The World Masterpiece Theater entry for the year 1976, Marco, pushed studio Nippon Animation and the artists associated with it to their limits. As a result, the year 1977 was marked by disorganization, as most of Marco’s staff temporarily or definitively left the WMT, and the series for that year, Rascal the Raccoon, brought on new, possibly inexperienced, and simply less notable artists. This article will therefore not only focus on Rascal, but on two other works: the first is another Nippon show, Jacky the Bearcub, which counted among its staff most of Marco’s main artists: directors Isao Takahata and Seiji Okuda, and animators Toshiyasu Okada, Kôichi Murata, Reiko Okuyama and Yôichi Kotabe. The other is a completely different production, the first film by studio Shin-Ei, Tenguri, Boy of the Plains, which reunited Yasuo Otsuka and his students outside of Nippon Animation. Just a year before Future Boy Conan, 1977’s Rascal and Tenguri were the last works on which Hayao Miyazaki made significant contributions as a key animator. They therefore represent a turning point in his career, as well as that of all other artists who had been revolving around World Masterpiece Theater productions.
Yama Nezumi Rocky Chuck, known in the English-speaking world as Fables of the Green Forest, can be considered the first show to fit into the extended World Masterpiece Theater canon: it was the first production of studio Zuiyo Video, which would become Nippon Animation, to take place in the consecrated Sunday 19:30 time slot on Fuji TV.
