Career
She has made over 150 films in her career including such classics as Miyamoto Musashi and Akō Rōshi. While attending Amagasaki High School in Amagasaki, Japan, she was selected as Mission Cinderella in 1953 for a “Japan Cinderella Princess Contest” held by Radio-Keith-Orpheum Radio & Film Company in conjunction with Mainichi Shinbun. Crowned as Mission Cinderella, Oka was invited to visit Hollywood and Disney Studios in March 20 to April 4, 1953.
During her two week visit, Oka was invited to visit and dine with actors such as Ann Blyth and Cary Grant.
A full article of this trip was featured in the July issue of Eiga Number Tomo magazine in 1953. As this trip took place prior to the liberalization of foreign travel, it was then considered to be a valuable trip to Hollywood.
After high school, Oka worked as an office secretary at Radio-Keith-Orpheum Radio & Film Company before being scouted by Toei Studios in 1955. Debuting the same year in “Shinsengumi’s The Black Hooded Seer”, she quickly gained popularity and was referred to as Toei"s "Princess" from the many roles she played as a heroine.
