Tokyo Metro (company)
Open-knowledge reference entry

The Tokyo Metro Co., Ltd. (Japanese: 東京地下鉄株式会社, Hepburn: Tōkyō Chikatetsu kabushiki gaisha; lit. 'Tokyo Subway Share Company') is a tokushu gaisha (state-owned joint-stock company) jointly controlled by the Government of Japan and the Tokyo Metropolitan Government. It operates nine subway lines and is also engaged in real estate, retail and education in the Greater Tokyo Area.
Tokyo Metro was privatized and established as a private company on April 1, 2004, succeeding Teito Rapid Transit Authority (TRTA) and shifting to a more commercial model while maintaining public service obligations.
In 2024, the company made its initial public offering, raising $2.3 billion in what became Japan's biggest IPO since 2018. Tokyo Metro was listed on the Tokyo Stock Exchange, debuting as the exchange's largest IPO in six years and with a market capitalization of roughly 1 trillion yen. The Government of Japan and the Tokyo Metropolitan Government each sold half of their shares, with the former using the proceeds to repay bonds funding reconstruction after the 2011 Tōhoku earthquake and tsunami.
History
The Tokyo Underground Railway Company was founded on August 29, 1920, with the aim of developing Japan's first underground railway at a time when Tokyo was experiencing rapid urban growth. Although construction commenced in 1925, progress was hindered by economic difficulties following the Great Kantō earthquake of 1923, which caused widespread destruction and diverted resources away from major infrastructure projects. Nevertheless, the company inaugurated the first 2.2-kilometre segment of what is now the Ginza Line on December 30, 1927, linking Ueno and Asakusa and becoming the first subway line in Asia.

Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q137823009. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2004, 2024, 2018 and 2011.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
