came here and saw the design laid out, I realized I didn't need to worry because it looks beautiful already."

On Thursday, over 100 volunteers worked together for six hours to bring the vision to life. Even Japan's Ambassador to Belgium, Takeshi Osuga, rolled up his sleeves to help arrange the flowers. "A lot of Japanese sponsors contributed to this event and I wanted to contribute by laying out the flowers," he said.

The 2026 carpet marks a special milestone: 160 years of diplomatic ties between Belgium and Japan. It's also the second collaboration between the nations on this beloved tradition, following their first partnership in 2016.

Richard Poncin from the Brussels Flower Carpet Organisation says the event goes far beyond creating pretty pictures. "Culture events show people that we can work together, we can do interesting things together," he explained.

The Ripple Effect

This biennial tradition, which started in 1971, brings together communities in beautiful ways. Volunteers from different backgrounds spend days preparing the full-size canvas, calculating flower quantities, and carefully placing each bloom. The result draws visitors from around the world to witness what international cooperation can create.

Visitors can walk around the carpet or view it from the Town Hall balcony for an aerial perspective of the wave's dramatic curves and vibrant colors. While online tickets sold out quickly, walk-up tickets remain available at the venue.

The display runs through August 16, giving thousands of people just four days to experience this temporary treasure before the flowers are removed and the historic cobblestones return.

Sometimes the most powerful statements about unity come not from words, but from 700,000 flowers arranged with care by hands working toward a shared vision.
