Do you have any information on the Toku Kou, Experimental 47 mm Type 1 Tungsten APHEBC, and Nickel Chromium Steel Otsu AP shells?
In game weight of Type 4 kou was calculated with this method
9.035 - 6.605 = 2.43 kg
9.18 - 2.43 = 6.75 kg
Spoiler
But this Type 4 in game has the HE filler
Also interesting that here is another weight of projectile Type 1 APHE
In game it is:
Spoiler
This weights of projectile and filler has been taken from TM 9-1985-5 Japanese Explosive Ordnance (Army Ammunition, Navy Ammunition) 1953
Bug report needed?
And acceleration is exactly what the Jagdtiger lacks. The Ho-Ri can get around the map stupidly fast for something of its size and armor.
I found information about the Nickel-Chrome AP shell.
The Japanese Army, based on their experiences from the Battles of Khalkhin Gol, sought AP shells capable of penetrating the armor of future Soviet heavy tanks. This Nickel-Chrome AP shell was developed by Nippon Yakin Kogyo Co., Ltd. in May 1941. The steel used for the AP shell is named NK Steel Mk 3. Experimental results showed that this Japanese-made AP shell was superior to American and German-made AP shells. According to the experiments, the Soviet-made AP shell performed the best, but it was judged to be equivalent. Nippon Yakin Kogyo received an order from the Japanese Army for mass production of 75 mm AP shells and produced 650,000 Nickel-Chrome AP shells in 1942.
“Sixty-Year History of Nippon Yakin Kogyo”. Published by Nippon Yakin Kogyo Co., Ltd. 1985. pp. 56-57.
This is an armor penetration test of a nickel-chrome AP shell conducted by the Army Technical Headquarters in September 1941. This table has some useful looking data that’s been picked out and translated.

Really surprised how it was possible to find so much valuable information.
So in fact chrome-nickel AP rounds was in 1941 already? It is similar to what we’ve seen in Type 1 47mm prototype cannon tests where 47mm and 37mm Chrome-Nickel APHE was mentioned. But isn’t there any information about late war Chrome-Nickel rounds? As for example there is the reports by US that new shells of Type 1 47mm can penetrate ~115mm of armor. Can’t it be late-war Chrome APHE?

You’re amazing, thank you.
Now if only we can get such information into War Thunder.
Also, @skultew1234 115 mm is insane. Sadly we don’t know what it was. Maybe the Experimental 47 mm Type 1 Tungsten APHEBC, Type 4 AP, or some solid shot shell. Or maybe some HEAT shell?
Just found a goldmine of rare Japanese vehicles, here are some highlights that I find to be quite interesting.
Translate says it’s a conqueror with a 114mm gun, but how could this be Japanese?
Mysterious heavy tank, could it be Type 95? Or perhaps even the O-I?
Type 61 with sideskirts and spaced armor
We finally see the Toyota AA gun carrier up close, it is said to be the “GB” model truck
Chi-Ha Kai with 57mm gun?
A few unknown vehicles even more mysterious than the rest
I have even more rare photos of already existing vehicles, for now I will save them for another post.
Do you have the source/sources for the first two posts?
Thanks for clarification, this is what I expected but reverse image search wasn’t showing anything so figured I’d try here.
The 2nd image looks like a Type 95. The wheels don’t match the O-I and you can see the suspension rocker arm for the 3rd and 4 road wheel too.
Looks about right. I think the camera position being closer to the ground messes up the size perception to me, makes it look a lot larger than it actually is.
Apparently not. Toyota Super Cruiser is no longer in production
Cockpit door pressure relief valve lol
It looks like the Land Cruiser that was released in 2014 for a limited time.
The Land Cruiser J70 has been in production for close to 40 years, though received a styling refresh in the 2010s.
This vehicle meanwhile is custom-made.
Other than the cabin, which uses Toyota Land Cruiser J70 parts at least externally, the chassis, transmission, and engine are non-standard. The cabin is also different from production types due to internal armor plating.
