List of Japanese weapons for future campaigns

Introduction

Recently we often see suggestion or expectations for Japanese forces. However, about Japanese weapons there are some confusions like year and places. For purpose of discussion I made several tables of weapons and their adopted year, service and number of production.
Additionally, for armored vehicles I made general sheet for campaigns where they fought. I hope it can be help to find where Japanese tanks fought.
Mainly I listed WW2 weapon. Very old weapon are not listed.

Please note that model year (“Type XX”) and actual adopted year are different. In example of “Type 97 Sniper Rifle”, “97” means imperial era 2597 = western era 1937, but actually it was adopted in 1939.
In many case, weapons enter service after adopted but there are several exceptions. For example, mass-production of Type 99 Short Rifle was started since 1941 in spite of it was adopted in 1939.

Captured Rifle

Japanese captured lots of rifles. In Japanese documents, such rifles were called as below.

  • 中国式小銃 (Chinese Rifle)
    • Probably Zhongzheng Rifle, Type 88 Rifle etc.
    • Their ammunition, “モ式小銃弾薬包” (Mauser Rifle Cartridge, 7.92×57mm Mauser) was adopted and mass-produced at Japanese arsenal for these rifles.
  • 英式小銃 (British Rifle)
    • Probably Lee-Enfield Rifle.
    • They are using “米式小銃弾薬包” (American Rifle Cartridge, probably it means .30-06 Springfield). This ammunition was not mass-produced at Japanese arsenal.
  • 米式小銃 (American Rifle)
    • Probably M1903 Springfield, M1 Garand, M1 Carbine etc.
    • Due to such weapons were captured early time of war, most of the captured ones are Springfield

Semi-Auto Rifle

Japanese operated several captured weapons include M1 Carbine and Garand. Different to Chinese captured weapons, they did not mass-produced ammunition for U.S. rifles, but some extent of them were deployed and used in the front unit.
Especially in battlefields like the Philippines, a large number of U.S. weapons were captured, so it seems that a considerable number were used in the defense of Philippines in 1944-45.

Officer’s personal handguns (Commercially available, made in Japan)

Officers purchased own handgun from market. Due to this system, Japanese army used a huge number of types of pistols.
Domestic-production pistols were cheaper than imported goods and was attractive to poor officers.
Apparently , in English speaking area such Japanese pistols have strange customary names. For purpose of them I noted such names. I’m not sure because I’m Japanese, so if there’s mistake please tell me.

Generally, FN Browning M1910 and Colt M1903 Pocket Hammerless were popular among officers. However, they also used lots of various pistols of FN, Colt, Mauser, Astra, Ruby, Royal, Ortgies etc.

Heavy Weapons

Personal-Carried Motor

In this table, I listed 5-cm caliber light-weight infantry motors which is suitable for the game.
Generally, Japanese “light” motor corresponds to Western “heavy” motor, and Japanese “heavy” motor corresponds to Western “siege” gun. Caliber of Japanese light motors were about 90-150 mm, and heavy motors were 275-305 mm!
Also, sometimes “motor” are called “grenade launcher” or “infantry gun” so it make confusion.

When I look at the SMG and Semi-auto Rifle list

Well, at least SMG are still better that semi-auto rifles… MP18/20, MP28, S1-100, Type 100 early, late, navy were not a prototype and used on actual battles.
Semi-auto rifles are serious problem… so I want to see early WW2 battles than late for Japanese.

small note, if we could make the Japanese high-end bolt-action shoot with a ROF 90-100 we could avoid giving them semi-automatic since they have never used it and avoid finding ourselves due to laziness of the development team with the Japanese who use the gewer41

5 Likes

I forgot to list, but Japanese used semi-auto rifles like M1 Carbine and Garand, too. M1 Garand was unpopular because it was too large, but M1 Carbine was popular among soldiers because of their small physique.
Especially, in the battle of Philippines etc., Japanese garrisons often equipped with such captured weapons. (Of course, there would have been more Springfield guns than those.)

At least, I believe they are better than Gewehr 41 or bolt-action with unhistorical extreme rate of fire.

Is a gigantic no! at this point we might as well give them the stg as in COD and call it a day

Oh really?
I thought it sounds still better than German weapons…

Give the same weapon to both faction is good for you, wy dont give ppsh41 to german in berlin and moscow at this point because they used captured ppsh41 or t34-85

Thanks for doing this, this will make any of my future proposals far easier. Also, I have seen reports of US troops capturing Type Hei Rifles while island hopping, or a version of the Pederson Rifle chambered in 6.5 x 50 mm Arisaka, about equal to 6.5 x 52mm Carcano which could make it a counter to the M1 Carbine. I also saw you accidently wrote the Experimental Automatic Rifle Otsu on the table twice. Was one of them supposed to be a Type Hei Rifle?

I’ve heard Type Hei captured at any website but I don’t know well… (I’m Japanese and not familiar with English so its hard for me to search US docs)
Anyway if the war hadn’t broke out, it might make sense to put them in as an alternative, as it was either Ko or hei that was adopted.

Yes, its my mistake. I fixed it. Thank you!

Update:
Added late-war strange weapons. (25 mm rocket rifle and Type 4 double-barrel hand shotgun)

If you searching full-automatic rifle for Japanese, this weapon seems better.
In my personal opinion, multiple Japanese soldiers are armed with this non-adopted experimental assault rifle is a nightmare, but I added to list for discussion.

Due to I can’t find English website which is have data of this weapon, I wrote wrap up.
It was gas-operated toggle-lock light-weight machine gun for 6.5 mm Type 38 cartridge. Adoption was rejected due to its extremely low reliability.

Evaluation by examiners (wrap up)

  • The accuracy at the time of continuous firing is quite low.
  • There is a risk of cocking-off if the barrel is loaded while it is heated.
  • There is a defect in the safety device.
  • It is worried about mass production during the war because I use a lot of patented bullions.
  • It is inconvenient to handle because the magazine is on the lower side.
  • The mounting position of the sighting device is bad, and it is difficult to aim at the time of continuous firing
  • There are so many mess feed and it is difficult to shoot all 20 shots.
  • The ejection system is Pedersen type, and there is almost no problem in operation.
  • Fire rate is too high (720rpm) and it is not adjustable. Fire rate should be about 500 rpm.
  • The rod was so fragile that I had to interrupt the test.
  • Accuracy was worse than Type 99 LMG. Even if it is equipped with a shield and the weight is the same as Type 99, accuracy is still inferior.
  • At the time of continuous firing, only the first bullet hit the target 300 m away, and the hit accuracy could not be calculated.
  • Recoil was not measured, but gunner feel it is less than the 11th Year Type LMG.

May I ask a favour? There are records of a 97 round pan magazine for the Type 92 machine gun. Do you know anything about this magazine, like if it has a name like the Patronentrommel for the MG 34? thanks

Nice list. Some I didn’t even knew.well done.

Side question.
The Japanese will be inferior to alies forces regarding weapons and specialty regarding tanks right?

As far as I know, army’s Type 92 Heavy Machine Gun (九二式重機関銃) did not had any pan magazine.
In case of navy’s Type 92 7.7 mm Machine Gun (九二式七粍七機関銃), it have standard 97 round pan magazine but it will not have any unique name because it is just a standard magazine. It was a licensed production model of the Lewis gun and magazine will not compatible with army’s Type 92 heavy machine gun: navy’s Type 92 is using rimmed 7.7x56mm cartridge (.303 British) but army’s Type 92 is using semi-rimmed 7.7x58mm cartridge (Type 92 cartridge) or rimless 7.7x58mm cartridge (Type 92 / Type 97 cartridge).

Surely armored vehicles are inferior to US and British commonwealth army. It’s even jokingly said that the strongest tank in the Japanese army is the M3 Stuart. (Japanese army operated lots of captured M3 Stuart)

In other hand, in China, French Indochina (had only FT-17 and FT-31) or Dutch East Indies (had only armored cars), Japanese armored vehicles superior to such colonial forces’ tanks.

About infantry weapons, it may be a little difficult to evaluate.

Bolt-action rifle

Hit power of 6.5 mm (Arisaka) rifles will be inferior to Chinese 7.92 mm (Mauser) rifles or Allies 7.7 mm (Springfield) rifles. However, the recoil is small, so it may be suitable for sniping.

Semi-auto rifle

R.I.P.

Submachine gun

Pros

  • Large 50 ammo magazine (SIG M1920)
  • High rate of fire (Type 100 SMG/Late and Naval model, 700-800RPM)
  • Have a bayonet

Cons

  • Hit power is lower than .45ACP (Navy: 7.63x25mm Mauser / Army: 8x22mm Nambu)
  • Low rate of fire (Type 100 SMG/Early, 450rpm)
details

Navy
Japanese navy used SIG-Bergman M1920 (MP18/20) and Steyr-Solothrn S1-100 (MP34o) SMGs. Both guns were using 7.63 mm so hit power is inferior to original German service, but I’m not sure comparison with allies.
S1-100 had 30 round magazine, but SIG M1920 had large 50 magazine so it will be good advantage. In addition, in Japanese service both SMGs had bayonets which is useful in close-range combat.

Army
Except for several prototypes, Japanese army had only Type 100 SMG but it is possible to separate to three models. They were using 8 mm 14th Year Type pistol cartridge (aka 8mm Nambu). I’m not sure about cartridge but muzzle energy was not a good (similar to .380 ACP).
In case of Early (1942) model, fire rate was limited to 450rpm. In Late (1944) model and Naval model, they omitted rate reducer to improve productivity so fire rate increased to 700-800 rpm. Early model has good accuracy in exchange for a slightly lower rate of fire, but the late model will have a higher instantaneous firepower but will be difficult to control the aim. It seems similar to relation of M3 SMG and M1 Thompson.
Similar to naval one, Type 100 SMGs also had bayonet. I think it will be useful.

Light machine gun

Pros

  • Have a bayonet (Type 96, Type 99)
  • Have a scope (Type 96, Type 99)
  • Perhaps recoil is lower than other countries’ light machine guns
  • Magazine is larger than Browning M1918 (20 rounds vs 30 rounds)

Cons

Shotgun

Japanese navy requisitioned about 50,000 shotguns for substitute of rifles at jungle warfare. All of them were 12-gauge which is similar to allies.
It include single-shot, double-barrel and repeating fire guns. They will include not only bolt-action, pump-action but also semi-automatic like Browning Auto-5.

Anti-tank weapon

Japanese anti-tank weapons are quite inferior to allies.
At most, 8cm rocket launcher (HEAT shell) of the navy was sent to battlefield but others like army’s Type 4 7.5cm rocket launcher had never sent to battlefield.
Generally they used magnetic mine, HEAT hand grenade and HEAT rifle grenade.

Also, Japanese anti-tank guns are limited to 47 mm. It cannot penetrate front armor of M4 Sherman and Matilda Mk.II. For late-war battlefields we need to implement field gun for engineer’s gun.

Infantry mortar

There will not be much difference between the two armies.
Type 89 Heavy Grenade Discharger seems similar to British Two-inch mortar. Also, compare to American M2 mortar, weight is lighter than it.

note:
Japanese “Light” mortar is not suitable for game because their caliber is 75 ~ 150 mm. (in-game mortar: about 50 mm)

Ok, thanks. I knew the Navy’s type 92 was often mounted on the back of light bombers, and that is why they used the larger mag, I just wanted to know if it had a unique name. I probably should have specified which Type 92 I was asking about. my bad.

Summary

About Prototypes

Experimental automatic pistols: Very early prototypes build by Tokyo Arsenal. English name is “Tokyo Arsenal Model 1927” and “Tokyo Arsenal Model 1928”.
They were manufactured by Tokyo Arsenal (東京造兵廠, English name is “Koishikawa Arsenal”). First-stage prototype was tested in March 1927 and compared with Thompson and Bergmann. It had extremally high fire rate and reliability was low. Second-stage Prototype was manufactured in 1930. They improved first stage to increase weight and decrease fire rate. The project disappeared spontaneously and was taken over by research on new machine pistols.
Please note that naval project and this army’s competition did not have any relations.

Nambu machine pistol Mark 1 and Mark 2 were designed for basic research. Design of Nambu Mark 2 was succeeded by Experimental Model 1 machine pistol in 1936. It was tested in December 1936 but there were some issues. The problem was fixed and the second test was held in April 1937.
In parallel, Experimental Model 2 machine pistol was completed and tested in June 1937 but performance was not a good and rejected.

In August 1937, a practical test of Experimental Model 1 was conducted at an infantry school and a cavalry school, and some requests were made. Based on Experimental Model 1, a new Experimental Model 3 was manufactured by incorporating the opinions of infantry and cavalry schools.
14 prototypes were manufactured and compared with new Bergmann submachine gun with Parabellum ammo. In This exam, they considered it have enough specification but few point was pointed out. Following it, 10 prototypes were modified. In addition they manufactured five Model 3 Modification Ko and five Model 3 Modification Otsu. Finally, Model 3 Mod. Otsu was adopted as Type 100 Machine Pistol in February 1941.

In later, Experimental Model 2 attracted attention as a small weapon for tank soldiers. In late 1940s Kokura arsenal build improved model of Model 2, but Japan was surrendered before it was adopted.
