Tokyo Stock Exchange (TSE) — Japan’s Primary Stock Market
How the TSE Works
The TSE operates as a fully electronic, order-driven exchange. After a major restructuring in April 2022, the exchange reorganized its market segments from five sections into three: Prime Market (large-cap companies with high governance standards), Standard Market (mid-cap companies meeting basic listing criteria), and Growth Market (high-growth companies, similar to Nasdaq‘s focus). This overhaul aimed to improve corporate governance and attract more foreign investment into Japanese equities.

Major Indices on the TSE
The Nikkei 225 is a price-weighted index of 225 large-cap Japanese companies — similar in methodology to the Dow Jones. TOPIX (Tokyo Stock Price Index) is a broader, market-cap-weighted index covering all Prime Market stocks, making it more representative of the overall Japanese market. Institutional investors and index funds tend to benchmark against TOPIX rather than the Nikkei.
Why Japan’s Market Matters
Japan has the third-largest economy in the world and the TSE lists global leaders in automotive (Toyota, Honda), electronics (Sony, Keyence), and industrial manufacturing. The market saw a major resurgence in 2023-2024, partly driven by corporate governance reforms that pushed companies to unwind cross-shareholdings and return more capital to shareholders through buybacks and dividends. Warren Buffett’s high-profile investments in Japanese trading houses further boosted global interest.
