Quote from : The Girl Who Leapt Through Time Movie

Kazuko Yoshiyama: It's a mysterious painting. If you look at it for a long time, you feel completely at peace. We don't know its artist, or whether it even has any artistic value. But... we learned one thing during the restoration. This painting was drawn hundreds years ago in a time of war and famine.
Makoto Konno: Why did someone draw this painting when the world was on the verge of destruction?
