Yokohama Green Expo Aims to Blend Edo-Era Circularity with Modern Sustainability
By Drooid · · How we work
Overview of the Event
The Yokohama Green Expo will open on March 19 and run for six months, covering roughly 100 hectares on the former U.S. military communications site. Organizers plan to plant ten million specimens, including 600 cherry trees timed to bloom at the opening.
Historical Inspiration and Circular Economy
A central pavilion will focus on the Edo Period (1603-1867), a time described by scholars as a “golden period” for circular practices. Experts note that Edo residents routinely repaired clothing, repurposed paper through “kamikuzu-kai” waste-paper buyers, and used strict timber regulations to curb deforestation. Organizers argue that these historic habits can inform contemporary disaster mitigation, citing Edo-era flood-control methods that combined public cherry-blossom viewing with soil compaction on dikes.
Key Organizers and Vision
Kazuko Ishigaki, executive director of the expo’s public-relations department and former UN-Habitat regional director for Asia-Pacific, leads the initiative. She emphasizes reviving Edo-era mindsets to shape modern product design, echoing philosopher Roman Krznaric’s call for smartphones built with modular, recyclable components. Ishigaki also highlights the reuse of timber from the Sou Fujimoto-designed Grand Ring of the Osaka Expo, describing it as a tangible symbol of a “zero-waste society.”
Visitor Goals and Practical Measures
The expo targets 10 million visitors and hopes to sell 5 million advance tickets. To avoid the extreme-heat challenges that plagued the Osaka Expo, planners will provide extensive tree cover, mist fans, cooling stations, and child-friendly shaded areas. Ishigaki warns that some people may view the event merely as a flower show, stressing that it is a nationally authorized expo intended to reshape public perception of the human-nature relationship.

*Quotes from Kazuko Ishigaki*
- “One of the major pavilions — a horticulture pavilion — will be focused on the Edo Period to showcase or highlight how the people of the Edo Period lived in harmony with nature.”
- “Maybe some people misunderstand, (thinking) this is just an event to enjoy flowers. This is a national event — this is a formally authorized expo.”
- “They might think this is not related to their life, but that’s not true.”
