The two Patlabor movies directed by Mamoru Oshii are landmarks in anime history. Even without considering their intrinsic artistic qualities, their importance for the development of the aesthetics and techniques of Japanese animation cannot be overstated. Major works in the post-Akira landscape, they played a key role in the maturation of realist animation and contributed to introduce capital players such as studio Production IG, director Satoshi Kon, or animators Kazuchika Kise and Hiroyuki Okiura. And that is not all, as they were also central for the development of 3DCG animation and the spread of the modern layout system, which thoroughly changed animation craft. In other words, they are essential works in order to understand Japanese animation of the last 30 years.
The “realist” aesthetic and approach of the show was possible thanks to its director, who in fact debuted as chief director: the second of the three Yoshida brothers, Ippei Kuri. Largely overshadowed by the other two rising anime directors of the time that were Isao Takahata (in Tôei) and Osamu Dezaki (in Mushi), Kuri was easily on par with them in terms of artistic vision; one may even argue that him and Tatsunoko’s artists and technicians largely laid the ground that would make Dezaki’s expressionist style possible. In that regard, Sanshirô can be read as a site for formal and technical experimentation, wherein “realism” was but one of the many aspects that were explored.
