The legendary paint marker brand teams up with Juddy Roller and Wall Share to celebrate the roots of street art across two continents.
October 2025 — POSCA, the iconic paint marker brand that has coloured the history of graffiti and street culture since the 1980s, is launching an ambitious cross-continental art project that brings together Japan and Australia through muralism.
In collaboration with Juddy Roller (Melbourne) and WALL SHARE Inc. (Osaka), POSCA presents the Mural Exchange Program, a creative initiative running from October 16 to November 1, 2025, that invites two renowned artists — Adnate from Australia and HIROTTON from Japan — to swap cities and create large-scale works inspired by the shared spirit of creative freedom.
Osaka × Melbourne — Two cities, one creative dialogue
The first mural will be produced in Osaka’s Konohana district between October 16 and 24, an area known internationally as Mural Town Konohana thanks to WALL SHARE’s ongoing program that has already hosted over 30 large-scale murals from artists around the world.
The second wall will rise in Melbourne’s Collingwood neighbourhood from October 25 to November 1, with local powerhouse Juddy Roller handling wall production, logistics, and on-the-ground support.
Through these two activations, POSCA aims to bridge cultural and creative communities, using mural art as a universal language to communicate its founding philosophy: the joy of creative expression.
Colour as connection
Since the 1980s, POSCA markers have been a staple in the hands of graffiti writers, illustrators, and muralists around the world. Now, four decades later, the brand revisits its roots — moving beyond paper and canvas to reclaim the wall as a space for dialogue and exchange.
“Mural art embodies what POSCA has always stood for — creativity that exists in public space and belongs to everyone,” says the project team.
By linking Osaka and Melbourne, two cities with strong street art cultures, the POSCA Mural Exchange Program reaffirms how art can transcend geography and bring people together through colour and collaboration.
The artists
Adnate (Australia) is known globally for his monumental portrait murals, often focused on Indigenous representation and human emotion. His style merges Renaissance-inspired chiaroscuro with the raw immediacy of spray paint, resulting in works that command both presence and empathy.
HIROTTON (Japan) brings a punk-infused aesthetic shaped by his years in London’s underground art scene. Blending illustration, graphic design, and skate culture, his visual language is both rebellious and deeply personal — a perfect match for the project’s ethos.
More than collaboration
Produced with the support of Mitsubishi Pencil Australia Pty Ltd., Juddy Roller, and WALL SHARE Inc., the project also includes film documentation by Shoyo Miyao (ZONVOX Inc.), capturing the full creative process in both cities.
No competitions, no commissions — just two artists, two walls, and one shared mission: to paint a story of cultural connection across borders.
