How Japan saved its biggest city from collapse – Roman Krznaric

Dig into Edo, Japan’s circular economy, and how it helped transform the city into a thriving ecological and cultural center.

400 years ago, Edo was on the verge of ecological collapse. Years of intense logging had led to massive deforestation and the city faced timber shortages, severe erosion, and frequent flooding. But over just a few decades, Edo became one of the most sustainable and efficient cities in history. So, how did this come about? Roman Krznaric explores Edo’s transformation into a circular economy.

  1. Well, Edo period’s international trades were optimized, not restricted. Japan imported so much goods from China, Korea, Ryukyu, Ezo (Hokkaido), Thailand, Indonesia (through Chinese, Dutch, and Korean traders) throughout Edo period. Also exported to the exact countries and western countries through Dutch Eastern Indian company in Dejima, Nagasaki. Edo and the previous governments were super furious about Spanish and Portuguese missionaries/traders who sold Japanese citizens as slaves to South America and Europe. Every Japanese leaders knew what Europeans were doing in Americas and other Asian countries. They were the sharpest leaders in the world at the time (survived over 100 years of wars).

  2. For the wages of sin is death but the free gift of God is eternal life through Christ Jesus our lord. We all sin and the consequence of sin is separation from God but God offers salvation through his son Jesus Christ and all we have to do is believe in him, recieve him and follow him. (Copy and paste to share the gospel)

  3. A very creative way of romanticizing misery. The vast majority of Japanese during that period lived in utter misery, not simply poverty. Recycling was born out of necessity, not out of some deep philosophical wisdom.
    Yes, much of the world was poor as well, but commerce and international relations were gradually changing how countries lived, a process that never truly ends.
    Of course, there is value in being creative with what can be reused, but we should keep our perspective clear. Our current technology cannot, and will not, survive by sewing rags together. Many SciFi movies imply some marriage between highly advanced technologies and a rural, quaint life: those are just fantasies.

  4. Close analysis of this video shows that the many practices presented as cultural are in fact merely rational. The fact that these people, who by happenstance were Japanese, and/or were by happenstance Buddhist, achieved these efficiencies doesn't confirm the notion that they achieved these efficiencies BECAUSE they were Japanese and/or Buddhist and therefore not "contaminated" by the "ev|ls" of the modern, secular, rationalist, industrialized Anglophone/European so-called "Western" world. No. They achieved these efficiencies by looking at things rationally. They used the laws of physics, chemistry, energy, and motion to make life easier and more stable. Anyone anywhere in the world who employs rationality in these same ways will achieve these same results, regardless of any allegations that their "culture" is "contaminated". The people in this video should be praised for the rational foresight they chose to exercise, without praising them for some allegedly "special" way of thinking that arose from their being Japanese, Buddhist, or otherwise "superior" to allegedly wasteful consumerist countries. There are no "special" people. But there are virtuous people (such as the ones in this video) who choose to be practical rather than special.

  5. This was only a temporary solution and doesn't work long term. You need to trade with the outside world. If not, you become like North Korea.

  6. Sometimes, in this rapid world, we need to remind ourself to feel enough. This history reflects how circular economy idea is somehow a feudal idea but still relevant until nowadays.

  7. Govt's tends to be lazy, but Edo did the opposite. Yeah it had its flaws, but I believe it is what influenced Japan to become a nation that can rebuilt, solve problems instead of avoiding like most, and rely on itself. That's why I am curious to see how the Japanese solve their current problem of population decrease

  8. The "mottainai" part sounds a lot like "keikaku means plan" meme. It's just an expression that translates to "what a waste". Japanese wikipedia page of the expression indicates that claims that say it's of buddist origin are doubtful.
