Disguised as a lumber mill 
But the "logs" was cut with a knife 
The Doctors are trained to kill 
So ends another life 

Experiments in terror 
Vivisection on living tissue 
Blame it on the Human error 
But that's not the issue 

Unit 731 
The men behind the sun 
The devil dressed in white 
Day has turned to night 

Weapons of different kind 
Exposed with such ferocity 
The blind shall lead the blind 
The never-ending atrocity 

Unit 731 
The men behind the sun 
The devil dressed in white 
Day has turned to night 

History is repeating day after day 
Oh, when will we ever learn? 
Perpetrators they just walk away 
In purgatory they will burn 
They will burn! 
You will burn! 
Burn! 

Weapons of different kind 
Exposed with such ferocity 
The blind shall lead the blind 
The never-ending atrocity 

Unit 731 
The men behind the sun 
The devil dressed in white 
Day has turned to night
