This film was shot in an ruined house that once stood in Shibuya Udagawa-cho, Tokyo. The block where the house located was a redevelopment area. Shibuya, known as one of Tokyo's most popular bustling street, has an area where old building are still clustered together, and the surrounding area has become like a ghost town. "Plants retreat when people set foot in the area, on the other hand, they multiply as soon as people are gone." (Hiroyuki Sekine)
