Ok I think this will be the final Japan Tech tree after the Pershing gets released. Its the most realistic one we can get. Also will be my final suggestion about Japan cuz I can’t do nothing better then this. I will start with the Small Arms:
I. Small Arms
- LMGs:
-Add new LMG to BR 3 ZB 30:
- Give Type 96 light machine gun optic stays in the same BR
-Move Type 99 light machine gun to BR 4 give it optic:
It can be given better stability and the optic will make it perfect Japanese BR 4 lmg.
Japanese type 99 and type 96 must have optics for the simple lack of other automatic weapons or semi-automatic weapons with optics.
-Add New Te-4 LMG ( Type 89 Machine Gun for ground use) to BR -4:
The other option is SIG KE7 with 50 round mag but i think Te-4 will be better option.
-Add Type 98/Type 1 machine gun to BR 5:
its the only realistic option for BR 5 the other options will be guns from the future like : NTK 62 or something crazy like Type 99 canon that had 60 or 100 drum mag but its a auto canon I don’t think giving infantry auto canon will be a good idea : 
- SMGs:
-Add Tokyo Arsenal Model 1927 with 30 round detachable stick to BR 4:
-Move Tokyo Arsenal Model 1927 50 Round drum mag to BR 5:
Come on guys its BR 5 weapon its not for BR 4.
- Rifles:
-BR 2 new rifle – Type 22 Murata Repeating Rifle
-We move Otsu Rifle to BR 3: 
-BR 4 new rifle – The Hino Kamuro M1904: Japans Rear Automatic rifle 15 rounds mag: 
-BR 5 new Type Hei Automatic Rifle 20 round mag: 
-BR 5 new Type Hei Automatic Rifle 30 Round mag:
4.Mortars:
-New Type 99 81 mm mortar BR 5: 
5.New Infantry Vehicles: -Add to BR 2 Raider Squad Rikuo Type 97: 
-Add to BR 3 new APC Driver Squad Amphibious Truck “Su-Ki”: 
- Type 4 90 mm AT Rocket Launcher to BR 4 :
And that’s it with the infantry now we move to tank and plane balance.
II. Tanks :
-Move Chi-Nu to BR 3:
-New BR 4 tank – Chi-To:
-New BR 4 Tank Chi-Ri II: 
-New BR 5 tank Ho-Ri Prototype:
I will be short here simply Japan is not a tank faction this is the only 3 important changes to tanks that must be made in the near future. In BR 5 only Ho-Ri will be playable everything else that can be added will be scraped before you even put your feet on the battlefield so better have few playable options then adding more useless options.
III. Planes: -D3A1 Moved to BR 1:
-B5N2 Moved to BR 2:
-D4Y1 Replaced with D4Y2 and moved to BR 2 ( 4 x Type 3 No.1 Mod.28 Mk.1 rockets) and ( * 1 x 500 kg Number Type 2 50 Model 1 GP(SAP) bomb (500 kg total):
-Add Ki-48-II otsu ( 1 x Ki-148 I-Go Model 1B missile) to BR 3:
It will be the perfect Sherman hunter. The rocket will give you big chances of destroying big targets much better then bombs.
-Add D4Y3 Ko ( 3 x 250 kg Navy Type Number 25 Model 2 bombs (750 kg total) to BR 3:
-Add Ki-102 otsu ( 1 x Ki-148 I-Go Model 1B missile) BR 3: 
-Add Ki-43-III otsu Hayabusa to BR 3:
I think the best option for BR 3 fighter that wont be another Zero.
-Add B7A2 Ryusei ( 1 x 800 kg Number 80 Mod. 1 bomb (800 kg total) to BR 4
-Add A6M5 Hei ( 10 x Type 3 No.1 Mod.28 Mk.1 rockets) to BR 4:
-Add Ki-83 to BR 5
-Add J2M3 Raiden Mod.21 (with rockets) to BR 5
-Add Ki-84 hei to BR 5
Well Japan as a faction must have very big plane collection to compensate for the lack of tanks and this is the most interesting ones that will provide you with good anti armor and anti air capabilities. The big rocket planes will compensate for disadvantage in tanks.
Hope you like it i think its the best set up I manage to make about BR 5 cuz there is not many options but i think its enough i hope something close to this will be the setup for Japan after BR 5 is released.
