Christian Dimmer
Christian Dimmer is a Germany-born educator, author, researcher, and transition design practitioner who has been based in Tokyo for 25 years. Amidst a cascading polycrisis, the question is no longer whether cities will change — but how. As an Associate Professor of Transition Design & Urban Studies at Waseda University, he explores how urban systems, design practices, and public spaces can act as catalysts for positive socio-ecological transformation. Bridging local knowledge and global frameworks, he engages Tokyo as a dynamic testing ground for resilience, governance, and the future of urban life. What drives his research is a search for leverage points — the small, networked interventions that can tip a community's trajectory towards something more just and ecologically resilient. He's especially drawn to the politics of public space and the quiet, often contested ways urban commons take root. Recent publications include Tokyo's Perpetual Resilience Project: Between Local Knowledges and Universal Modernist Concepts (2025), Spatialising Pandemic Politics during the 2020 Tokyo Olympics (2024), and Sustainability and Adaptation in Planning: Community Resilience Against Accelerating Environmental Change (2024). Beyond thinking about the commons, Christian lives in one of Japan's first collective houses — a shared, inter-generational living experiment in which theory is tested daily against the reality of pooled space and shared life.
