Fujio (Tadanobu Asano) and Mitsuo (Sho Aikawa) spend their free time wrestling. Their boss interrupts one day and starts yelling at them. After an apparent heart attack, them dump him on the Black Fuji, a mountain of trash that contains everything - including bodies.
The chemicals in the mountain cause the dead to rise, and now Tokyo has some real problems.
You might think that writer/director Sakichi Satô would give us another Ichi the Killer, but you would be wrong. The blood is minimal. This is a comedy. There are a lot of people losing their heads, but no little gore.
The good thing is that they are real zombies, and you can outrun them.
After five years, Tokyo is completely zombified. Fujio is stuck with Yoko (Erika Okuda), a girl Mitsuo saved before he was bitten, and those that are not zombies are slaves for the rich.
Things do get really funny at the end, and a little crazy, too.
I just wish they wouldn't have repeatedly used the "R" word.
