- The basic plot is centered on the great cherry tree Tarōzakura and what happens after it is cut down during the making of a movie. The fourth film is the subject of much debate, as it is probably the hardest of all the Urusei Yatsura films to fully understand. Many consider it to be a multi-layered masterpiece, while others feel it is little more than a confused and rambling mess.
- A Making of Urusei Yatsura 4: Lum the Forever (メイキング・オブ・うる星やつら4 アニメ製作の実際?) documentation about the film was released on 15 February 1986.
