Accelerate Yokohama's circular economy

What is Circular Yokohama?

Circular Yokohama is a platform to accelerate the circular economy in the city of Yokohama. We post the latest news regarding Yokohama’s circular economy, create a “circular map” that lists circular projects around the city, and develop a database for each project. On this platform, you can also find our local circular economy tours and experiences you can join. We closely work with the city, local SMEs, and NPOs under a comprehensive partnership agreement to promote the circular economy in the city.
