The Fuma Conspiracy sets itself up as a classic adventure movie, in search of a secret treasure, with a few rival factions to spice things up. This isn't too much different from the rest of the Original Green Jacket series, however the production certainly allows the movie to stand out.

Goemon is about to marry a woman called Murasaki Inabe, the daughter of a Samurai Clan with a hidden treasure and long held rivalry with the infamous Fuma Clan. The movie begins with the marriage ceremony being interrupted by the Fuma, and the adventure for our protagonists begins here. While Lupin III Part 1 is an excellent series, it is held down by poor audio-visual design, this makes The Fuma Conspiracy even better in this regard, as it perfectly captures the feel of Part 1 while making the movie look fantastic. The car chase scenes are animated fantastically while the beautiful art helps to create a sense of awe alongside the cool and silly nature of Lupin III. The OST was perhaps not as stand out as the rest of the design, though it served its purpose for the most part. Goemon's fight choreography was outstanding when he drew his blade, though this is largely expected from Lupin III at this point.

It's hard to find what to say about the plot in The Fuma Conspiracy. The issue is that it is very standard and is for the most part carried by a known cast. It feels like it could be any other episode of Lupin, just with very high production quality. Much of what it does is executed well, the exploration of the booby-trapped cave network felt like a scene from Indiana Jones, while the ending felt like the standard Tomb Raider conclusion. There's not much to praise for the narrative past being passable, which makes it seem somewhat shallow for me to say that I enjoyed it all the same anyway, likely just because it was a Lupin III movie. The generic nature of the story does not assist the movie however, therefore I was never truly impressed by what it was doing, because I'd seen it so many times before.

Ultimately "The Fuma Conspiracy" succeeded in being some nice fanservice for fans of the Lupin Green Jacket series but failed to truly stick out as a standalone movie. Such questions as "what was the 'conspiracy' exactly?" and "why are the Fuma even doing this?" dragged down the movie too much to become anything special, even if the production quality was fantastic.
