GRAVE OF THE FIREFLIES is a 1988 Japanese animated film written and directed by Isao Takahata and animated by Studio Ghibli.
Set in Japan during World War II, the film tells the story of Seita, a young boy who has to take care of his younger sister Setsuko when their mother dies. Based on a 1967 semi-autobiographical novel of the same name, it is commonly considered an anti-war film, but this interpretation has been challenged by some critics and by the director.
"An emotional experience so powerful that it forces a rethinking of animation." - Roger Ebert
