Red Room (赤い密室(へや) 禁断の王様ゲーム, Akai misshitsu (heya): Kindan no ōsama gēmu) is a 1999 Japanese V-cinema (direct-to-video) horror film written and directed by Daisuke Yamanouchi.

[1] The film follows a group of four contestants (a husband and wife on the verge of divorce, a young corporate woman, and a 17-year-old schoolgirl) on a reality TV game show who are locked in the titular "Red Room" to torture each other, with the last person standing winning ten million yen.

The tortures chosen start off relatively mild, but gradually escalate into extreme sadism and sexual abuse.

The film was originally released in Japan in VHS format on June 4, 1999[1][2] and later as a DVD on December 22, 2005.

[3] Red Room was released in the US by Anthem Pictures on January 9, 2007.
