In September 1945, after the end of World War II, Masaru Ibuka started a radio repair shop in the bomb-damaged Shirokiya department store building in the Nihonbashi district of Tokyo. The next year, he was joined by his wartime research colleague, Akio Morita, and on May 7, 1946, they founded a company called Tokyo Tsushin Kogyo K.K. (Tokyo Telecommunications Engineering Corporation). The company produced Japan's first tape recorder, called the Type-G.
