Without any aim to be comprehensive, this article will follow these developments and focus on two shows: 1974’s Hurricane Polymar and 1976’s Gowapper 5 Godam. Although very different, both works are good examples of Tatsunoko’s development in the middle of the 70s: in terms of staff, the studio increasingly opened itself to the rest of the industry, but in terms of inventivity, it was rather closing. This contributed to the formation of an instantly-recognizable Tatsunoko aesthetic and brand, but also entailed a diminishing creativity, further decreased by the series of exodus that went on in those years.
If one single work were to sum up Tatsunoko’s entire production, it would probably be Science Ninja Team Gatchaman. By far the studio’s most iconic series, it was already one of its most popular when it came out. It started airing in 1972, 10 years after the creation of the studio, and 5 years before the death of its creator and leader, Tatsuo Yoshida. Due to this special position, Gatchaman easily stands as an exceptional high point in Tatsunoko’s early history. Moreover, because of its length (105 episodes!) and the changes that occurred within Tatsunoko during its production, it symbolizes the end of an era for the studio: it is, in a sense, the last work from its “early years”. Indeed, it would be so hard to replicate Gatchaman’s success that most of Tatsunoko’s following works are more-or-less simple copies or parodies of it. It would not be until Yoshida’s death and the production of a new Gatchaman series, in 1978, that the studio would find again the creativity and originality of its first years.
