Japanese WWII turret traverse rates hardly appear in any documents. It makes me wonder if many of them are outdated estimates. Those few documented cases are a bit better than would fit into the pattern. Below is list of how they are in game.
vehicle - basic crew → aces
Chi-Ha 10.6 → 15.2 °/s *1
Chi-Ha Kai 10.5 → 15 °/s *2
Chi-Ha 12cm Short Gun 4.2 → 6 °/s
Chi-He 9.8 → 14 °/s
Ho-I 9.8 → 14 °/s *3
Chi-Nu 7.3 → 10.4 °/s *3
Chi-Nu II 11.5 → 16.5 °/s *6
Chi-To 8.9 → 12.7 °/s *4
Chi-To Late 8.9 → 12.7 °/s *5
Chi-Ri 8.4 → 12 °/s *4

Chi-Ha 57mm traverse I’ve found only from a lonely secondary source. It’s stated to have been staggering 30-35°/s.
-
Chi-Ha Kai was 400-500kg heavier than the basic Chi-Ha and most of that weight increase was in the turret. Electric traverse was already considered, but instead they added a second handwheel for commander to help traversing the turret. This feature was retained at least to Chi-Nu and likely to all the following vehicles.
-
Chi-Nu had an electric traverse system. American sources say the only difference to Ho-I was the gun, thus it implies Ho-I also had electric traverse. Both of them indeed have it in game. Unfortunately traverse rate isn’t listed.
-
Chi-To (prototype) and Chi-Ri also had electric traverse, which is documented to have been capable of traversing 360 degrees in 30 seconds = 12 °/s. One would expect Chi-Nu and Ho-I with their lighter turrets to have had similar traverse rate. Unfortunately this is not the case in game.
-
In game Chi-To Late (Chi-To’s planned production version) has electric traverse as well. It’s said the electric traverse was removed for simplification, though I haven’t seen the source for that. I guess WT developers chose to go this way, because manual traverse isn’t listed anywhere.
-
Chi-Nu II plans weren’t finished and traverse mechanism remains unknown. In game it has quite fast electric traverse.
In my view Chi-Nus are the oddest ones here. It is likely they used the same electric motor as Chi-To and Chi-Ri, but we can’t know how it would have been geared. I think 12-15 °/s would make sense for both of them.
Is there anything we could do to improve the situation? Perhaps there are still American documents or Japanese books we could try?

This is simply shortsighted. The M163 TVADS for instance can fill in an actual gap in rank 5 AA line for Japan before the Type 87. The M60 TIFCS is also pretty good addition to any 8.0 line up as well as the Commando Stingray (with the prototype Stingray in a Bulldog chassis as a premium or event). The V-150 armed with 90mm could also complement low tier Japan as a scouting light tank. Hell, the M90 ITV can give Japan a proper ATGM vehicle instead of the utterly useless Type 60 ATM.
Please actually look at the Thai vehicle subtree suggestion before saying stuff like this. Of course it doesnt add much to Japan top tier but I say its a positive that Japan’s top tier remains purely Japanese (aside from a potential Thai T-84 Oplot-T)

Wouldnt count on this. We only have a single image and a single source, unless we find more info on it, there would be no chance Gaijin would be adding this one
one image didnt mean that it will not be added
Not to be ‘that guy’ but… we can just get both.
Type 87 is currently 8.3. AWX (1978) is worse, but still likely to be 8.0 unless it loses the tracking radar (which still seems to be there, no search though). M163 is 7.3, and with the change from radar to passive tracking I could see it maybe go to 7.7 or stay at 7.3.
Either way that’s two new SPAAs that can be used as backups for existing ones, in future 7.7-8.0 lineups with Thai additions, or if the TVADS gets 7.3, a fantastic addition to the existing 7.3 lineup.

The prototype vehicles could fill all ranks.

There aren’t really enough Japanese prototype SPAA to guarantee a complete SPAA line. Maybe Type 94 (Type 2) in low tier but the Ta-Se already occupies 1.7, the Ta-Ha could maybe fit in between the Duster and SUB-I-II, AWX 1978 around 7.7-8.0, and CCV perhaps around 10.7-11.0 because of the APFSDS. There are a few left, but definitely not enough for “all ranks” as you say. Hence why Thailand can bring some new AA with MANPADS and TVADS to the tree.

Is it possible to has so high turret rotation speed with just man drive?

I didnt mean spaa only
Even an SPAA for 7.3-7.7?
Of course, but SPAA is just one example of why Japanese prototypes can’t fill ALL niches. Point being, Japan needed a subtree sooner or later, and Thailand in my eyes is a worthy candidate that has a lot to offer for most parts of the tree (although high tier and late mid tier to be sure).

The Ostwind II and the Zerstorer 45 have no pictures or even blueprints, just a written description
I already responded that it’s a good idea for the lower BR’s specifically where they are lacking
11.3-12.0 adding Thailand ground forces to that BR will make sure they don’t fix their own domestic equipment. Which mind you there’s tons of stuff missing there. The TKX and type 10 themselves have 6 variants between the 2 all of them very capable. Adding a T-84 to their top tier lineup incentivizes gaijin to not fix their equipment.

I probably did a mistake there. Chi-Ha and even Type 89 might have had two handwheels, but finding a proper source is a pain. It’s infuriating how few photos there are from inside these vehicles. I’ve been trying to look for a Japanese book for this.

we will introduce the performance of the prototypetype87 anti-aircraft gun.this vehicle was based on the body of the type61tank,and was equipped with a Japanese-developed enemy search and tracking radar in an all-round rotating turret.Teatswere conduced using the completed prototype vehicle,but the heavy weight of the turret meant that the type61tank could not demonstrate sufficient mobility.so it was decided to base it on the body of the type74tank.

I mean if you have documents supporting things like the second handwheel for the Chi-Ha Kai, and the reasoning for the Chi-Nu to have electrical-powered traverse, we can at least argue for a buff
7.3 BR and without a radar

In Chi-Ha Kai the handwheels were definitely there. Too bad most documents don’t bother to mention such detail or it’s in Japanese, so finding it from all the text is a pain.
In this photo the traverse mechanism itself is there on both sides, but gunner’s wheel is off.
9:30 and 11:30.
From I-Go and Chi-Ha there is even less, although they say this show was well researched.
Even Type 2 Ka-Mi had two horizontal traverse wheels.
Obviously manual traverse got too slow for what they wanted. The electric traverse is mentioned in multiple documents and it’s in game.
