Docomo was spun off from its parent company Nippon Telegraph and Telephone (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.

It provides 2G (mova) PDC cellular services, 3G (FOMA) W-CDMA, 4G LTE and 5G NR services. Its businesses also included PHS (Paldio), paging, and satellite. Docomo ceased offering a PHS service on January 7, 2008. In late 2020, Docomo was bought back by NTT for about $40 billion.[8]

Customers

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.

NTT Docomo had over 53 million customers (as of March 2008), which is 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, FOMA, which was launched in 2001 as the world's first 3G mobile service based on W-CDMA, Xi, a 4G LTE mobile service which was launched on December 24, 2010, Premium 4G, a LTE Advanced service which was launched on March 27, 2015, and DoCoMo 5G, a 5G NR service which launched on March 25, 2020.

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.

On April 19, 2008, it was announced that Ryuji Yamada, the current co-president of NTT Docomo, will be promoted as the president of NTT Docomo in June 2008. Masao Nakamura will stay in NTT Docomo as a director and also the senior adviser. Since October 2006, when the introduction to the service which allows the user to carry their original phone number with a new provider was made, NTT Docomo has lost many users to KDDI and SoftBank. This promotion was made in order to get more users for NTT Docomo.[9] The company was the last major global mobile carrier to offer Apple's iPhone, which it finally did with the release of the iPhone 5s and 5c. This has been cited as one of the reasons for the steady stream of its customers switching for competing networks.[10]

In June 2011, the company announced that they were teaming up with McAfee to provide McAfee VirusScan Mobile for its Android mobile users.[11] In July 2012, NTT Docomo acquired Italy's Buongiorno in a deal worth 209 million euros.[12]

Research and development

In October 2007, Docomo and Mitsubishi Electric showcased a prototype mobile phone at the CEATEC trade show. The phone checked health by tracking body movement and measuring calories, and included a breathalyzer.[13] On January 24, 2008, NTT Docomo announced a partnership with Google, which allowed all models after the FOMA904i models to view YouTube videos.[14][15] In 2008, NTT Docomo became a founding member of the Symbian Foundation.[16]

In May 2017, Docomo launched 5G trial networks at Aomi, Odaiba (Tokyo Waterfront City) and the area around Tokyo Skytree.[17] It commercially launched its 5G network on March 25, 2020, making it the first Japanese operator to do so,[18] and making Japan among the first country in the world to launch 5G.

In August 2021, Docomo and Airbus demonstrated a solar-powered Zephyr High Altitude Platform Station (HAPS) for use with 5G and 6G technology. The trial took place in the United States over 18 days, and involved flying in the stratosphere and transmitting data at various speeds up to a distance of 140 km. If successful, then Docomo and Airbus would be able to provide communication services to remote islands, mountainous areas, and to remote sea lanes.[19]

Earthquake warning system

From 2008, Docomo began offering a service called the "Area Mail Disaster Information Service" which broadcasts Earthquake Early Warning messages produced by the Japan Meteorological Agency to its subscribers with compatible handsets.[20] This service is provided free of charge and messages are limited to those areas affected by each particular alert. These alerts have a unique ring tone so they can be easily distinguished from incoming calls or messages.

Civil protection system

From 2014, under Civil Protection Law of Japan, Docomo began offering a service called the "Area Mail Disaster and Evacuation Information Service" which broadcasts J-Alert messages (including Earthquake Early Warning) produced by the Japan Fire and Disaster Management Agency to its subscribers with compatible handsets (e.g. Sony XPERIA, iPhone 5s, Samsung Galaxy).[21]

The message is broadcast when threats are imminent (e.g. North Korea's ballistic missile launching, terrorist attack to nuclear power plant, volcanic eruptions, or an approaching tsunami.)

Mascot

The company's mascot is Docomodake, a mushroom, which is quite a celebrity in Japan. He is even the hero of a Nintendo DS puzzle and platforming video game, Boing! Docomodake DS on 2007 and 2009; on 2016 or 2015, Nintendo put a Docomodake Mii in the app they called Miitomo, which was also released in North America, Japan and Europe.[22] He also has a wide variety of merchandising such as cell phone straps, keychains, and plush dolls. As one type of advertising method, there are many types of Docomodakes such as mother and father, which symbolizes the plans that NTT Docomo offers.

Emoji
See also: Decome

Shigetaka Kurita, who was part of the team working on NTT DoCoMo's i-mode mobile Internet platform, that has been credited as the first creator of emoji.[23] This has since been corrected. In fact, SoftBank released their emoji set on the DP-211SW mobile phone in 1997.[24]

Copyright ownership of an emoji typically belongs to the company or organization that created it. For example, the copyright for Apple's emoji designs belongs to Apple Inc. Similarly, the copyright for emoji used on platforms such as Facebook, Twitter, and WhatsApp belong to the respective companies.

It's worth noting that emoji are standardized through the Unicode Consortium, which sets standards for how emoji should look and what they should represent. However, individual companies and platforms can still design their own variations of emoji within those standards.

Investments outside Japan
GSMA Mobile World Congress, Barcelona 2008 99.

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 multibillion-dollar amounts in KPN, KT Freetel, AT&T Wireless, and had to write-off 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.

In December 2007, NTT Docomo and KT Freetel jointly invested US$200 million for a total of 33% stake in U Mobile Malaysia.

In June 2008 NTT Docomo joined the non-profit Symbian Foundation led by Nokia to co-develop a new Symbian smartphone operating system based on the S60 platform, which resulted in Symbian^2 for the Japanese market.[25]

In December 2006 they acquired Guamcell, the largest phone company in Guam, and changed its name to DOCOMO PACIFIC.

Docomo is working on implementing its FeliCa-based payment system, called iD, overseas. It has already launched the system in Guam, as well as Shanghai and Beijing, China (however, as of November 2010, it has withdrawn iD terminals from all merchants in China).

Docomo Capital

Working closely with NTT Docomo's business and R&D divisions, Docomo Capital is in charge of NTT Docomo's venture investments in mobile related start-up companies, mainly in the United States and has committed $100M in capital. It has invested in Cooliris, Couchbase, Evernote, Fab.com, HighlightCam, Swype, TuneWiki, Sigfox and Wiliot.[26][27]

Docomo Digital

Docomo Digital is the international payments business of NTT DOCOMO. DOCOMO Digital partners with carriers, merchants, OTT services, app stores and payment providers in both developed and emerging markets to facilitate direct carrier billing and other payments such as e-wallets. Sold to Bango plc August 2022.

Hikari TV

Hikari TV (ひかりTV) is a Japanese IPTV service. It was established on March 31, 2008, and was originally owned and operated by the internet service provider NTT Plala.[28] It launched Hikari TV Game, the first cloud gaming service for televisions in Japan, in 2013.[29]

On July 1, 2022, NTT Docomo absorbed and merged the operating company NTT Plala, and on the same day, this service was also incorporated into NTT DoCoMo's service.[30][31] Along with this, the rate plan for new subscribers was changed after the same day.[32]

Aside from offering access to various television channels, Hikari TV also produces its own content, primarily broadcast on the Hikari TV Channel.
