Japanese Gun Law

I was reading what Wikipedia has to say about the Satsuma Rebellion (Seinan Sensou), which had a link to the Meiji Haitourei, and from there I jumped to the Japanese version, which had a link to information about the current Japanese weapons law (Teppou Toukenrui Shoji Tou Torishimarihou, established in 1958). Talk about a convoluted path.
