Tokyo Actor's Consumer's Cooperative Society
In 1959, the Japanese national broadcasting organization NHK was recruiting "tarento" for television, and Katō subsequently moved the NHK's actor training school. The following year in April 1960, she made her broadcast debut in NHK's "Tenshi no Heya", and in the same year, she was also the founder of a theatrical troupe called "Sanju Jinkai". She was also a member of three voice acting offices: the Tokyo Actor's Consumer's Cooperative Society, and Sigma Seven.
