The Film Classification and Rating Organization , also known as Eirin (映倫), is Japan's self-regulatory film regulator. Eirin was established on the model of the then-Motion Picture Association of America's Production Code Administration in June 1949, succeeding the US-led occupation authorities' role of film censorship during the Occupation of Japan. It classifies films into one of four categories depending on their suitability for viewing by minors of different ages.
