Nihon Review's Shinmaru writes: "Miyazaki Hayao has had an illustrious career. Any anime fan could name several of Miyazaki‘s films off the top of their head. Every career must start somewhere, however, and Future Boy Conan is one of the most important stepping stones on Miyazaki‘s path as a director. Nearly every Miyazaki trademark is present here: the character designs, the whimsy, the aircraft, the sense of fun and adventure, the environmentalism, etc. This is the prototypical Miyazaki work — an example of a great creator making his mark at a time just before he perfectly honed his craft."
