TOPIX (Tokyo Stock Price Index)
How the TOPIX Measures the Performance of Japan’s Broad Equity Market
Introduction
The TOPIX (Tokyo Stock Price Index) is one of Japan’s most important stock market indices and serves as a broad benchmark for the country’s equity market. Unlike the Nikkei 225, which tracks a fixed number of companies, the TOPIX includes a much wider range of listed businesses, providing a more comprehensive view of Japan’s corporate sector and economic performance.
Because of its broad market coverage, the TOPIX is widely used by institutional investors as the primary benchmark for Japanese equities.
The History of TOPIX
The TOPIX was introduced in 1969 by the Tokyo Stock Exchange to provide a comprehensive measure of Japan’s stock market. Over time, it has become the preferred benchmark for many professional investors due to its broader representation of listed companies and market-capitalization weighting.
Today, the TOPIX remains one of Asia’s most influential equity indices.
How TOPIX Works
The TOPIX tracks a broad universe of companies listed on the Tokyo Stock Exchange Prime Market. It is free-float market-capitalization weighted, meaning larger publicly available companies have a greater influence on the index.

This broad coverage provides a comprehensive picture of Japan’s equity market.
