Grave of the Fireflies 『火垂るの墓』
After being taken in by a distant relative, fourteen-year-old Seita learns that to be the man in the family comes with great responsibility. Though he works hard every day to shelter his young sister from the events going on around them, he quickly butts heads with his caretakers. Eventually, Seita makes the decision to move out of his distant aunt's home and into an abandoned bomb shelter in the countryside. There, along with the fireflies they catch to serve as their nightlight, Seita and Setsuko learn some hard lessons about life.
Animated by the famed Studio Ghibli, Grave of the Fireflies is a must-see film that has since been remade into two new live action versions. An interesting fact is that Grave of the Fireflies was released as a double feature with Studio Ghibli's My Neighbor Totoro. The topic and tone of the two films could not be more disparate!
Fun Fact: The Chinese characters used in the title of the film are interesting. The traditional character for firefly (蛍) has been replaced by 火垂る, which is read with the same pronunciation but uses the characters for "fire" and "to trickle down" in order to reference the firebombing.
