[i]The Grave of the Fireflies[/i] is indeed a masterpiece. I recently shared the dubbed version with my ten-year old who was enthralled and deeply moved. I recommend those who've already seen it a few times to seek out Mamoru Shinzaki's HADASHI NO GEN from 1983. Again this is WW II from a Japanese's child point of view, but it deals more specifically with the nuclear Holocaust in Hiroshima and attitudes towards the Japanese government's policies. Widely available on Image dvd.
