Anatahan (アナタハン), also known by its on-screen title of The Saga of Anatahan, is a 1953 black-and-white Japanese war drama film directed by Josef von Sternberg, with special effects by Eiji Tsuburaya. It was adapted by Sternberg from Michiro Maruyama's nonfiction account of the seven years he and a group of World War II Japanese holdouts spent on Anatahan island, which was then part of the South Seas Mandate of Imperial Japan and is now one of the Northern Mariana Islands of the United States. This story also inspired the 1998 Japanese novel Cage on the Sea.
