The film is dedicated to Monkey Punch, the creator of Lupin III, who died in April 2019, six months before the film released.
Bringing Lupin III into the 3D format was one of Monkey Punch's most cherished goals, and before his passing he was able to see a preview of the film's footage during post-production. When Monkey Punch saw the footage he stated: "I've been looking forward to a 3DCG Lupin III for a long time. I've taken a look at the characters and story: it looks like this Lupin will come packed with new sensations, and I'm getting excited just thinking about how the film will turn out."
Takashi Yamazaki cites Lupin III: The Castle of Cagliostro (1979) as an influence on the film, describing it as one of his favorite films.
The filmmakers studied French and Belgian comics, and brought in French animators, to get the right atmosphere for the France-set scenes.
Marza Animation made over 12 screenplays and 3 story reels for the film.
