Historical Background
Formation and Early Years
NTT was originally established as a government-owned corporation in 1952, following the reorganization of the Ministry of Communications. The primary objective was to rebuild and modernize Japan's telecommunications infrastructure, which had been severely damaged during World War II. The company was tasked with providing reliable and affordable telecommunication services to support Japan's post-war economic recovery.
Privatization and Expansion
