Books related to Films By Studio Ghibli

Jannes: Hauru no Ugoku Shiro (2004) is based of the book, albeit with several significant changes.

Jannes: Panda! Go, Panda! 1(1972) is not a Ghibli film, but it's "proto-Ghibli" insofar as it's an early Miyazaki film that showcases a lot of what would become his trademark sensibilities. Panda! Go, Panda! started as an adaptation of Pippi Långstrump, but was scrapped and reworked when the creators failed to acquire the movie rights for the book.

Jannes: Gedo Senki (2006) is adapted from several books of the Earthsea series

Jannes: Kari-gurashi no Arietti (2010) is based on The Borrowers.

Jannes: Tenkū no Shiro Rapyuta (1986) loosely adapts some elements from this book, namely the floating city of Laputa.
