NTT DOCOMO, Inc.(株式会社NTTドコモ Kabushiki Gaisha Enu Ti Ti Dokomo) 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 compound word dokomo, meaning "everywhere" in Japanese. Docomo provides phone, video phone (FOMA and Some PHS), i-mode (internet), and mail (i-mode mail, Short Mail, and SMS) services. The company's headquarters are in the Sanno Park Tower, Nagatachō, Chiyoda, Tokyo. At the beginning of 2015, it was the fourth largest public company in Japan when measured by market capitalization.
Docomo was spun off from Nippon Telegraph and Telephone (NTT) in August 1991 to take over the mobile cellular operations. It provides 2G (mova) PDC cellular services on the 800 MHz band, and 3G FOMA W-CDMA services on the 2 GHz (UMTS2100) and 800 MHz (UMTS800 (Band VI)) and 1700 MHz (UMTS1700 (Band IX)) bands, and 4G LTE services. Its businesses also included PHS (Paldio), paging, and satellite. Docomo ceased offering a PHS service on January 7, 2008.
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 33.71% 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 subscribers in Japan. NTT Docomo is the creator of W-CDMA technology as well as mobile i-mode service. In late 1995, Docomo CEO hired the consulting firm PricewaterhouseCoopers for strategy development, and at that time worked on the first design of data services on mobile for NTT Docomo CEO.
