During Hiromasa Yonebayashi's time at Ghibli, he directed two films, "The Secret World of Arietty" and "When Marnie Was There." After “Marnie” in 2014 and with the studio heads either retired or about to be, Yonebayashi realized that he could no longer fulfill his ambitions at the studio, so he quit and founded Studio Ponoc with producer Yoshiaki Nishimura.
