Grave of the Fireflies (1988)

Set in Japan during World War II, the film focuses on Seita and his little sister Setsuko. After their mother is killed in an air raid and with their father serving in the navy, they are forced to fight for survival in the devastated Japanese countryside. Food and shelter are scarce, and even their own relatives are too concerned with their own survival. All they have is each other and their belief that life must carry on. Takahata and his team, including character animator Yoshifumi Kondo (who has subsequently worked on other acclaimed Ghibli films from director Hayao Miyazaki) have created a visually stunning and emotionally powerful film that meditates on the devastating consequences of war and has rightly earned a reputation as an anime classic.
