Nambu World: Arisaka Type 2 Paratroop Rifle

The Model/Type markings are generally found on the top of the receiver, forward (towards to muzzle) of the chamber and generally indicate original caliber unless modified by another country at a later date. The serial number is found on the left side of the receiver on most standard rifles. The Arsenal mark on Japanese rifles is generally found to the right of the serial number on the left. Feb 29, 2016 This video shows the various stages of the Type 99 Arisaka, the main Japanese battle rifle of World War II, and some of the things to look for when buying one. Picked up a Arisaka Type 99 rifle yesterday. Serial number is 274XX ( obviously those XX are really numbers but i dont want to list the entire serial number here ). Aug 12, 2018 Here is a photo of an early Type 99, a 31st series Toyo Kogyo Type 99 made in 1940 (on top) compared to a 7th Series Nagoya late war rifle made in 1944.

The Type 2 Paratroop rifle is basically a take-down version of the Type 99 Arisaka rifle. It fires the 7.7mm X 58 Arisaka cartridge. The Japanese experimented with several versions of paratroop rifles, including ones with folding stocks and an interrupted thread-style take-down before settling on this one, which has a screw-in wedge that holds the two halves together (the system will be described in great detail below with close-up photos). The Type 2 is the only paratroop rifle that was produced in any real quantity (i.e. more than a few hundred), and even it is rare, with only about 21,200 known to have been produced. The model designation comes from the year based on the Japanese system that counted from the date of the mythological founding of the Japanese Empire by Emperor Jimmu in 660 B.C. By this system, the Western year 1942 when the gun was adopted was 2602, with the 'two' becoming the model designation. Actual production began in late 1943. I was very lucky to acquire this rifle in late 2008 from the daughter of the U.S. veteran who brought it back. It came with the 'bring back' document and a few other items that he brought back. These are shown further down the page together with a brief summary of the soldier's story. The gun is all matching, and although the 'mum' has been ground, it appears to be in unissued condition. Immediately below is a view of the left side. Overall length is 1120mm(44-1/8'). The barrel is 649mm (25-1/16') when measured as required by Canadian law (rod down the barrel with the bolt closed).

The Japanese did not make very extensive use of paratroopers and development of specialized weapons for them also lagged. According to the Fred Honeycutt book Military Rifles of Japan, (pp. 134-135), the experiences of the airborne attack on Palembang in Sumatra, Dutch East Indies, February 13-15, 1942 may have provided the impetus for the Japanese to get serious about paratroop weapons. In that battle, the airborne troops were equipped with standard rifles that were dropped in separate canisters and ended up landing in swamps some distance from the men, who then had to fight with just pistols, bayonets and grenades. The exploits of this intrepid, if unlucky, unit were immortalized in a dramatic painting by Goro Tsuruta (1890-1969; Tsuruta is the surname). For more on Mr. Tsuruta, see Goro Tsuruta | IFPDA). This image appeared in a magazine and also on postcards. Here is the postcard version. The caption on the left says 'Paratroopers landing in Palembang. Army sent to Sumatra region. Goro Tsuruta. With the permission of the Ministry of the Army.' The back says 'Issued by the Army Museum Association'.

Now I know you are dying to see how the gun comes apart, so here is a teaser: right and left shots of the gun in two pieces. In the first one you will note a screw with a D-ring through it at the front of the bottom (rear) half. Turning that is what loosens the wedge so the gun can come apart. But more on that later.

Let's start our detailed tour with the markings. Here is the top of the receiver. As noted above, the Imperial chrysanthemum, usually shortened by collectors to the 'mum', has been ground off, but you can still see some around the edges. The grinding of the mums was reportedly done to spare the Emperor the embarrassment of having his symbol fall into enemy hands (actually the Japanese always either cancelled the mum or ground it off on weapons that were withdrawn from active service in the Imperial Army or Imperial Navy, even when they were sent to allies or to other departments of the Japanese government). Below that are two kanji characters, ni-shiki, or 'Type 2'. The hole below that is a vent hole for gases to escape in the event of a case rupture. All Japanese rifles had this feature. The earlier Type 38s had two holes; when the Type 99 was introduced, they decided one would do (the Type 2 is a derivative of the Type 99).

The serial number, 16776, is on the left side of the receiver. Since total production was a little over 22,000, this one was made about 3./4 of the way through the production run. The mark after the number is the Nagoya Arsenal logo. Nagoya was the only arsenal to make these rifles. The small square in the upper right of the photo is actually a partially struck kanji character na (as in Nagoya), which was used by Nagoya Arsenal as an inspection mark.

The two halves and the barrel are also marked on the left side with an assembly number, in this case 775. This number bears no relation to the serial number; it is only a coincidence that it is so close in this case.

OK, so how do you get it apart, and what holds it together? At the far right of this photo you can see a round knob with a D-ring through it. That is the knob that you have to undo to take it apart. A couple of turns counterclockwise will do it. Then the wedge that holds the two halves together slides out to the right. If it is stuck and WD-40 or something similar won't loosen it, then you may have to undertake drastic measures. This one was completely jammed when I got it, but I think I did more than necessary to get it apart. I removed the sheet metal protective guard and the D-ring and then wrapped the knob in cloth and used a pair of pliers to get enough torque on it to turn it. I probably could have just removed the D-ring and left the protective sheet metal guard in place. Live and learn.

Here is the connecting part of the front half. Note the indexing hole to the right of the photo (it's below the barrel when the gun is oriented normally instead of being on its side). There is a peg on the front part of the rear half that fits in that hole to line things up. Now, take a look at the bottom of the barrel. See that notch? That's what the wedge fits into to hold the two halves together. The next photo shows it from a better angle.

In this photo taken from the right side you can see the notch very clearly. In the photo it is just below the flat metal surface that has that indexing hole in it.

Here is the wedge in the 'out' position. You can also see the sheet metal guard that surrounds this whole area and is held on by a screw that you see just above and to the right of the wedge. At the extreme right of the photo you can also see part of the peg that fits into that indexing hole on the front half.

This photo shows the groove in which the wedge travels. You can also see the indexing peg at the bottom.

Here the peg is half-way across the groove in which it travels. That indexing peg is again at the bottom of the photo.

Now let's take a tour from the muzzle to the butt of the rifle. Daisy reader for mac. You can see here that the front sight is protected by metal ears. The tip of the cleaning rod is also visiible, and at the very bottom, the stud for fixing the bayonet.

Here's a close-up of the ears and the front sight.

On the bottom you can see that the bayonet stud is marked with the last three digits of the rifle's serial number, 776. That little square button at the far left is the cleaning rod release.

Here;s the cleaning rod, which is 541 mm (21-5/16') long.

Here's the interesting part that sticks out the front when it is in place on the gun. This includes the slot for cleaning patches at the far right and the recessed segment for the cleaning rod retaining spring at the far left.

The other end is threaded. This is not for screwing into the gun (a spring retains the rod), but rather for attaching accessories like a cleaning brush.

Here;s a close-up of the recessed segment that the retaining spring fits into.

The rear sight is graduated to 1500 metres. Note the AA (anti-aircraft) wings. These were deleted on later specimens, with the switchover occurring gradually between around serial 14000 and 18000.

Here are those wings in action. The idea of having riflemen shooting at planes was taken seriously enough that I have many period photos showing groups of soldiers practicing doing so. As far as I can determine, nobody thought that a single guy with a rifle was going to shoot down a B-29. However, a large group of 50 or more soldiers all shooting in volleys at a low-flying plane might be enough to dissuade a pilot from swooping in to strafe the group, I suppose.

This top view of the rear sight shows the numbers better. The numbers on the wings were supposed to correspond to the speed of the aircraft in hundreds of kilometers per hour. Obviously the faster the plane, the more the shooter had to lead the plane to have any chance of hitting it.

There is also a peep sight for quick aiming at normal battlefield distances.

Here is a shot of the top of the rifle.

This is a shot of the bottom of the gun. Note the whole in the bottom of the stock at the far right, just forward of the area where the two halves join. This was to drain water out of the stock if it got wet so the water would not get trapped there and rust the barrel.

Just to the rear of the lower tang is a stock inspection mark. It is applied so that to be read properly the gun should be held muzzle up.

Here is the mark rotated into the proper orientation. It is the kanji na, as in Nagoya, and was a standard inspection mark of Nagoya Arsenal.

Now let's take a look at the action. Here's the right side.

Top view. Note the plum shaped knob on the bolt handle and the Mauser-style bolt release (upper left of photo). You can also see where the stripper clip of ammo would fit in (the front of the bridge just ahead of the bolt handle).

Arisaka type 30 parts

The safety was still made with the elaborate radial checkering. The notch is the position indicator. The safety is off in this photo.

Here are two shots of the safety. On the left the safety is in the off ('fire') position, while on the right the safety is in the 'on' ('safe') position. Note the positions of the indicator notches; straight up is the 'safe' position. HOWEVER YOU SHOULD NEVER RELY ON THE SAFETY ON ANY FIREARM. ALWAYS TREAT THE GUN AS IF IT WERE LOADED AND READY TO FIRE! If you have a matching Arisaka, the safety will probably go into the on and off positions fairly readily. However, if the gun is not matching, you may have a lot more trouble and it may not go into the safe position at all. This is because the guns were made with a lot of hand fitting and so the lug a non-matching safety may just not fit into the appropriate notch. This one matches and so the safety works easily. A lot of people think Arisaka safeties are way too stiff, but this is usually because they are not operating them correctly. Engaging the safety requires compressing the firing pin spring, which is quite powerful. So the trick is to use the heel of your hand, not your finger tips. Hold the gun by the small of the stock in your left hand and use the heel of your right hand (the lower part of the palm near the wrist) to twist it on and off. That way you are using the strength of your arm, not just your fingers. Easy once you know how.

Here's a top view of the 'off' (left) and 'on' (right) safety positions.

Here is how the bolt release opens. Just pull the front of the lever outwards.

Here is a rear view with the bolt removed.

The bolt, right side as it comes out of the gun with handle upwards. That flat piece running along the side is the extractor.

In this close-up you can see the serial number on the bolt handle and extractor.

Here's the left side as it comes out of the gun.

A bottom view.

Edem software download. To strip the bolt, just give the safety knob a quarter turn. It comes off and the rest of the parts slide out. This photo shows the extractor (top), bolt body (centre), safety (lower left), firing pin (lower right) and firing pin spring (bottom right).

The other side of the same parts.

In this close-up of the trigger guard you can see the magazine floor plate release just in front of the trigger (right of the trigger in the photo).

Pulling backwards on the release allows the magazine floor plate, spring and follower to swing downwards. The mag holds five rounds.

This shot shows the hinge mechanism.

The bottom of the forestock shows this insert. It would have been put in when the gun was made to deal with an imperfection in the wood such as a knot.

Although the gun shows essentially no wear and appears unissued, 60 plus years of travels and storage take their toll. It has the usual small scratches and dings, some light rust in a couple of spots and on the left side, this strange discoloration of the wood, which appears to be a burn of some kind.

On the right side of the action there is also this strange group of scratches. Given their long, continuous, back-and-forth pattern, I suspect this happened during shipment at some point, when it rattled up and down against something sharp and hard like a staple.

There is a groove in the stock above the rear sling swivel that appears to be there to allow for clearance for a hook type attachment.

The butt plate is what collectors call the 'cupped' design.

This is the 'bring-back' document for this rifle. US servicemen required such a letter to authorize them to bring back war trophies. This one was made out to Sgt. Chester D. Stripling and signed by Infantry Captain Owen W. Skreen. It bears the seal of the 387th Infantry Regiment. From Sgt. Stripling's daughter I learned that his ship was headed for the Pacific Theatre, but when Japan surrendered he ended up in Tokyo. He acquired the rifle while serving in the early part of the US Occupation of Japan. I have a separate letter from her attesting that this document was issued in connection with this rifle, since the document itself does not include a serial number (many did not).

The bottom half of the document just repeats the information on the upper half, so let's zoom in on the upper half so it is easier to read.

Bayonets for the Type 2 Paratroop Rifle

The Type 2 takes a standard Type 30 bayonet, and photos suggest that is what it was most often used with. Given that these rifles were produced late in the war, the straight crossguard variations of the Type 30 would be the most suitable to mate with them rather than the earlier hooked quillon types. This straight guard bayonet with blued blade made by Matsushita Kinzoku under Kokura Arsenal supervision would be a typical example of a bayonet that is a rough match in terms of period and style.

Here it is mounted on the rifle. The rifle and bayonet together are 150 cm long (about 59').

Two close-up views of how the bayonet attaches to the rifle.

This rifle is also often associated with a short version of knife-bayonet previously now known as the Test Type 1 (there was also a 'Special Purpose Test Type 1' that showed some German influences). Prior to the publication of the LaBar book, these weapons were erroneously referred to as the 'Type 100 Bayonet' because it was thought they were made for use with the Type 100 machine gun. They were made by Toyoda Automatic Loom Works. I am working on a deal to get both versions, but don't have them yet. When I get them, probably in late 2009, I will post photos here. Until then, you can also get more details on these two short bayonets in the following two books on Japanese bayonets:

Bayonets of Japan: A Comprehensive Reference on Japanese Bayonets, by Raymond C. LaBar (Raymar Inc., Tunnel Hill, Georgia, 2007), pp. 88-92. (this is the newer of the two books. It is both easier to get and much more comprehensive)

Japanese Bayonets: The Definitive Work on Japanese Bayonets 1870 to the Present, by Larry Johnson (Cedar Ridge Publications, Broken Arrow, Oklahoma: 1988). pp. 30-38. (out of print for many years and very hard to find, but many people still refer to it if they have one since the LaBar book is so new some people don't even know it is out yet).

Here is a link to a website with photos of one of the short knife/bayonets, which the site refers to as a 'Type 2':

Type 99 Arisaka Serial Numbers Diagram

There were special ammo pouches for paratroopers. I don't have one, but they had numerous small pouches on a belt instead of the standard 'two-small-in-front, one-large in back' set of pouches used by the regular infantry. There is a line drawing from a period manual on page 226 of the Derby and Brown book Japanese Military Cartridge Handguns 1893-1945.

More on Japanese Paratroopers:

There is a great DVD of a period propaganda film on paratroop training. It is only in Japanese (no sub-titles) and you have to have a Japanese or region-free DVD player to run it, but the images are well worth it.

The title is Sora no shinpei: Rikugun rakkasanbutai kunren no kiroku ('Divine soldiers of the sky: Record of the Training of Army Paratroop Units'). You can get a copy in Tokyo at the bookshop in Yushukan, the museum associated with Yasukuni Shrine. I think I have also seen it in major Japanese bookstores. It is number 12 in a series of these re-issues of Japanese war-time propaganda movies about the military.

Observations: (by 'Claven2')
Primary infantry rifle for the Imperial Japanese Army during World War 2. Check for matching serial numbers on left side of receiver and the last 3 digits of the serial number on the bolt shroud, bolt body, firing pin and extractor. Check for a cleaning/stacking rod provision and if present, ensure you get the rod (replacements are unobtainium). Check for availability of serial numbered action cover if an early rifle, which by itself can add approximately $100 value to the rifle. Lastly, check for a non-defaced chrysanthemum stamping over the model designation on the receiver ring as this adds greatly to collector appeal.

Arisaka Type 30 Parts

1. The Arisaka T99 was the much anticipated replacement of the earlier 6.5mm T38 infantry rifle in use since before WW1. Initially, both T99 Long rifles and T99 rifles were produced with the shorter of the two being intended for cavalry. Troop trials showed, however, that the shorter rifle was much more useful and production switched entirely to the recognized standard T99 pattern in the first year of production (1939).
Early on, rifles were made with sliding action covers, a folding monopod, anti-aircraft sighting arms on the rear sight, chrome lined bore and chrome plated bolt face. As the war progressed, supplies of suitable ordnance steel dwindled and the need for rifles increased dramatically. Gradually, early features were deleted and the level of finish applied to the rifles decreased. These were considered “transitional T99 rifles” and were generally made from late 1941 to about late 1943. The Transitional rifles were made to be functionally the equivalent of the early war rifles and even had provision for most of the early war features (except the useless monopod) – the idea being that when Japan won the war [sic], these rifles would be upgraded. As the situation worsened for Japan in late 1943, the “Substitute Standard” T99 was introduced – it is often mistakenly called a “last ditch 99”. These rifles were made as cheaply and quickly as possible. They are often characterized by crude welds, wooden butt plates, lack of any refinement and crude fixed sights with primitive stocks compared to earlier rifles. Contrary to popular belief, they are safe to shoot if in serviceable condition but the general lack of quality is quite evident. It is my personal belief that these rifles were never built with upgrading to full T99 standard in mind.
The rifle pictured here is a very early 33rd series rifle from the Toyo Kogyo factory in Hiroshima. The characters on the receiver ring translate to “type 99”. Toyo Kogyo was Hiroshima's largest employer, and while the factory was located far enough from the city center to avoid serious damage from the world’s first aggressive use of an atomic blast, many of Toyo Kogyo's employees were not; 400 workers died and the factory never made firearms again. Today the factory is owned by Mazda Motors. Toyo Kogyo made rifles from the 30th series to the 35th series for a total production of approximately 557,000 rifles, about 200,000 or so of which were substitute standard models.
Serial number observations indicate Toyo Kogyo made the switch from transitional T99 production to Substitute standard production within the first 9,000 or so rifles of the 33rd series, making this rifle one of the last transitional rifles they ever produced. In the pictures you can see that cosmetic finishes were pretty much a non-issue at this point on all non-critical surfaces. Aside from the ground chrysanthemum, this rifle is in excellent condition or a rifle of its type. The rough surfaces seen on the hinged floor plate, trigger guard, etc. are not due to pitting – the parts themselves were basically raw stampings and forgings, only lightly ground and blued at manufacture. The receiver cover, monopod, monopod boss and AA sighting wings are deleted on this rifle, though the receiver is still machined to accept a cover and the rear sight is machined for wings. The nosecap is also a 2 screw type, not the earlier 3-screw model. The stock has no drainage holes, but retains the early war small diameter recoil bolt. The stacking rod has been shortened and is no longer a cleaning rod. The bore is chromed, but the bolt face is not. Unlike the other T99 factories, Toyo Kogyo and Kokura arsenals continued to use the olive-shaped bolt knob and machined safety shroud until the end of production in 1945.
The stock, like all T99 rifles, is made of two pieces, with the toe of the butt spliced on. The finish is a reddish varnish called Urushi. Do not sand these stocks – Urushi is a powerful skin irritant in dust form. This stock retain the early war thick butt plate.
When reading the markings on the receiver wall, the first character, a kana, indicates the production series in Japanese, the next numbers are the serial number in Arabic numerals, followed by the Arsenal mark (1 or as in this case, 2 characters) and finished by an inspector’s Kanji.
The vast majority of rifles the collector will encounter have defaced chrysanthemum markings. This is because upon Japanese surrender in 1945, soldiers in the field were ordered to deface these markings so as not to dishonor the emperor and also because Gen. Macarthur issued orders that the same be done to all officially captured rifles. The US gov’t didn’t want to debase the Emperor’s power as it was felt he would be needed to aid in reconstruction of the country post-war. Only a small percentage of Arisaka rifles escaped this fate.(Feedback by 'Claven2')
