Who directed The Secret World of Arrietty?

The Secret World of Arrietty was directed by Hiromasa Yonebayashi.

The 2010 Studio Ghibli film marked Yonebayashi's feature directorial debut. Before directing, he had worked as an animator on major Ghibli productions including Spirited Away, Howl's Moving Castle, and Ponyo. Hayao Miyazaki served as the production planner, while the screenplay was written by Miyazaki and Keiko Niwa.

Arrietty adapts Mary Norton's 1952 children's novel The Borrowers, about a family of tiny people who secretly live inside a human home and borrow household objects to survive. The film follows Arrietty after she is discovered by Sho, a human boy, creating a cautious friendship between two inhabitants of radically different worlds.

The Japanese title is Arrietty, while The Secret World of Arrietty is the North American English title. This can cause confusion when searching for the film or its director. Yonebayashi later left Studio Ghibli and co-founded Studio Ponoc, where he directed When Marnie Was There at Ghibli and later Mary and the Witch's Flower at Ponoc.
