The contracts for the receiving audience on that day numbered approximately 3,500. Radio broadcasting also began in Osaka (June 1) and Nagoya (July 15) that same year.

1925 The Dawn of Broadcasting Culture

Regular Radio Broadcasting

In 1906, the first human voice was transmitted by radio wave. Within a mere decade, the world's first radio broadcaster, KDKA Radio, appeared in Pittsburgh, USA (1920). Its first broadcast included a flash report on the voting results of the U.S. Presidential Election. It is estimated that approximately 15,000 receivers, mostly those of amateur radio operators, could have been tuned in at the time. Radio quickly became popular.

JOAK, Tokyo Broadcasting Station

In Japan, radio broadcasting commenced at 9:30 a.m., on March 22, 1925, two years after the Great Kanto Earthquake. "JOAK, JOAK, J, O, A, K, This is the Tokyo Broadcasting Station." The first radio address broadcast in Japan filled the skies of Tokyo from a temporary broadcasting station in Shibaura, Tokyo. Initial contracts for the receiving audience of this inaugural broadcast numbered approximately 3,500. Radio broadcasting also began in Osaka (June 1) and Nagoya (July 15) that same year. The fact that broadcasting began immediately after the Great Kanto Earthquake (1923) contributed greatly to showing the people of Japan the importance of being able to receiving reliable information via broadcast.


Big Dreams and Roles for Broadcasting

Governor Shinpei Goto of the Tokyo Broadcasting Station gave a famous speech regarding the function of broadcasting at the opening ceremony for the station. In his address, he said "I cannot imagine our cultural life of the future without broadcasting." He assigned big dreams and important roles to broadcasting.
