Japan's Economic Miracle, Bubble, and Lost Decades: Lessons for China and the World

Minimizing military spending and war reparations accelerates economic reconstruction.

The US pushed for minimal reparations to avoid repeating WWI mistakes; Japan gave up military force and relied on US protection, freeing resources for economic rebuilding.

Why: Eliminating a massive expense line item allows full resource allocation to productive capacity and infrastructure.

"Japan had previously spent massively on its military, so eliminating this significant expense allowed Japan to put all of its strength and resources into reconstructing the economy."

Export-led growth requires undervalued currency and suppressed domestic consumption.

Japan kept the yen weak, making exports competitive and imports expensive, while forcing domestic households to save rather than consume.

Why: A weak currency subsidizes exports and builds foreign reserves, but at the cost of living standards and domestic demand.

"Japan keeping its currency weak made its exports more competitive in global markets, and also made imported goods more expensive in Japan."

Centralized credit rationing (window guidance) can direct industrial policy but breeds malinvestment.

Bank of Japan set loan quotas by industry, creating a 'centralized war economy system adapted to the production of consumer goods.'

Why: Quantity-based credit control overrides price signals, leading to over-investment in favored sectors and under-investment elsewhere.

"Instead of the central bank just setting the price of money, which is the interest rate, they would also decide on the quantity of credit and which businesses it would be lent to."

Sharp currency appreciation combined with ultra-low rates creates asset bubbles.

After the Plaza Accord (1985), yen soared 50%; BoJ slashed rates and raised loan quotas 15% annually, driving stocks +240% and land +245% in four years.

Why: Currency revaluation plus cheap credit channels excess liquidity into speculative assets rather than productive investment.

"The credit boom caused not only a boom in real estate, but also in the stock market. Between 1985 and 1989, Japanese stocks rose 240%... Land prices rose even more, 245% over that four year period."

Non-productive lending subtracts more future growth than it creates in the present.

Banks met loan quotas with no real demand; Nissan made more money speculating than manufacturing; half of top firms' profits came from stock punting.

Why: Misallocated capital raises asset prices today but leaves economy with unproductive overhang and debt service burden tomorrow.

"Investment can always be expected to cause growth, but malinvestment of the type that happened in the Japanese bubble of the 1980s simply subtracts more growth from the future than it causes in the present."

Deflation is self-reinforcing: falling prices → deferred spending → weaker demand → more deflation.

Japan entered a vicious cycle where households postponed purchases expecting lower prices, while real debt burdens rose as incomes fell.

Why: Money gains purchasing power over time, incentivizing hoarding and discouraging consumption or investment.

"Deflation is very harmful to an economy, as when people expect prices to fall, they defer spending, harming the economy more."

Corporate culture that avoids layoffs creates youth unemployment and demographic decline.

Japanese firms retained older workers, slashed new hiring, leading to youth unemployment, delayed family formation, and falling birth rates.

Why: Labor market rigidity protects incumbents but blocks entry for younger cohorts, shrinking future workforce and domestic demand.

"Japanese corporate culture meant that companies avoided laying off workers, so instead they just cut down on new hires. This meant that young people didn't get good jobs, causing further economic stagnation."

Zero or negative rates plus quantitative easing lose effectiveness once deflation expectations set in.

BoJ pioneered QE, bought 70% of JGBs, corporate bonds, and stocks, yet underlying inflation remained weak and wages stagnant.

Why: When households and firms expect persistent deflation, ultra-loose monetary policy mainly inflates asset prices rather than real demand.

"In recent years, Japan went all in with negative interest rates and huge quantitative easing to spur inflation, hoping that it would kickstart the economy."
