The story

Establishment and early years (1996–2005)

In 1996, several new policies were issued for the Telecommunications Law, and as a result of this policy change, NTT Communications Corporation was established in July 1999. Since then, Nippon Telegraph and Telephone Corporation (日本電信電話株式会社, Nippon Denshin Denwa Kabushiki-gaisha) has served as a parent company, controlling NTT Communications which is responsible for long-distance and worldwide telephone services and two other local telecom companies.

In 2000, the firm launched new international services called “0033 SAMURAI Mobile”, which were intended to allow users to make an international phone call with reduced international calling fees. Moreover, the firm began Data center services both within Japan and overseas to provide support for E-business conducted by corporations.

On 1 March 2001, NTT Com accepted a license agreement with InterWise, a major provider of live electronic learning and services for software-based enterprises. Due to the agreement, NTT Communications could offer the InterWise system to their customers as a cross-corporation service. From this, the company was able to expand its presence in the electronic learning market by using technology developed by InterWise to encourage information sharing besides development of corporations.

In December 2003, NTT Communications took over operations from a major data communications services provider; Crosswave Communications Inc. (CWC), which had filed for bankruptcy. In addition, NTT Communications reached an agreement to acquire CWC for approximately 10 billion yen, NTT Communications PM Suzuki said.

On 3 October 2005, the company won the Best Customer Care award at the World Communication Awards 2005 held in London, becoming the first Asian company to earn the award in the communication field.

Expansion (2006–2015)

In 2006, NTT Communications started a new Open Computer Network, also known as OCN Hosting Service, serving mainly small and medium-sized enterprises domestically.

In May 2011, NTT purchased 70% of Frontline Systems, an Australian IT services provider. In October 2013, it merged Frontline Systems with NTT Australia to form NTT ICT.

On 17 July 2013, the world's first 100 Gbit/s Ethernet technology on a cable system linking Japan and the United States was deployed by NTT Communications. The technology could enhance the capacity of the company's system by 2.5 times.
