NTT DoCoMo, Inc. (株式会社エヌ・ティ・ティ・ドコモ, Kabushiki-gaisha Enutiti Dokomo^?, TYO: 9437, NYSE: DCM, LSE: NDCM) is the predominant mobile phone operator in Japan. The name is officially an abbreviation of the phrase, "Do Communications Over the Mobile Network", and is also from a word dokomo, meaning “everywhere” in Japanese.

DoCoMo was spun off from Nippon Telegraph and Telephone (NTT) in August 1991 to take over the mobile cellular operations. DoCoMo provides 2G (mova) PDC cellular services in 800 MHz and 1.5 GHz bands (total 34 MHz bandwidth), and 3G (FOMA) W-CDMA services in the 2 GHz (1945-1960 MHz) band. Its businesses also include PHS (Paldio), paging, and satellite. DoCoMo has announced that its PHS services will be phased out over the next few years.

DoCoMo provides phone, video phone (FOMA and Some PHS), i-mode (internet), and mail (i-mode mail, Short Mail, and SMS) services.

On October, 2007, the prototype Wellness mobile phone of Japan's NTT DoCoMo Inc. and Mitsubishi Electric Corp., was launched at the CEATEC. It gives health check with a motion sensor that detects body movement and measures calories, and, has a breathalyzer. ^[1]

NTT DoCoMo is a subsidiary of Japan's incumbent telephone operator NTT. The majority of NTT-DoCoMo's shares are owned by NTT (which is 31% to 55% government-owned). While some NTT shares are publicly traded, control of the company by Japanese interests (Government and civilian) is guaranteed by the number of shares available to buyers. It provides wireless voice and data communications to many subscribers in Japan. NTT DoCoMo is the creator of W-CDMA technology as well as mobile i-mode service.

NTT DoCoMo has more than 50 million customers, which means more than half of Japan’s cellular market. The company provides a wide variety of mobile multimedia services. These include i-mode which provides e-mail and internet access to over 50 million subscribers, and FOMA, launched in 2001 as the world's first 3G mobile service based on W-CDMA.

In addition to wholly owned subsidiaries in Europe and North America, the company is expanding its global reach through strategic alliances with mobile and multimedia service providers in Asia-Pacific and Europe. NTT DoCoMo is listed on the Tokyo (9437), London (NDCM), and New York (DCM) stock exchanges.

While most mobile operators globally do not perform any significant R&D and rely on equipment suppliers for the development and supply of new communication equipment, NTT DoCoMo continues the NTT tradition of very extensive R&D efforts. It was mainly DoCoMo's strong R&D investments which allowed DoCoMo to introduce 3G communications and i-mode data services long before such services were introduced anywhere else in the world.

NTT DoCoMo has a wide range of foreign investments. However, NTT DoCoMo was not successful in investing in foreign carriers. DoCoMo had invested very large multi-billion dollar amounts in KPN, Hutchison Telecom (included 3, Hutch, etc.), KTF, AT&T Wireless, and had to write-off or sell all these investments in foreign carriers. As a result, DoCoMo booked a total of about US$ 10 billion in losses, while during the same time DoCoMo's Japan operations were profitable.
