NTT Docomo

NTT Docomo, Inc., also known as Docomo, is a Japanese mobile phone operator owned by the Nippon Telegraph and Telephone. 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. The company is headquartered in Sanno Park Tower, Nagatachō, Chiyoda, Tokyo. Docomo provides phone, video phone, i-mode, and mail services. It is the largest wireless carrier in Japan, with 82.632 million subscribers as of March 2021.

Docomo was spun off from NTT in August 1991 to take over the mobile cellular operations. NTT held a majority stake in the company until Docomo's re-privatization in 2020.
