72 years after the end of World War II, a group of about a dozen people visited Japan. They were born and raised in Vietnam yet consider Japan their homeland in some sense. Their fathers were Japanese soldiers who remained in Vietnam after the war, to fight for the country's independence from France. About 70 of these soldiers had families in Vietnam but suddenly went back to Japan without saying a word. The group from Vietnam arrived in Japan in October of 2017, chasing their fathers' shadows.
