By 1945, Japan's industries were crumbling and like the Germans the Japanese tried to both field more advanced weapons while also developing primitive arms for civilian paramilitary forces. In preparation for the home island invasion Japan was busy with jet aircraft, missiles, microwave weapons, midget subs, submarine carriers, and an atomic program in occupied Korea at Konan. The Germans shipped them advanced components and blueprints via U-boat. But progress was slow. The Heerswaffenamt sent primitive weapons documents as well. Japan made a Type I Rifle of standard 7.7mm of low grade steel and unfinished wood furniture which was a breech-loader single shot with bent metal trigger and guard, simple sights. The following Type II Rifles in 8mm were cruder block types with slider rails for recoil. Last were percussion arm National Civilian Rifle and Pistol using Black powder!!! The Rifle had a smoothbore pipe for a barrel in 13mm and fired a 15mm steel rod projectile using 5 grams of powder set off by a hammer striking a cap over a flash hole on top of the barrel. Pistol of unknown caliber used same action. See below...
