Horikoshi High School
Born in Manhattan, New York City, United States to Japanese parents, she moved to Kyoto at age 3. Kimiko graduated from Horikoshi High School in Nakano, Tokyo and subsequently attended Tamagawa University. She is closely related to the Bandō Mitsugorō kabuki actors: her grandfather was the eighth, her uncle the ninth (later Bandō Minosuke VII), her cousin (Bandō Yasosuke V) the tenth to take that name. With the encouragement of that cousin, Kimiko turned to acting.
