Pink film

Pink film is a type of adult movie that originated in Japan in the 1960s. Usually, these movies involve adult content, such as nudity or sexuality, and are intended for mature audiences. Even though they are usually considered pornography, they are not as explicit as Western adult movies.

The term "pink" comes from the color of the film stock used to shoot these movies. Back in the day, the studios producing them did not have a lot of money, so they had to use a cheaper type of film stock. This sort of film stock had a pinkish hue, which gave these movies their name.

Pink films are usually quite short, lasting around 60-90 minutes, and have lower production values than mainstream movies. Often, they are shot in just a few days, with a limited budget and small crew.

Despite their low production values and limited budget, pink films became extremely popular in Japan, and their influence spread to other countries, such as Hong Kong and Korea. Today, pink films are still being made in Japan, although they have evolved to include more diverse themes and genres beyond just adult content.

In summary, pink film is a type of adult movie from Japan that became popular in the 1960s. They are usually short, have low production values, and feature adult content, but are not as explicit as Western adult movies.
