The film icon, whose real name was Yoshiko Yamaguchi, was one of the most celebrated Asian actresses in the 1940s and 1950s.
Yamaguchi passed away from heart failure on September 7, Japanese broadcaster Nhk confirmed.
The actress starred in many Chinese-language films during World War II, attracting considerable controversy and legal rebukes from the post-war government.
After the war, she appeared in legendary filmmaker Akira Kurosawa's 1950 classic Scandal, the romantic epic Escape At Dawn and the Hollywood film Japanese War Bride.
She began a political career in 1974, after she was elected to the Japanese House of Councillors as a member of the Liberal Democratic Party. She served until 1992.
