Overview
NTT Docomo Business is the business telecommunications and information and communications technology organization identified in the supplied reference as the successor to NTT Communications Corporation. Historically operating under the NTT Communications name, the company was established in July 1999 as a subsidiary of Nippon Telegraph and Telephone Corporation following changes to Japan’s telecommunications policy and regulatory framework. Its original remit included long-distance and international telecommunications, complementing NTT’s regional communications companies and the wider NTT Group’s mobile, data communications, and systems-integration businesses. The company’s activities extend beyond traditional voice connectivity. Its portfolio has included enterprise network services, virtual private networks, Internet connectivity, data-center operations, cloud services, managed services, consulting, and other ICT capabilities. These services are designed for corporations, multinational organizations, and government agencies that require managed communications infrastructure across domestic and international locations. The company’s international network has been described as reaching more than 190 countries and regions, supported by locations in more than 70 countries and regions. Its scale has also included a Japan-based workforce of approximately 5,500 employees and an NTT Communications Group workforce of approximately 11,500 employees as of March 2020. During its early years, NTT Communications developed international calling and enterprise technology services. In 2000 it introduced the 0033 SAMURAI Mobile international calling service, intended to reduce the cost of international calls, and expanded data-center services in Japan and overseas to support corporate electronic commerce. A 2001 licensing agreement with InterWise enabled the company to offer software-based live electronic-learning and collaboration capabilities to business customers. In 2003, after Crosswave Communications entered bankruptcy, NTT Communications took over its operations and agreed to acquire the business for approximately ¥10 billion, according to the cited reference material. The company subsequently broadened its domestic hosting, international network, data-center, and managed-cloud capabilities. It launched OCN Hosting Service, also referred to as a new Open Computer Network hosting service, in 2006 with an emphasis on small and medium-sized enterprises. International expansion included investment in Australian IT services, the creation of NTT ICT from Frontline Systems and NTT Australia, additional points of presence in Europe, and participation in the Asia Submarine-cable Express system linking major Asian markets. It also developed partnerships and solutions involving hybrid IT, disaster recovery, video conferencing, and industrial artificial intelligence. Technology infrastructure has remained central to the organization’s positioning. In 2013 it deployed 100 Gbit/s Ethernet technology on a cable system connecting Japan and the United States, while its data-center activities included energy-efficiency measures such as cooling-wall systems, water-side economization, renewable-energy installations, and smart lighting. The company has received international industry recognition, including World Communication Awards for customer care and global operator performance, and was placed in Gartner’s Leaders quadrant for managed hybrid cloud hosting in Asia-Pacific in 2017. The supplied reference identifies the organization as NTT Docomo Business, while much of the historical material concerns the NTT Communications corporate identity. Its business scope is therefore best understood as enterprise connectivity and managed ICT within the NTT corporate family, with Japan as its home market and a substantial international operating footprint.
History
NTT Docomo Business traces its historical business identity to NTT Communications Corporation, which was created in July 1999 as part of the restructuring of Japan’s telecommunications sector. The policy changes preceding its creation opened the way for a dedicated NTT subsidiary responsible for long-distance and international communications, while NTT’s regional companies continued to focus primarily on local telecommunications. Nippon Telegraph and Telephone Corporation became the parent company. The early business combined voice, data, international connectivity, and emerging Internet infrastructure. In 2000 the company launched 0033 SAMURAI Mobile, an international calling service intended to provide lower international calling charges. It also began developing data-center services in Japan and overseas for companies conducting electronic commerce. In 2001, a licensing agreement with InterWise added software-based live electronic learning and collaboration capabilities to its enterprise offering. In December 2003, NTT Communications took over the operations of Crosswave Communications after that company entered bankruptcy proceedings and agreed to acquire it for approximately ¥10 billion, as reported in the supplied reference material. The company expanded its hosting and enterprise network capabilities in the following decade. In 2006 it introduced OCN Hosting Service, described as a new Open Computer Network hosting service aimed mainly at small and medium-sized businesses. Its international growth included a 2011 investment for a majority stake in Australian IT services provider Frontline Systems. Frontline Systems was later combined with NTT Australia to form NTT ICT in 2013. Network capacity and international reach became prominent elements of the company’s development. In July 2013 it deployed 100 Gbit/s Ethernet technology on a cable route connecting Japan and the United States, increasing the system’s capacity by a reported 2.5 times. In August 2012 it launched the Asia Submarine-cable Express in cooperation with telecommunications companies including Telekom Malaysia, PLDT, and StarHub. The system connected Japan, Malaysia, the Philippines, Singapore, and later Hong Kong, supporting access to data centers, cloud services, and network infrastructure. NTT Communications also developed an international data-center and network presence. Its activities included a Tier-1 Global IP Network point of presence in Munich and data-center infrastructure in China and Hong Kong. The Financial Data Center Tower 2 project incorporated cooling walls, water-side economization, solar panels, smart lighting, and other measures intended to reduce energy consumption. In India, NTT Communications India opened additional offices in Ahmedabad and Gujarat in 2015 to support ICT solutions. Partnerships broadened the company’s service portfolio. An alliance with Dimension Data addressed hybrid IT and global software-based network services. Cooperation with Geminare supported the expansion of Disaster Recovery as a Service into Europe, while work with Arkadin supported video-conferencing services for Japanese organizations and multinational companies. NTT Communications also worked with Mitsui Chemicals on deep-learning-based prediction technology for industrial process data. Recognition accompanied this expansion. In 2005 the company received the Best Customer Care award at the World Communication Awards, becoming the first Asian company to receive that communication-sector award according to the supplied reference. In 2014 it received Best Global Operator recognition at the World Communications Awards, and in 2017 Gartner placed it in the Leaders quadrant for managed hybrid cloud hosting in Asia-Pacific. The organization has also been associated with sponsorships involving rugby, McLaren, Tokyo Disney Resort attractions, and NANOG events. A significant security incident was disclosed in May 2020. NTT Communications reported that attackers had gained unauthorized access to company facilities and that some information might have been leaked externally; the cited material states that consumer-customer information was not involved. The current NTT Docomo Business identity should be read alongside this historical record, much of which was published under the NTT Communications name.
