The Great Yokai War (妖怪大戦争 Yōkai Daisensō?) is a 2005 Japanese fantasy children's film directed by Takashi Miike and produced by Kadokawa Pictures. In the 2005 Toronto International Film Festival and on its June 30, 2006, American premiere, in New York City, it was released under the international English title The Great Yokai War by Tokyo Shock.
The Toronto festival site defines Yokai as "bizarre-looking monsters and supernatural beings from Japanese folklore who like to play tricks on unsuspecting humans". Daisensō literally means "great war".
It borrows the title of a 1968 film, which was released in the US by ADV Films as Yokai Monsters: Spook Warfare, part of the Yokai Monsters series and directed by Yoshiyuki Kuroda. Whereas the original used tokusatsu special effects, the 2005 version makes heavy use of stop-motion puppet animation and CGI.
