This project follows Operation Jet Jaguar (2023), both as the next short in the "Godzilla Fest" series and chronologically. The online video celebrates both the anniversary of Godzilla (1954) and Ghidorah, the Three-Headed Monster (1964), marking the 60th anniversary of the latter.
The full title for this short is Fest Godzilla 5: The Great Battle of the Monsters (フェス・ゴジラ5 怪獣大決戦). It marks the fifth installment created for "Godzilla Day," following Operation Jet Jaguar (2023) which was the fourth entry. All five shorts were directed by Kazuhiro Nakagawa.
The Japanese title of the short, 怪獣大決戦 (Kaiju Daikessen), can be translated in several ways. However, Toho released a blog post providing the official English translation as The Great Battle of the Monsters. This contrasts with the title used in the English subtitles at the end of Operation Jet Jaguar, which translated it as "All Monsters Showdown" at the time.
Suit actors for the short were Naoya Matsumoto as Godzilla, Naoya Iguchi as King Ghidorah and Kenya Saito as Jet Jaguar.
The indoor set, built on Stage 9 at the Toho Studios lot, was used for filming that took place over the course of just four days. Noted on the Godzilla Store.
