On December 1, 1964, the modern Communications Culture Center is completed in Otemachi in Tokyo's business center, Chiyoda Ward. This building houses a new comprehensive Communications Museum, the cooperative effort of four major sponsors, the Ministry of Posts and Communications, the Nippon Telephone and Telegraph Corporation, the Japaneses International Telephone and Telegraph Corporation (KDD), and the broadcasting authority NHK. Exhibits present easy-to-understand descriptions of communications from ancient times to the space age using actual objects, panoramas, models and recordings played over earphones. Visitors are able to operate some of the exhibits themselves in this museum which combines materials from the past with the course of development for the future.
