Uncovering Urban Secrets: Zenigame Sewage Research Presentation

The YAU Art Urbanism Project presents the 'Zenigame Sewage Research Presentation Vol.1: Holes', a unique exhibition running from March 13 to March 29, 2026, at YAU CENTER, located within the Zenigame Place in Chiyoda, Tokyo. This exhibition showcases the outputs of a collaborative research initiative focusing on the city’s underground sewage infrastructure.

Urban sewage systems, crucial for daily life yet often overlooked, manage the water we consume—the average individual uses approximately 220 liters daily, most of which is treated and released back into rivers and seas within 24 hours. The Zenigame Sewage Research project sees a diverse group of researchers, including artists, musicians, editors, and architects, collaborating with the Tokyo Metropolitan Bureau of Sewerage to explore the interconnections between urban life and sewage systems. This ongoing project, continuing until 2027, invites attendees to observe and engage with the complex relationship between urban environments and their hidden infrastructures.

Exhibits: Highlights of the Show

Observing Microbial Life Through Art

The centerpiece of the exhibition is a stunning work by artist Tomoya Ishibashi, who combines his biological background with artistic exploration. His installation features a microscope created from litter collected from the Shibuya River, a body of water that receives treated sewage. Visitors can observe key microbial communities, specifically activated sludge—critical players in sewage treatment—through the microscope. Additionally, images of these microorganisms will be projected onto actual manholes used in Tokyo, reinforcing the connection between art and the unseen forces that maintain urban water systems.

Ishibashi’s work serves as a poignant reminder of the synergy between human engineering and nature's ecosystems, highlighting how these microorganisms sustain water purification processes within engineered urban infrastructures. As he notes, "The sewage treatment process represents a highly nuanced network of technologies designed around the dynamics of nature, embodied in the age-old presence of microorganisms."

Immersive Research Experience

Another component of the exhibition features documentation of the research team's fieldwork, showcasing records from visits to various sewage treatment facilities, including the Ariake Water Reclamation Center and the Zenibikin Town Pump Station. This allows visitors to engage in the investigative journey that the research team undertook, with exhibits displaying observational notes and inquiries made during their explorations of urban sewage systems.

The research team comprises a cross-disciplinary group, including publishers, artists, photographers, musicians, spatial designers, and urban researchers, each bringing their unique perspective to the analysis of urban infrastructure.

An Artistic Project on Urban Research

Ultimately, the Zenigame Sewage Research initiative aims to bridge art and research to illuminate the structures that underpin urban life. The sewage system serves as a metaphor for the relationship between human activity and nature's purification capabilities. While human infrastructure, which emerged as a response to pollutive practices, is deeply intertwined with organisms that existed long before humanity, this exhibition intends to recast our understanding of urban foundations through an artistic lens.

Venue Analysis: YAU CENTER Zenigame

Located above the Zenibikin Town Pump Station—which plays a critical role in pumping wastewater from areas like Marunouchi—YAU CENTER serves as a hub for artistic innovation and urban research planning. Since its inauguration in 2025, it has facilitated artistic endeavors in conjunction with urban realities, highlighting the creative processes of artists involved in community-centered projects.

The exhibition is free to the public, driven by the vision of YAU to connect art with urban environmental issues, showcasing artworks that urge conversations about our interactions with hidden infrastructures.

Related Events

As part of this initiative, on March 20, a talk and field-walk event entitled 'Exploring the Invisible Networks of Sewage and Rivers' will be held. Renowned researcher Akira Honda will join Tomoya Ishibashi for discussions on the relationship between rivers, water, and humanity, followed by a guided exploration of urban streams.
