Nippon Telegraph and Telephone Corporation (日本電信電話株式会社 Nippon Denshin Denwa Kabushiki-gaisha, TYO: 9432, NYSE: NTT, LSE: NPN), commonly known as NTT, is a telephone company that dominates the telecommunication market in Japan. Ranked the 54th in Fortune Global 500, NTT is the largest telecommunications company in Asia, and the third-largest in the world in terms of revenue.
While NTT is listed on Tokyo, New York, and London stock exchanges, 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.).[1]

[edit] History
Once established as a monopoly government-owned corporation in 1953, Nippon Telegraph and Telephone Public Corporation (日本電信電話公社 Nippon Denshin Denwa Kōsha), the company was privatized in 1985 to encourage competition in the telecom market.
Because NTT owns most of the last mile, it enjoys oligopolistic control over land lines in Japan. In order to weaken NTT, the company was divided into a holding company (NTT) and three telecom companies (NTT East, NTT West, and NTT Communications) in 1999. The NTT Law regulating NTT East and West requires them to serve only short distance communications and obligates them to maintain telephone service all over the country. They are also obligated to lease their unused optical fiber (dark fiber) to other carriers at regulated rates. NTT Communications is not regulated by the NTT Law.
[edit] Subsidiaries
NTT Group consists of the following major companies, divided into five segments. NTT East, NTT West, NTT Communications, NTT DoCoMo, and NTT Data are most major subsidiaries. NTT DoCoMo and NTT Data are listed on the stock markets.
