List of Japanese weapons for future campaigns

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

9

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

10

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?

11

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!

12

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

13

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

15

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?

16

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).

17

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.

Don’t mind, Japanese weapon names always make confuse us…

p.s.
Navy landing forces’ infantry also used naval Type 92 (Lewis) machine gun with pan magazine for ground battles during WW2.

about Experimental SMGs

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.

21

will it ever be a fair fight regarding tank vs tank? against US?

22

No Japanese tanks which were sent to battlefield can penetrate front armor of M4 Sherman
In other hand, all US tanks can penetrate from armor of all Japanese tanks which were sent to battlefield.

In case of early battles, there were only M3 Stuarts so it will be fair battle, but late war battle will be a non-balanced battle
(front armor of M4 Sherman is 50 mm, but it have inclined armor so it is difficult for Chi-Ha’s 47 mm cannon to penetrate it)

If implement SPGs like Ho-Ni I and Ho-Ro, Japanese tanker can destroy M4 Sherman but they are not well-protected so infantry can destroy such vehicles easily.

Japanese Aircrafts used during 1936-45

Japanese had lots of domestic-design military aircraft during Asia-Pacific War. This sheet list mass-produced fighters and bombers used during the war. It contains basic performance which is affecting to the game and I hope it will be help for you to consider about future Japanese campaigns.

Note:

  • Prototype aircrafts are not included.
  • Alphabet after machine guns mean subtypes.
    A: Ko
    B: Otsu
    C: Hei
    D: Tei

For the SMGs they have the japanese army used the MP34 and something that is called the Type BE ? Which is just the mp28 or 18 with 40 round mag… i found out about this from another game the source might be unreliable.

The japanese also used a Type 98, basically an mg15

25

MP34(o) is German name of S1-100. Japanese name is Type Su automatic pistol (ス式自動拳銃).
Type Be automatic pistol (ベ式自動拳銃) is SIG-Bergmann M1920, an improved MP18 with 50 round magazine. Sometimes it is confused as MP28.
Both SMGs were used by Imperial Japanese Navy.

Surely, Type 98 swivel machine gun (九八式旋回機関銃) is based upon MG15, but it was aviation machine gun for bomber’s flexible mount.

Wonderful, sire. This is a pretty nice list, and really good. However, this list also shows the reason why we can’t have a 1944 Pacific campaign, unless you want to add in imaginary weapons, such as captured Johnson M1941 from the Dutch, or the Chi-To that never left the Japanese homeland.

However, we can focus on the 1942 Malaya and East Indies Campaign. And of course, scrap the Semi-Auto, as neither side did use significant amount of semi-auto rifles during the campaign with the exception of the Dutch with their 1500 Johnson M1941 rifles.

I could list em up like this:
Arisaka Type 30 - Enfield M1917
Arisaka Type 38 - Lee-Enfield SMLE (Indian Pattern)
Arisaka Type 99 - Lee-Enfield Mk IV
Arisaka Type 99 with Type 100 Grenade Discharger - SMLE with grenade launcher
Type Hei experimental rifle with 10 rounds magazine - Farquar Hill with 10 rounds magazine

If you want to, you could add in captured French rifles from Indochina for either sides. An extra Lebel or Berthier wouldn’t hurt. We may also put in Burmese Mausers if you desire so.

As for Submachine Guns, the Japanese are not in a good position at all. However, I could add in some interesting stuff. This also includes taking Thai SMGs

Type 100 SMG - Sten Mk I
Solothurn SMG (MP-34) - MAS-38
Thai MP-35 - Thompson M1
Experimental Model 2 SMG (30 rounds) - M1928 Thompson (30 rounds)
Experimental Model 2 SMG (50 rounds) - M1928 Thompson (Drum Mag)

The LMG is easier than the SMG because the Japanese already had access to some nice SMGs
Type 96 LMG - Vickers-Berthier (this LMG was adopted by the British Raj, but not the British themselves)
Type 99 LMG - Bren Mk I

Heavy weapons are possible to think about. The Japanese do have access to some nice flamethrowers. But, let’s go anyways.
Type 89 Grenade Discharger - Two Inch Mortar
Type 93 Flamethrower (yes, it was used) - Harvey Flamethrower
Type 97 20mm Anti Tank Rifle - BOYS AT rifle (this is done to balance the fact that the allies simply have better tanks)
We shall not put in any rocket launchers here. Nope, just nope

Now, we can come to the tanks. 5 tanks, 2 for Tanker I, 3 for Tanker II.
Ha-Go - A13
Type 98 Ke-Ni - Tetrach

Type 97 Chi-Ha (with HEAT Rounds) - Daimler Mk II
Type 97 Chi-Ha Kai - Crusader Mk II

If we are desperate, we can add in the Thai Vickers 6 ton.

As for aircrafts, we have the most legendary stuff. The story of legends.
Mitsubishi A5M/Ki-27 - Hawker Hurricane Mk I
Ki-43 Hayabusha - Supermarine Spitfire Mk I
Mitsubishi A6M2 mod.11 (army Zero) - Supermarine Spitfire Mk IIb

Aichi D3A/B5N - V-156 B1

Ki-45 Toryu - Beaufighter Mk V/de Haviland Mosquito

Ayy, Grandee, this is harder than it looks. Just add stuff.

It sounds nice idea!
However, in my opinion there are some problems.

30th Year Type rifle was already retired so it should be battlepass or premium weapon. For such purpose, Type 44 carbine would be suitable.

I think its not a good idea because Type 97 autocannon is too heavy… Its weight is 60kg! Its just prototype but experimental 13mm is still better than it.

Its not a problem, but I want to see SIG-Bergmann M1920 (Type Be machine pistol) of the Japanese navy.

Type 98 Ke-Ni was never sent to overseas. Also, mass-production was started since June 1942 so it was not exist during the Malayan Campaign.

Mass-production of Type 3 HEAT shell was started since 1944.

Some opinions for aircraft:

Single-engine attacker
I think army’s attackers like Type 98 light bomber (Ki-32) are better than naval bombers . Normally, army’s combat was supported by army’s aircrafts.
Ki-32 was a bit old but it was used at the battle of Singapore etc.

Twin-engine attacker
In case of Malaya, Type 99 twin light bomber (Ki-48) vs Blenheim Mk.IV will be good. In battle of Malaya, British forces used Blenheim, and one of them shoot down very famous ace-pilot Tateo Kato.
In other hand, as far as I remember, there’s no Beaufighter or Mosquito in there.

Fighter
In that time there aren’t Spitfire in Malaya… British forces had only Buffalo and Hurricane.
Also, A6M2 mod.11 is very-early production model. Produced only 64 and used in early 2nd Chino-Japanese war for strategic bombing by navy. When start the Pacific war they’re already replaced by mod.21.

How about something like this:
Type 97 Fighter (Ki-27) - Buffalo Mk I
Type 1 Fighter Model 1 (Ki-43-I) - Hurricane Mk I
Type 1 Fighter Model 2 (Ki-43-II) - Hurricane Mk II

Ki-43-I had two 7.7mm and Ki-43-II had two 12.7mm.
