R&D History

"Our efforts are for the good of the people, the community and the future. In any age, our mission is to give a form to 'tomorrow'."

Our mission started with the creation of a network that connects people to people. Our continuing future-focused challenge has been to evolve the network, produce a mechanism to connect people with information, and develop and expand multimedia. Our mission is now looking to the first half of the 21st century, when multimedia will flourish. It will see information being shared over the network, at cybershops and in the form of digital cash. To make this vision of well-developed "Information Sharing Society" a reality, NTT is meeting the challenge of developing more convenient and versatile services, and researching into a secure and low-cost, high-speed network that will support these services.
