The Ballad of Narayama (1958)
The concept of ubasute is at the centre of The Battle of Narayama, the 1958 film by Japanese director Keisuke Kinoshita. Ubasute is the alleged practice of abandoning an infirmed or elderly relative on a mountain or some other remote locale. The practice apparently took place in times of famine or drought, with the idea being that the elderly person’s death would lessen the burden on younger villagers.
