Yes and Japan is notoriously homogenized. Perhaps they do not have a gun problem because they do not have a pavement ape problem that other questionable countries you mentioned have.

Almost as if there is one characteristic that links all these nations together. In fact, one nation got rid of guns and then proceeded to witness a surge in knife crime. And there was also a point in time where Sweden or some other conquered nation had routine grenade attacks. Odd that no one called for common sense grenade legislation then. They did criminalize anyone who had a knife, including chefs. But yet that did not stop knife crime in much the same way gun laws do not stop gun crime especially in a nation infested by savages.
