Rashomon is a 1950 Japanese film directed by Akira Kurosawa, working in close collaboration with cinematographer Kazuo Miyagawa. It stars Toshirō Mifune, Machiko Kyo and Masayuki Mori. The film is based on two stories by Ryūnosuke Akutagawa ("Rashomon" provides the setting, while "In a Grove" provides the characters and plot). Rashomon can be said to have introduced Kurosawa and Japanese cinema to Western audiences, and is considered one of his masterpieces.
The film has an unusual narrative structure that reflects the impossibility of obtaining the truth about an event when there are conflicting witness accounts. In English and other languages, 'Rashomon' has become a byword for any situation in which the truth of an event is difficult to verify due to the conflicting accounts of different witnesses. In psychology, the film has lent its name to the 'Rashomon effect'.
