Grave of the Fireflies (火垂るの墓) is a 1988 Japanese animated drama film written and directed by Isao Takahata and animated by Studio Ghibli. It is based on the 1967 semi-autobiographical novel of the same name by Akiyuki Nosaka. It is commonly considered an anti-war film, but this interpretation has been challenged by some critics and by the director.
Grave of the Fireflies received positive reviews from film critics. Roger Ebert of the Chicago Sun-Times considered it to be one of the best and most powerful war films and, in 2000, included it on his "Great Movies" list. Two live-action remakes of Grave of the Fireflies were made, one in 2005 and one in 2008.
