How did the Japanese torture the civillains

The Japanese used very harsh methods to torture the civillains. They seemed to be happy seeing people in pain. They would use any methods to torture them, to fulfill their satisfaction. They certainly won't be merciful to anyone. These methods are rather disgusting. The most common way of torturing is physical beating. Followed by filling hot water or water into a person's mouth till the person pass out, and many other ways. In the past, these Japanese lust after womens. They would either rape or make those women their wife. So people in the past would avoid them whenever they are out, or stay at home most of the times.
