Developing infrastructure and services that address social issues
In line with the Ministry of Internal Affairs and Communications' u-Japan Policy*1 that calls for the creation of a communications environment utilizing seamless and ubiquitous broadband networks, the NTT Group is working to develop and expand infrastructure and services related to fiber optic services, FOMA 3G mobile communications services, and the next-generation network (NGN)*2.
*1 u-Japan Policy
A government policy that aims to develop ubiquitous broadband networks that seamlessly integrate fixed and wireless networks, and to use these networks to address various social issues.
*2 Next-generation network (NGN)
A network that has been developed and built to provide an infrastructure for communications services required in the age of ubiquitous broadband. The NGN uses high-speed, high-capacity IP networks to provide telephone service and Internet access, and also to enable various services such as video distribution, and linkages with mobile communications networks.

FOMA 3G mobile communications services reach 100% population coverage*1
The NTT DOCOMO Group has been driving the adoption of its FOMA 3G mobile communications services as a mobile network to support ubiquitous broadband communications. In March 2007, FOMA achieved 100% population coverage in Japan.
DOCOMO also expanded its FOMA HIGH-SPEED*2 service area to major cities across Japan. This high-speed data communications service enables the download of music and video content and other services that make mobile network handsets even more useful.
Efforts are under way to expand the HIGH-SPEED service area and to develop handsets with international roaming and other cutting edge capabilities. DOCOMO is also working on raising the speed and capacity and improving communications quality of its FOMA service.
