Japan's Asset Bubble and the Nikkei's -80%
The saying "stocks always go up if you hold them long enough" was, for Japanese investors, a story that required a 34-year wait. The Nikkei's 1989 peak took a full generation to reach again.
1989, the Peak at Nikkei 38,915
In the 1980s Japan experienced a massive asset bubble in which real estate and stocks soared at the same time. People even said "you could buy the entire United States with the land value of Tokyo."
The Nikkei 225 index hit an all-time high closing price of 38,915.87 on December 29, 1989. At the time many people believed the rise would last forever, but that turned out to be the beginning of a generation-long decline.
A Long Decline of About -80%
Once the bubble burst, the Nikkei collapsed over many years. On April 28, 2003, it fell to 7,603.76 — about -80% below its 1989 high.
Unlike the Great Depression or the dot-com bubble, which hit relatively clear bottoms and then rebounded, Japan declined over more than a decade, repeating rebounds and renewed drops. This was intertwined not only with asset prices but with a prolonged real-economy slump (the lost decades).
To recover your principal from an -80% decline, you need a gain of about +400% (5x). It is an extreme example of how the larger the drop, the more sharply the gain needed to recover grows.
About 34 Years to Recover the High
The Nikkei surpassed its 1989 high again only on February 22, 2024. That day it closed at 39,098.68, setting a new record after about 34 years.
The number 34 years is close to "an individual's entire investing lifetime." Someone who bought at the top in their 20s only recovered their original stake in their 50s. This is a representative example that shows the risks of concentrating investments in a specific country or index, and why international diversification is discussed.
Frequently Asked Questions
Q. Would the recovery have been faster including dividends?
Yes. On a "total return" basis including dividend reinvestment, some analyses suggest recovery came earlier than for the nominal (price) index. Still, even accounting for dividends it took many years, and the symbolic figure of "34 years for the price index high" remains valid for showing the risk of concentrated investing.
Q. Could Japan's case be repeated in other countries?
No one can predict the future of a specific country. But Japan's case shows the risk that "if you bet everything on one country or one asset and that country falls into a long slump, recovery becomes hard to count on." This is why international diversification across many countries and assets is discussed.
