The Armed Forces History Museum in Largo, FL has an extensive display of WWII and other era weapons from around the world, including Japan, in their Firearms and Ordnance Gallery.
Type 100 Sub-Machine Gun (1940) – Though slow in adopting a weapon they could use in jungle combat, the Japanese eventually developed the Type 100 sub-machine gun. Production on the Type 100 only lasted about three years, as it was never viewed as a successful weapon. It did, however, serve as a prototype for the future development of a similar weapon of a more simple design with a greater rate of fire (1944 model).
T-99 Machine Gun – Invented in 1939, the T-99 fed into the chamber from the top. Its design was based on an earlier machine gun – the T-96. Because of the backup in Japan’s war industry, the T-99 came forth too late, making little impact on the war. Still, it was a huge improvement over previous Japanese weapons.
T-11 Machine Gun – This light machine gun was the first one the Japanese invented themselves. It was an unusual gun and far from perfect. Like many of the Japanese machine guns, it was only capable of automatic fire.
Nambu Pistol – First produced in 1925, the purpose of this pistol was to supply the Japanese army with a cheap, easily-produced pistol. The major problem with this WWII weapon was, in order to remove the magazine, the gun had to be well-maintained and the individual’s hands had to be dry. This downfall is believed to have resulted in the death of many Japanese officers.
Type 94 Pistol – The Type 94 pistol was developed prior to WWII when the Japanese began seeking an even cheaper (than the Nambu) pistol. However, the Type 94 actually wound up being more expensive. First put into production in 1935, and despite being one of the worse pistols ever produced, close to 70,000 of them were produced.
Nambu Revolver – The first Nambu revolver dates back to 1893. Many of the features of this revolver were designed after western revolvers. Though well-built, this self-cocking revolver was incapable of single-action.
The Japanese were not known for the excellent craftsmanship of their weapons during WWII, which explains why this list of top machine guns and pistols, when reviewed, would at first glance might appear to be a list of their worst weapons.
