AKA: Tokyo Gore Police
IMDB

Tokyo Gore Police opens with a young girl being proud of her police officer father, only to witness him being murdered, which involves his head exploding. That's one of the tamer moments in this movie, which is an exercise in bad taste.
Ruka, the girl from the opening, has grown up and is now a police officer for the privatized police of Japan. She specializes in killing "engineers" (an genetically mutated killer who can regenerate their lost limbs and wounds into weapons). Her hunt for the man responsible for the mutations leads her to being implanted with the "engineer" key-shaped tumor.
The plot basically takes back seat to the over-the-top violence. Nearly every scene contains at least one geyser of blood raining down. In the final battle we see a man propel himself through the air using the jets of blood gushing from his severed legs.
There are many movies like this coming out of Japan lately. Machine Girl, which is a favorite of mine, is similar in violence, but offers more humor than Tokyo Gore Police. Not to say this movie is without humor. If you're going to portray this level of violence you better sprinkle in some humor or only psychopaths will watch your movie.
Some scenes in this movie, especially in the middle, could easily have been cut. There is a bondage scene that goes on for too long and is fairly irrelevant (although it leads to a man having a flesh wound penis that shoots bullets). I'm saying that my main problem with this movie (it's biggest flaw, if you will) is that it could have been cut down at least 10 minutes. Otherwise, it was a good effort in the genre of hyper-violent Japanese horror.
