As a Japanese diplomat in Lithuania in the 1940s, Chiune Sugihara had a chance to help thousands of Jews escape the Holocaust through Japan, but it was against his government's orders. When his five-year-old son Hiroki asked, "If we don't help them, won't they die?" Sugihara decided to assist the refugees.

Based on Hiroki Sugihara's own words, Passage to Freedom is the first fully illustrated children's book to tell Sugihara's heroic story, highlighting his courageous humanity, and the importance of a child's opinion in his father's decision.
