You think a lot of people can figure out how to build their own guns and ammunition from raw materials? The shooter in this case used some metal pipes from a hardware store, a piece of wood, some duct tape, and an electrical igniter he made himself. He had to make his own ammunition and gunpowder from raw materials too. Moreover, the guy wasn't some random idiot; he was in the army before and had some kind of technical job there. As for "moving around Japan", in case you've never looked at a map, Japan is an island (or more properly, an archipelago). You can't just import guns there. And buying a gun is very difficult and will put you on a first-name basis with the local cops, and even here all you can buy is a hunting rifle or shotgun, and you better have a good reason to own it. Handguns are completely prohibited. The idea that some criminal could just show up in town, heavily armed, is utter fantasy.
