Introduction: Learning from Edo Japan’s Circular Economy

ROMAN KRZNARIC: Imagine you’re standing on the old wooden Nihonbashi Bridge in the ancient Japanese city of Edo, now known as Tokyo. It’s around 1750 in the era of the Tokugawa shoguns. People are chatting, labourers are pushing cartloads of rice, seafood traders are rushing across to the fish market. Now Edo wasn’t just remarkable for being a huge city of over a million people, far larger than London or Paris at the time. It also operated what we would today call a circular economy, where almost everything was reused, repaired, repurposed or recycled.

Japan’s policy of not trading with the outside world led to shortages of precious resources like wood and cotton. So a tradition of patchwork developed, known as boro, meaning tattered rags, where fragments of old cloth were sewn together into garments that were then passed on down the generations, just like the one I’m wearing, which is over 100 years old. A kimono might be used until the cloth began to wear out, then turned into pyjamas, then cut up into nappies, then used as cleaning cloth and finally burnt as fuel.

Edo had over a thousand circular businesses, from collecting candle wax strippings to be remoulded, to down-and-out samurai repairing old umbrellas. Traders even paid for human waste, which was then sold as agricultural fertiliser. Strict timber rationing rules were also introduced to restore the nation’s depleted old-growth forests. This was one of the world’s first large-scale examples of a low-waste, low-carbon ecological civilization.

Edo Japan wasn’t a utopia, having feudal and patriarchal inequalities.
