NTT, in collaboration with NTT Group companies and many people from other industries, conducts research and development on new technologies and addresses concerns linked to safety, disaster avoidance, and sustainable development, with the goal of resolving social issues.
The company became involved in data communications. NTT was a crucial element in Japan’s dominance of the computer microchip industry due to its demand for increasingly advanced electronics equipment and its capacity to deploy huge financial resources to assist technology research and development. Non-telephone linkage solutions for computer data systems and fiber-optic telecommunications networks were developed by the business in the 1980s. NTT was privatised in 1985, and since then, it has competed with other Japanese telecommunications providers.
