The Nikkei 225, or the Nikkei Stock Average , more commonly called the Nikkei or the Nikkei index, is a stock market index for the Tokyo Stock Exchange (TSE). It is a price-weighted index, operating in the Japanese Yen (JP¥), and its components are reviewed twice a year. The Nikkei 225 measures the performance of 225 highly capitalised and liquid publicly owned companies in Japan from a wide array of industry sectors. Since 2017, the index is calculated every five seconds. It was originally launched by the Tokyo Stock Exchange in 1950, and was taken over by the Nihon Keizai Shimbun newspaper in 1970, when the Tokyo Exchange switched to the Tokyo Stock Price Index (TOPIX), which is weighed by market capitalisation rather than stock prices.

The Tokyo Stock Exchange , abbreviated as Tosho (東証) or TSE/TYO, is a stock exchange located in Tokyo, Japan.

The Japanese asset price bubble was an economic bubble in Japan from 1986 to 1991 in which real estate and stock market prices were greatly inflated. In early 1992, this price bubble burst and the country's economy stagnated. The bubble was characterized by rapid acceleration of asset prices and overheated economic activity, as well as an uncontrolled money supply and credit expansion. More specifically, over-confidence and speculation regarding asset and stock prices were closely associated with excessive monetary easing policy at the time. Through the creation of economic policies that cultivated the marketability of assets, eased the access to credit, and encouraged speculation, the Japanese government started a prolonged and exacerbated Japanese asset price bubble.
