Yeah I know, was mostly joking.Sorry to deflate your weeb boner, but guns are virtually impossible to get in Japan now. You're limited to air rifles and single shot shotguns (the later for hunters only). And even those require jumping through a shit ton of hoops. The precious few remaining hunting rifles in private ownership have to be turned in when the owner dies, never to be resold. No new rimfire (that means your waifu with the Ruger 10/22) or centerfire rifles are sold anymore, and I don't think handguns ever were.
Oh sure, the occasional beating and stabbing will happen, but even the Yakuza find guns to be more trouble than they're worth. The cops carry 5 shot .38 snub-nosed revolvers, and rarely employ them.
The day "Yuko-chan" struts down Akihabara mowing down salarymen and otaku with a semi-automatic rifle is the day I'll fly to Europe and personally suck Null's cock.
But I also said East Asia which includes South and North Korea, Taiwan, HK, Macau, China and Mongolia if you count it as East Asia. Although I bet those countries have gun laws as strict as Japan.
