This slice of powerful eastern erotica takes place over one day in a house of pleasure in 1950's Tokyo on the eve of a new law which will ban prostitution. With an observant and perceptive eye, director Kumashiro depicts the sometimes sad, sometimes funny but always highly engaging lives of the girls who work on this "street of joy". This is one of the most successful of Nikkotsu's famous "romantic porno" movies. Many critics consider it amongst the best Japanese films of the 1970s.
