Kaguya
As a child, Takahata read "The Tale of the Bamboo Cutter". He recalled that he struggled to relate and sympathize with the protagonist; to him, the "heroine's transformation was enigmatic" and that it "didn't evoke any empathy from [him]". In 1960, Takahata was preparing for a potential adaptation for his employer Toei Animation, which eventually was abandoned. After rereading the tale, he realized the story's potential to be entertaining, as long as an adaptation allowed the audience to understand how Princess Kaguya felt.
