Tokyo Stock Exchange in the context of "Nagoya Stock Exchange"

Japan has a highly developed mixed economy, often referred to as an East Asian model. According to the IMF forecast for 2025, it will be the fourth-largest economy in the world by nominal GDP and the fifth-largest by purchasing power parity (PPP) by the end of the year. It constituted 3.7% of the world's economy on a nominal basis in 2024. According to the same forecast, the country's nominal per capita GDP (PPP) will be $56,440 (2025). Due to a volatile currency exchange rate, Japan's nominal GDP as measured in American dollars fluctuates sharply.

A founding member of the G7 and an early member of the OECD, Japan was the first country in Asia to achieve developed country status. In 2024, Japan was the sixth-largest in the world as an importer and eight-largest as an exporter. The country also has the world's fourth-largest consumer market. Japan used to run a considerable trade surplus, but the decline of the manufacturing sector since the 1980s and increased fossil fuel imports after the Fukushima nuclear accident in 2011 have changed this trend in recent years. Being the world's largest creditor nation, Japan has a considerable net international investment surplus. The country has the world's second-largest foreign-exchange reserves, worth $1.4 trillion. Japan has the third-largest financial assets in the world, valued at $12 trillion, or 8.6% of the global GDP total as of 2020. Japan has a highly efficient and strong social security system, which comprises roughly 23.5% of GDP. The Tokyo Stock Exchange is the world's fourth-largest stock exchange by market capitalisation as of 2025.

Panasonic Holdings Corporation is a Japanese multinational electronics manufacturer, headquartered in Kadoma, Japan.

In 2022, it reorganized as a holding company and adopted its current name.

In addition to consumer electronics, for which it was the world's largest manufacturer in the late 20th century, Panasonic produces a wide range of products and services, including rechargeable batteries, automotive and avionic systems, industrial equipment, as well as home renovation and construction.

NTT, Inc. (formerly known as Nippon Telegraph and Telephone Corporation) is a Japanese telecommunications holding company headquartered in Tokyo, Japan. Ranked 128th in Fortune Global 500, NTT is the sixth largest telecommunications company in the world in terms of revenue, as well as the 15th largest publicly traded company in Japan by market cap, and the 6th largest by revenue, as of November 2025. In 2025, the company was ranked 79th in the Forbes Global 2000. NTT was the world's largest company by market capitalization in the late 1980s, and remained among the world's top 10 largest companies by market capitalization until the burst of the Dot-com bubble in the early 2000s.

The company traces its origin to the national telegraph service established in 1868, which came under the purview of the Ministry of Communications in the 1880s as part of a postal, telegraph and telephone service. In 1952, the telegraph and telephone services were spun off as the government-owned Nippon Telegraph and Telephone Public Corporation. Under Prime Minister Yasuhiro Nakasone, the company was privatised in 1985 along with the Japan Tobacco and Salt Public Corporation and subsequently the Japanese National Railways two years later, adopting the previous name until July 2025. While NTT has been listed on the Tokyo Stock Exchange since 1987, the Japanese government still owns roughly one-third of NTT's shares, regulated by the NTT Law (Law Concerning Nippon Telegraph and Telephone Corporation, Etc.).

The company is active in various industries, including digital systems, power and renewable energy, railway systems, healthcare products, and financial systems. The company was founded as an electrical machinery manufacturing subsidiary of the Kuhara Mining Plant in Hitachi, Ibaraki by engineer Namihei Odaira in 1910. It began operating as an independent company under its current name in 1920.

Hitachi is listed on the Tokyo Stock Exchange and is a key component of the Nikkei 225 and TOPIX Core30 indices. As of June 2024, it has a market capitalisation of 16.9 trillion yen, making it the fourth largest Japanese company by market value. In terms of global recognition, Hitachi was ranked 38th in the 2012 Fortune Global 500 and 129th in the 2012 Forbes Global 2000. Hitachi is a highly globalised conglomerate. In the fiscal year 2023, it generated approximately 61% of its total revenue of 9.7 trillion yen from international markets. The major contributors to this global revenue were Asia, Europe, and North America, with each region accounting for 22%, 16%, and 16% of the total revenue, respectively.

The Nikkei 225, or the Nikkei Stock Average (Japanese: 日経平均株価, Hepburn: Nikkei heikin kabuka), more commonly called the Nikkei or the Nikkei index (/ˈnɪkeɪ, ˈniː-, nɪˈkeɪ/), 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 (The Nikkei) 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 Price Index (東証株価指数, Tōshō Kabuka shisū), commonly known as the TOPIX, is an important stock market index for the Tokyo Stock Exchange (TSE) in Japan, along with the Nikkei 225. The TOPIX tracks the entire market of domestic companies and covers most stocks in the Prime market and some stocks in the Standard market. It is calculated and published by the TSE. As of January 2025, there are planned to be 1,716 companies listed on the TSE, since about 400 stocks with low liquidity were phased out after the TSE reform in 2022.

The index transitioned from a system where a company's weighting is based on the total number of shares outstanding to a weighting based on the number of shares available for trading (called the free float). This transition started in October 2005 and was completed in June 2006. Although the change is a technicality, it had a significant effect on the weighting of many companies in the index, because many companies in Japan hold a significant number of shares of their business partners as a part of intricate business alliances, and such shares are no longer included in calculating the weight of companies in the index.
