The Japanese figured out in the 1930's that the 6.5mm round was not lethal enough, and that
a new cartridge was needed. In 1932, the 7.7mm cartridge was developed, and it was the ideal
round for the Type 99 rifle. This rifle, introduced in 1939, was just a re-chambered version of the
38th year rifle. This weapon held 5 rounds total, and weighed 9 pounds. This weapon was also fitted
with special sights, for air attack. The idea was that a soldier could sight in on an incoming
airplane and hit it. This rifle was shorter than the normal Arisaka.
For a while, the Arisaka was the standard issure rifle for the
Japanese infantry man. It also carried five, 6.5 X 50SR Arisaka rounds. The Arisaka is also commonly
known as the '30th Year Rifle'. It weighed 9.5 pound empty, and was rather long at 50.25 inches, taller
than the average Japanese soldier. This rifle had an odd safety. On the back of the bolt was a knob, that
pushed in a turned, would activate the safety mechanism. Arisaka gained it's name after it's inventor,
Colonel Arisaka. The type 30 is named that way because it was designed in the 30th year of the Meiji
Restoration, which means it was designed in 1897. This weapon also comes in Long Rifle and Carbine

Even though the submachine gun is an ideal weapon for jungle combat, the Japanese
did not adopt oneuntil 1940. The Type 100/40 used the 8 X 21.5mm Nambu round,
and weighed 8.5 lbs. unloaded.It's magazine was curved and located on the left side
of the gun. In 1944, the Japanese simplifiedthis gun, and came up with the Type 100/44,
which was changed because it was easier to produce.The Type 100/44 had a detachable
Despite the fact that most of the Japanese theater was
jungle warfare, the Japanese were very slow to build or adopt a weapon suitable for jungle
combat. Eventually, they came up with the Type 100 Sub-Machine Gun. The Type 100 lacked power,
as it used the small 8mm pistol round. This weapon was about 8.5 pounds, and carried 30 rounds.
It wasn't a very successful weapon overall. Not many were made, as production only lasted about three
years. In 1944, one year after production ceased, an improved model was made. It wasn't as time
consuming to make, as it was built off a more simple design, such as welding and fixed sights. It also
had a greater rate of fire than the older 1940 model.
The T-99 Machine Gun was invented in 1939,
specifically designed to fit the 7.7m rimless cartridge. It weighed in at about
23 pounds empty, and had a 30 round detachable magazine on the top of the
weapon, which had better feed into the chamber, with the help of gravity. The
T-99 was based off the earlier T-96, fairly new at the time, and was a great
improvement. The newer cartidge was also better, now that it didn't need to
be oiled, and fixed a few jamming problems that earlier weapons had. The
weapon was good, but came to late to make a considerable impact. The war
industry in Japan was backed up, and never got to meet the demand for this
particular weapon. The T-99 was fitted with a monopod so the stock, but it
proved to be almost totally useless. Overall, this gun was much of an improvement
over the past weapons that the Japanese had. It had more powerful ammunition,
and unlike many other Japanese weapons, not many jamming problems. Like most
Japanese machine guns, it was only capable of automatic fire.
The T-11 (Taisho 11th year) was
the first light machine gun that the Japanese had invented themselves.
It was a very unusual gun, and wasn't usually perfect. It was different from
any other machine gun of the time. It used the normal 6.5mm cartridge,
and weighed about 22.5 pounds empty. The way the gun was feed ammunition
was very different. There was a hopper on the left side of the weapon, which
held 5 normal Japanese stripper clips of 5 rounds each, which held all together
30 rounds. This means that any normal Japanese rifleman could contribute
ammunition to the machine gun crew if they were in need of ammunition. This
complicated system lead to many jamming problems. Also, the 6.5mm round, with-
out lubrication, was difficult for the gun to extract. There was a specially loaded
round, that was somewhat less powerful than the normal 6.5mm, but prevented
case rupture. The T-11 was capable of only automatic fire.
Invented in 1925, the Nambu pistol
was made so the Japanese army would have a cheap, and easilyproduced
pistol. The Nambu carried eight 8 X 21.5mm Nambu rounds, and weighed
2lbs.unloaded. Later, in 1939, the trigger guard was enlarged, so it could be
fired while wearing gloves.A problem with the Nambu was that the magazine
could only be removed sucessfully if the gun had good matinence, and if the
firer's hands were dry. This resulted in many deaths of Japanese officers.
After the design of the Nambu
in 1925, which was designed to be cheap, the Japanese army was looking to go
even cheaper. What they came up with was actually more expensive. Despite this,
the Type 94 was put into production in 1935.The Type 94 weighed 1.5 lbs. unloaded,
and carried eight 8 X 21.5mm Nambu rounds. The Nambu is most likely one of the world's
worst pistols ever manufactured. The most serious problem of the whole pistol was the
exposed sear. If enough pressure was put on the sear, the gun would fire. Towards the
end of the war, the quality of these guns got even worse. A total of 70,000 Type 94's
This weapon was created in 1893, and it's design
taken from many western revolvers. Some parts are from Smith & Wesson models, while
others are European. It was also highly based of of the Russian Nagant. It was a fairly
well built revolver, but little more. It was a self-cocking revolver, incapable of single-action.
It carried six, 9 X 22R Japanese rounds, and weighed almost 2 pounds empy.
The type 97 was odd in the sense that it was a fully automatic anti-tank rifle. It held seven
20 X 124mm rounds.It was the heaviest of all anti-tank rifles, weighing 152 lbs. unloaded.
In order to help get rid of thefearsome recoil, the barrel and reciever slided in the stock.
To help support the gun's emense weight, the gun had a bipod in the front, and a monopod
towards the rear, which was dug rearwards into the ground to absorb some of the recoil.
The Type 97 required a four man crew for firing, which made moving and operating it
easier. Another attempt to reduce the recoil was adding a muzzle break.The Type 97 fired
solid armor piercing shot, and high explosive rounds. The Type 97 was alsoused as an anti-
aircraft gun by the Japanese navy.
