Many countries have police officers that do not carry guns, but Japan is NOT one of them. They carry .38 special revolvers, not the high-capacity 9mm handguns often toted by the American police.[110] No officer would ever carry a second, smaller handgun as a back up, as many American police do. Policeman may not add individual touches, such as pearl handles or unusual holster, to dress up their gun. While American police are often required to carry guns while off-duty, and almost always granted the privilege if they wish (even when retired), Japanese police must always leave their guns at the station. Unlike in the United States, desk-bound police administrators, traffic police, most plainclothes detectives, and even the riot police do not carry guns.[111]
Instead of using guns, the police rely on their black belts in judo or their police sticks. Indeed, police recruit training spends 60 hours on firearms compared to 90 hours on judo, and another 90 on kendo (fencing with sticks). (The number of hours that Japanese police recruits do spend on firearms training is larger than what most of their American counterparts receive; that the Japanese are so thoroughly instructed in a weapon which they are expected to use in only the rarest of circumstances testifies to the highly cautious approach of the Japanese police towards firearms.) After police school, few officers show any interest in further firearms training, while continued judo and kendo practice is frequent. Annual police martial arts contests are important events. Sixty percent of officers rank in one of the top judo brackets. Beer bellies are non-existent. In contrast, many American policemen, if confronted with deadly assault, have no combat technique to use except gunfire.[112] The American police's heavy reliance on guns serves, intentionally or not, to legitimise a similar attitude in the rest of the population.
