The index for the Tokyo Stock Exchange is called the Nikkei 225. Since 1950 it has been calculated daily by the Nihon Keizai Shimbun newspaper. It is a price-weighted average of over 1,700 stocks. It is for the most part a Japanese version of the Dow Jones Industrial Average in the U.S. The Nikkei average hit its highest point on December 29, 1989, reaching 38,957.44 and then closing at a slightly lower 39,915.87. Another commonly used index in Japan is the TOPIX index.
