What was the last trading day of Japan's Nikkei peak before its 1990s crash?

Japan's Nikkei reached its pre-crash peak on December 29, 1989.

The Nikkei 225 closed at 38,915.87 on December 29, 1989, its record closing level for many years. The peak marked the end of Japan's asset-price bubble, during which land and equities rose dramatically amid abundant credit, optimistic expectations, and financial deregulation.

The bubble began to deflate after the Bank of Japan raised interest rates and authorities tightened credit. Stock and land prices then fell, damaging banks, businesses, and household balance sheets. Japan entered a prolonged period of weak growth and financial stress often called the Lost Decade, although economic difficulties extended beyond the 1990s.

The date is sometimes confused with the Nikkei's intraday high, which was reached on December 29 as well, at a level slightly above the closing figure. The stock-market peak also preceded the property-market peak, so the crash unfolded over several years rather than in one session.
