Detailed Photos: Hamada Pistols (7.65mm and 8mm)

IMG_8799

The Hamada pistols were two of the few examples of Japanese military arms made by private companies rather than government arsenals. Hamada ran a shop making sporting arms before the war (and after), and converted his production to a .32ACP blowback pistol of his own design for the military to use. It was a successful […]

The Japanese Type 93 and its slightly-improved sister the Type 100 were the standard flame weapons of the Imperial Japanese Army for its fighting in China and the Pacific. They are a smaller and handier design than the American weapons, and less user-friendly. The Type 100 uses a rotating valve to fire, paper incendiary […]

Japanese Type 4 Garand Photos

IMG_8293

Towards the end of WWII, in 1944, the Japanese Navy developed a copy of the American M1 Garand rifle, chambered for the 7.7mm cartridge.

The newly manufactured Japanese rifles were […]

The Japanese military was interested in finding a new self-loading rifle to adopt in the 1930s. The development project began with a request to retired General Kijiro Nambu who designed a gas-operate,d rotating bolt rifle but could not bring it up to the standards demanded by the military and opted to abandon the project […]

Screen Shot 2016-04-08 at 12.54.38 PM

Before the Type 14 Nambu pistol was developed to replace the “Papa” Nambu, Kijiro Nambu experimented with a high-capacity design with a 15-round magazine. This pistol was called the Type A Experimental, and was designed around 1920. Only 15 or 20 were made, and they show elements of both the Papa and the Type […]

RIA: Japanese 8mm Hamada Pistol

Just as production of the .32ACP Type Hamada pistols was reaching full scale, Bunji Hamada was asked to redesign his pistol to use the standard 8mm Nambu cartridge. This he did, and after several changes required by the Army (which appear to have had more to do with giving the Army some claim to […]

The Hamada was one of very few Japanese military weapons made by a private commercial firm. Designed and introduced in 1940, the basic Type Hamada pistol was a blowback .32ACP handgun similar in style to the Browning model 1910. About 5000 of them were manufactured during WWII, although most of these were sent to […]

The Type 100 (sometimes called the Type 0) was one of the initial Japanese experiments in paratroop rifles. Manufactured from standard Nagoya Arsenal Type 99 rifles, the Type 100 used a set of interrupted lugs at the chamber to allow the rifle to be broken into two short sections. Only a few hundred of […]

This rifle is one of the third iteration of the design from Nippon Special Steel. It is a design based originally […]

Partway through 1944, the Japanese Imperial Navy began a program to provide their infantry units with better firepower than was afforded by the bolt action Arisaka rifles. The initial experimentation was based on rechambering captured US M1 Garand rifles for the 7.7 Japanese cartridge, but an incompatibility of American en bloc clips with the Japanese […]
