Kyûba no koibito (1969)

A Japanese sailor arrives in Cuba, willing to know the country and meet its people, after a decade of a revolutionary process. He feels attracted to Marcia, a young Cuban girl, who willingly shows him her country, and tells him about the years of terror that she lived under Fulgencio Batista's regime, when her family was killed. But they will have to make a decision, when she feels more inclined to dedicate her life to the revolution.
