The station was established in 1951 by the Society of St. Paul to promote Catholic religion on the Japanese culture.

[1] At the time of its opening, the mission was to "improve Japanese culture, spread the ideals of truth, goodness, justice, and a sound democratic ideology based on humanity , and contribute to the rise of the nation and the prosperity of the people".

However, due to self-righteous management by Priest Paolo Marcelino of the Sisters of St. Paul, who was in charge, and the hiring of a large number of employees who had been red-purged from NHK at the time of its opening, labor disputes occurred frequently, and religious overtones occurred.

[2] The business world, feeling a sense of crisis, decided to take countermeasures in cooperation with publishers such as Obunsha and Kodansha, as well as companies from all over the world, and as a result, the Sisters of St. Paul and the Sisters of St. Paul were forced to withdraw from the management of the station.

Society of St. Paul holds 30 percent of the station's shares, followed by Shogakukan (17.1%), Kodansha (9.0%) and Dai Nippon Printing (8.5%).
