Abstract
At the end of March 1964, the Nippon Telegraph and Telephone Public Corporation (NTT) had 8.6 million telephones (5.5 million subscriber lines) and 15.2 million circuitkilometers of toll trunks. There are still 1.3 million unfilled telephone application's and there is also a strong demand for complete nationwide subscriber dialing. In order to meet these demands, NTT established a series of five-year expansion programs. On the other hand, all telecommunication services in Japan, such as local and long distance telephone, telegraph, data transmission service, etc., are presently showing remarkable improvement in line with salient technological developments of various electrical communications media.
