The idea of JAM was conceived while I was attending the Ottawa International Animation Festival in 2008.After returning to Japan, I soon began making the film and completed it in four months.This film is based on a very simple idea: the increasingly varied the sounds, the greater is the number of creatures. I wanted to rid myself of the frustrating experience of making Devour Dinner, which was highly unsatisfactory from the viewpoint of the movement in the film. My intention in this film was to fill the screen with chaotic movements.
