The weapons law begins by stating "No-one shall possess a fire-arm or fire-arms or a sword or swords", and very few exceptions are allowed.[30] The only types of firearms which a Japanese citizen may acquire is a rifle or shotgun. Sportsmen are permitted to possess rifles or shotguns for hunting and for skeet and trap shooting, but only after submitting to a lengthy licensing procedure.[32] Without a licence, a Japanese citizen may not even hold a gun in his or her hands.
And yet an armory exhibits fully automatic rifles intended for military use (unless those are airsoft guns). What the hell?
