Rebellion of Japan (1967)

Suzuko, a woman in her twenties who has a brother with political problems (due to communist reprisals), lives for over five years in a love affair with Tate who's a young lieutenant in the Army, ultimately becoming a right-wing fundamentalist revolutionary. She marries another man, one totally dedicated to the rigorous practices of Noh theatre, in an arranged marriage, but the bond that connects her with Tate is too strong.
