|This article is about a/an actor in Kamen Rider Stronger.|
Born Kyoko Hanada, she was given her stage name by the president of Toei at the time, Shigeru Okada. For several years she maintained a very close friendship with Takeshi Sasaki (Hayato Ichimonji/Kamen Rider #2) even after they had both left the series.
Okada studied ballet and in one fight scene in Kamen Rider Stronger can be seen executing a ballet turn. She was asthmatic, however, so the contrivance of her trademark "Electro Wave Toss" was developed to allow her to do only a minimum of stage fighting.
She married Kamen Rider Series makeup artist Hideo Koyama in 1976 and retired.
She died at the age of 27 due to a severe asthma attack. Takeshi Sasaki was reportedly deeply shocked upon receiving news of her death.
