During World War II (1945), a Japanese boy stood in front of a funeral pyre and waited his turn to cremate his dead younger brother.
The person who took the photo said in an interview that the boy was biting his lip so hard to keep from crying that blood was dripping from the corner of his mouth.
It was then that the guard asked for the body and said, "Give me the load you are carrying on your back." And the boy replied, "He's not heavy, he's my brother."
He handed over the body, turned around and left... In Japan, even today, this image is used as a symbol of strength.
