Connecting people, nature, cities, and communities"City Green"
Bring green to the city.Make ethical living a culture.
About
City Green creates new connections among people, nature, cities, and local communities.
We bring people, communities, businesses, and regions together so that each can build on the activities and resources of the others.
Under the idea of making ethical living a culture, we design welcoming ways to take social action through festivals, nature experiences, community gatherings, local projects, and collaboration with businesses.
“City” means more than an urban place: it also means the culture and systems people create. “Green” reaches beyond nature to include circularity, diversity, and coexistence. We want these different activities to grow together.
Fes → Relationship → Network
From one encounter to the next action.
A festival can be the beginning. By meeting, sharing ideas, and planning together, people and organizations build relationships that lead to new work with businesses and local communities.

Bring green to the city. Turn ethical action into a culture people want to join.
I want environmental action to be driven by curiosity and excitement, rather than obligation. Experiences that move us can bring people together and inspire lasting action.
City Green connects people and nature, cities and regions. Starting from Tokyo, we aim for a future where economic activity and care for the planet can grow together.
