She made her acting debut in 1951 in Noboru Nakamura's film Home Sweet Home.

In the 1950s, David Lean proposed her for the main role in The Wind Cannot Read, which is about a Japanese language instructor in India circa 1943 who falls in love with a British officer, but that idea fell through and Yoko Tani was eventually cast in the role.

Kishi married the French director Yves Ciampi in 1957, and commuted for a while between Paris and Japan to continue her acting career. In 1963 a daughter was born. She divorced her husband in 1975. She has two grandchildren by her daughter.
