NTT EAST Corporation (formerly Nippon Telegraph and Telephone East Corporation)

NTT EAST is the NTT Group's regional telecommunications carrier responsible for communications infrastructure across eastern Japan—1 metropolis and 15 prefectures from Hokkaido to Nagano and Yamanashi. Its core business is the construction, operation, and maintenance of fixed-line services such as the “FLET'S HIKARI” fiber-optic broadband service and “Hikari Denwa” optical IP telephone service, together with ICT solutions that support digital transformation at companies and local governments. Because its territory includes the greater Tokyo area and many government agencies and large corporate customers, employees must adapt to a strongly regional business, substantial public responsibility, and a steady, rules-oriented organizational pace rather than the rapid iteration culture of an internet startup.
