The Japanese Economic Miracle (1950–1990) and the Asset Bubble

The Miracle: 1945 to 1980

In 1945, Japan was a devastated country: two atomic bombs, all industrial cities bombed, its navy destroyed, and the economy in collapse. Per capita income was comparable to that of India.

Forty years later:

• Second-largest economy in the world by GDP
• Toyota and Honda dominate the global automotive industry
• Sony, Panasonic, and Hitachi are leaders in consumer electronics
• Japanese banks are the largest in the world by market capitalization

Factors behind the miracle:

1. Keiretsu: industrial conglomerates intertwined with banks (Mitsubishi, Mitsui, Sumitomo)
2. MITI (Ministry of International Trade and Industry): strategic state industrial planning
3. Very high savings rate: the Japanese saved 20-30% of their income
4. Bretton Woods Agreements: an artificially low yen favored exports
5. Korean and Vietnam Wars: US military procurement stimulated Japanese industry
6. Education and work ethic: absolute dedication to quality (Kaizen, Toyota Production System)

The 1980s Bubble: The Euphoria

In the 1980s, the Japanese economy seemed unstoppable. Stock prices and real estate began to soar, fueled by easy credit and unlimited optimism.

The bubble's absurd numbers:

• The value of the Tokyo Imperial Palace land was equal to the value of all land in California
• Nikkei 225 index: from 6,849 (1982) to 38,916 (December 1989) — +468% in 7 years
• The average P/E ratio of the Japanese stock market reached 60x (versus a historical average of 15-20x)
• The Japanese stock market was worth more than the American one in 1989

The 'rare earth' of the Tokyo real estate market: Japanese companies bought prestigious American assets: Columbia Pictures (Sony), Rockefeller Center (Mitsubishi). It seemed like Japan was buying America.

The Crash (1990–2003)

The Bank of Japan, concerned about asset inflation, raised interest rates from 2.5% to 8% between 1989 and 1990. The bubble burst.

The Nikkei:

• December 1989: 38,916 points
• August 1992: 14,309 points (-63%)
• April 2003: 7,831 points (-80% from the peak)

Real estate prices in Japanese cities collapsed by 70-80% in 15 years. Banks were left with massive portfolios of non-performing loans (NPLs).

The 'Lost Decade' (which became Two Decades)

Japan entered a structural deflation that lasted two decades. The main problem was that banks, rather than acknowledging losses and resetting, kept non-performing loans on their balance sheets — the so-called 'zombie companies' that continued to receive loans without ever becoming profitable again.

This strategy of bank 'forbearance' prevented the creative liquidation of the economy and prolonged the stagnation.

The 'Lost Decade' by the numbers:

• GDP: average growth +1% in the 90s (versus +4% in the 80s)
• Deflation: prices in constant decline (-1% annually for 10 years)
• Unemployment: doubled (from 2% to 5%)
• Nikkei: has still not recovered to 1989 levels (35 years later!)

Lessons for the World

Japan has become the world's laboratory for studying the consequences of an asset bubble and the incorrect response:

1. Recognizing losses immediately is better than hiding them: zombie banks prolong the crisis
2. Deflation is almost impossible to combat: once it takes hold, expectations become self-fulfilling
3. Markets can remain suppressed for decades: the 1989 Nikkei has not been recovered for 35 years
4. Demographics matter: the aging of the Japanese population contributed to the stagnation
