Princess Mononoke is a period drama set in the late Muromachi period of Japan but with numerous fantastical elements. The story concentrates on involvement of the outsider Ashitaka in the struggle between the supernatural guardians of a forest and the humans of the Iron Town who consume its resources. There can be no clear victory, and the hope is that relationship between humans and nature can be cyclical.
“Mononoke” (物の怪) is not a name, but a general term in the Japanese language for a spirit or monster. The film was first released in Japan on July 12, 1997, and in the United States on October 29, 1999.
