Ha-Go
BR worthiness: BR I
Changes Needed
1 Swap the 37mm Type 94 Tank Gun (575m/s) with 37mm Type 98 37mm Gun (704m/s)
Ha-Go’s initially used the Type 94 but after 1938, all Ha-Go’s had the Type 98 gun.
2 Model Face Hardenned Armour into the game because it used FHA not RHA which would give it substantial buff against low caliber machine guns compared to RHA. For example When M2 .50 cal penetrates 19-20mm of RHA at 500 yards, it would only penetrate 15mm of FHA and Ha-Go had 12-13mm of FHA

Next on the progression line should be the…
Type 2 Ka-Mi
BR worthiness: BR I
Changes needed
Model its Face Hardenned armour
::::
Type 97 Chi-Ha
BR worthiness: BR I
Changes needed
1 Model its Face Hardenned Armour, right now its possible to penetrate it with .50 cal at a distance but with this change, .50 cal wouldnt penetrate even at point blank range under the most ideal conditions, even against its side armour
2 Should be a main tech tree tank

Chi-Ha Kai

Changes needed
1 Model its Face Hardenned Armour, right now its possible to penetrate it with .50 cal at a distance but with this change, .50 cal wouldnt penetrate even at point blank range under the most ideal conditions, even against its side armour

:::
Type 1 Chi-He
BR worthiness: BR II
Changes Needed
1 Model its Face Hardenned Armour, will make it much harder to penetrate with 37mm non capped AP US rounds or Soviet non capped 45mm AP rounds.
:::
Chi-Ha 12cm Short
BR worthiness: BR II
Chages Needed
1 Move from BR III to BR II
2 Model its Face Hardenned Armour
Can be a premium tank
:::
Type 2 Ho-I
BR worthiness: BR II
Changes Needed
1 Model its Face Hardenned Armour, will make it much harder to penetrate with 37mm non capped AP US rounds or Soviet non capped 45mm AP rounds.
:::
Type 3 Chi-Nu
BR Worthiness: BR III
Changes Needed
1 Model its Face Hardenned Armour, will make it much harder to penetrate with 37mm non capped AP US rounds or Soviet non capped 45mm AP rounds.
2 Add its missing Toku Kou AP Shell (6.64kg at 683m/s) which according to japanese tank usage manual from May 1945 says could penetrate frontal M4 Sherman hull armour from 600m and up to 800m vs frontal driver hatch.
:::
Add Type 3 Chi-Nu II
BR Worthiness: BR III
Would be high end BR III tank equivalent to Pz. IV H, less armour but more penetration
:::
Type 4 Chi-To Prototype
BR Worthiness: BR IV
Changes needed
1 Swap the Type 90 sharp pointed HE shell with low TNT amount to Type 4 HE or Type 98 HE shell with 800-900g TNT equivalent which would give it at least double the explosive amount than it currently has, putting it on par with Chi-Nu with Type 3 gun right now in anti infantry effectiveness
2 Add Type 4 APCR (1110m/s, 212mm @ 0m penetration)
Premium Tank since its the pre-production prototype
:::
Add Chi-To Production
BR Worthiness: BR IV
Main Tree since this was the main production version, although 5-6 incomplete tanks were built
:::
Type 5 Chi-Ri
BR Worthiness: BR IV
Changes Needed
1 Reduce BR from V to IV
2 Add Type 1 AP shell for the hull mounted 37mm gun
3 Swap the Type 90 sharp pointed HE shell with low TNT amount to Type 4 HE or Type 98 HE shell with 800-900g TNT equivalent which would give it at least double the explosive amount than it currently has, putting it on par with Chi-Nu with Type 3 gun right now in anti infantry effectiveness
4 Implement the Autoloader properly. 1 Shell in breech, 2 on a rack. 3 consecutive shots at 3.0-3.5 sec reload and when its completely empty, same reload as Chi-To since the loader would be putting it straight into the breech, not on a rack. When not firing the shells, the rack will replenish at same rate as single shell reload when empty.
5 Add Type 4 APCR (1110m/s , 212mm @ 0m penetration)
:::
Add O-I Heavy
All of the tank was built except the turret roof by Early 1943 and it did mobility tests. Whilst no actual pictures of the tank exist, we have details of the mobility test and results to prove it was built and tested to prove its existence. However by mid 1943, Japan also saw no use for it it since it was suppose to be a moving fortress in Manchuria against the Soviet Union after Khalkin Gol but the war has now moved to the Pacific. It was scrapped in Late 1943 for metal which japan was in shortage of. The 150mm Type 96 Howitzer gun uses the same ammunition as the 15cm gun on Ho-Ro tank destroyer but since its a longer barrel howitzer, it shoots shells at medium velocity rather than very low velocity. It wont rely on penetrating tanks but HE derping tanks to destroy them with a long reload. It has 150mm frontal armour so its not too overpowered, 90mm on M26 will be sufficient with APCR to reliably pen, super pershing with 90mm APCBC or IS-2’s 122mm APHE will easily penetrate it, without needing APCR. In all honesty, if it got added in War Thunder it would be nothing too crazy, 5.7BR worthy.
The 150mm Type 96 Howitzer was also used as artillery piece in the field by the Japanese Forces so the gun itself, US was already familiar with and with its APHE shell, recorded a penetration of 125mm @ 250 yards. Nothing special, better off using the HE shell.
BR worthiness: BR V
Theres already a War Thunder model for it

Change needed for all tanks
Fix non capped AP shell performance, this applies to these tank and every other tank in the game, but since japan relies on AP shells, its especially significant for japan.
https://community.gaijin.net/issues/p/warthunder/i/hLPH8HLThguu
This would significantly boost japanese shell penetration performance, especially vs armour at high angles.
