Butcher Block is a weekly series celebrating horror’s most extreme films and the minds behind them. Dedicated to graphic gore and splatter, each week will explore the dark, the disturbed, and the depraved in horror, and the blood and guts involved. For the films that use special effects of gore as an art form, and the fans that revel in the carnage, this series is for you.

Even with the word “gore” in the title, it still doesn’t begin to touch upon the sheer volume of blood spray, viscera, and body horror in Tokyo Gore Police, a satirical horror comedy from Japan. Nor does it even hint at the complete insanity the film contains. It’s a simple tale of revenge at the center of absolute madness; young police officer Ruka is determined to track down her father’s killer. The catch is that she must hack and slash her way through mutant rebels called Engineers. What’s an Engineer? A breed of tumor infested mutant humans who can turn an injury into a weapon.

Think cutting off an arm and a toothy, razor sharped mouth grows in its place. Or perhaps an Engineer might lose his, uh, member, and a rifle pops up where the stump was. The ability to regrow parts with deadly weapons makes the psychotic Engineers even more lethal. The only way to destroy them is to sever a key-shaped part from their body. Naturally, this is a difficult and bloody affair. As such, society is reliant on the specialized police force issued with machine guns and swords to protect them from the Engineers. Yoshihiro Nishimura weaves in conspiracies and social satire with the over the top gore. Add one part Robocop, one part David Cronenberg body horror, and two parts excessive splatter and you have Tokyo Gore Police.

Fans of Japanese horror will recognize the lead actress portraying protagonist Ruka; Eihi Shiina previously terrified audiences as the unhinged Asami in Takashi Miike’s Audition. Playing her role straight, Shiina’s character gives the story more emotional depth than expected in a splatter film of this type. It’s sometimes perverse, sometimes zany, and sometimes even tragic, but all of it completely soaked in blood. Yoshihiro Nishimura makes a cameo in his own film, but eagle-eyed viewers should also look for notable Japanese splatter/shock director Sion Sono (Suicide Club, Cold Fish, Tag) in a cameo part as well.

Director and co-writer Yoshihiro Nishimura has an extensive background in special effects and makeup effects. He’s been dubbed the “Tom Savini of Japan,” and handled the gore effects for Japanese splatter films Meatball Machine and The Machine Girl. It was his work on the latter that directly lead to Tokyo Gore Police, with the director using his earlier short film Anatomia Extinction as the basis for the story. In addition to directing and editing, both consuming tasks on their own, Yoshihiro Nishimura also supervised the special makeup effects and handled some of the mold making. His first commercial film, Yoshijiro Nishimura was given free rein to go nuts. His scale for the bizarre, perverse, and violent is on a much bigger playing field than most, which means Tokyo Gore Police is a different breed of splatter that won’t be for everyone.

With an extensive background in special makeup effects and names like David Lynch, Salvador Dali, and Alejandro Jodorowsky as major influences, Yoshijiro Nishimura’s first major film is difficult to classify. Ruka is a strong heroine out for vengeance, but the plot really is far more convoluted than that. It’s a Lynch style fever dream narrative by way of cartoonish violence and humor. Yoshijiro Nishimura wasn’t interested in realism, he wanted something that was fun for the audience. Tokyo Gore Police is a cult film in every sense, and one of the bloodiest films in existence.
