Tokyo Stock Exchange

Tokyo Stock Exchange (TSE; Tōkyō Shōken Torihikijo, 東京証券取引所), is the largest stock exchange in Japan and one of the world's largest securities exchanges by market capitalization of listed companies. Located in the Nihonbashi Kabutochō district of Tokyo, the exchange provides a marketplace for the trading of stocks, exchange-traded funds (ETFs), real estate investment trusts (REITs), preferred stocks, and other financial instruments. The Tokyo Stock Exchange is operated by the Japan Exchange Group (JPX), a publicly listed financial services company formed through the merger of the Tokyo Stock Exchange Group and the Osaka Securities Exchange in 2013. The exchange serves as the principal securities market in Japan and is home to many of the country's largest corporations.

History

The Tokyo Stock Exchange was established on 15 May 1878 under the direction of the Meiji government as part of Japan's modernization of its financial and capital markets following the Meiji Restoration. Trading commenced on 1 June 1878, providing an organized marketplace for the issuance and trading of government bonds and corporate securities.

During the late nineteenth and early twentieth centuries, the exchange expanded alongside Japan's industrialization and economic development. Trading activities were suspended during the final stages of the Second World War, and the exchange formally closed in 1945.

The Tokyo Stock Exchange was reorganized under the Securities and Exchange Act (Japan) and reopened on 16 May 1949. During the post-war economic expansion, it became one of the world's largest securities markets, reflecting Japan's rapid industrial growth and increasing participation in international financial markets.

In 2013, the Tokyo Stock Exchange merged with the Osaka Securities Exchange to form the Japan Exchange Group, creating one of the world's largest exchange groups.
