Katsuya Matsumura's 1995 horror movie "Concrete-Encased High School Girl Murder Case" is based on a true crime case of Japanese schoolgirl Junko Furuta.In November of 1988 four young men abducted and held Furuta for several weeks in the house of one of the captors.The girl was violently raped and subjected to torture and sexual degradation for example she was forced to masturbate.On 4th January 1989 four sadists beat her with an iron barbell,poured lighter fluid on her legs,arms,face and stomach and immolated her.She died later that day of shock and her mutilated corpse was hidden in an oil-drum filled with cement.Katsuya Matsumura of "All Night Long" series fame is possibly the most misanthropic Japanese film-maker."Concrete-Encased High School Girl Murder Case" is an incredibly nihilistic and disturbing film loaded with scenes of sexual violence and abuse.This is an ugly and honest piece of Japanese exploitation that tells about man's barbarity and willing to torture,dominate and exploit the weaker.I can't wait to see Matsumura's newest horror film "Ki-re-i?".Watch this one at your own risk!
