The ferry the Goranger team travel in and relax aboard (while traveling to an island) is called the Sunflower Sapporo, which is a real-life (and still active) ferry. The original owners, Nippon High-Speed Ferries (Nippon Kôsoku Fêrî), was one of this film's sponsors. It was also featured in other tokusatsu (Japanese special effects) films such as Kamen Raidaa Bui Surii tai Desutoron Kaijin (1973) and Godzilla contre Mecanik Monster (1974).
Released as part of the Toei Manga Festival (a kiddie matinee festival), this film was the very first original movie ever produced in the Super Sentai franchise (in 35mm and 2.35:1 anamorphic scope ratio), as opposed to the theatrical release of a TV episode (blown up/cropped into 2.35:1 widescreen from its original 16mm 1.33:1 fullscreen aspect ratio), which was the case of the first and previous film, Goranger: The Movie (1975) (which was actually Episode #6 of Himitsu Sentai Gorenjâ (1975)).
