As a user who has played Japan, I know for sure that Japan should not go to rank 5
The reasons are as follows
1. a poor tank
These two tanks are currently Japan’s highest rank equipment
The na-to is a tank without a turret, and because it is an open tower, it is vulnerable to destruction and lacks penetration, so it cannot penetrate American tanks
The chi-nu has turrets, but it lacks penetration, so it can only penetrate a portion of Sherman’s facade
And there are only a limited number of Japanese tanks that can be added later
These 3 tanks can be added to Japan (at least as far as I know)
But chi-to and chi-ri 2 lack penetration, so they can’t penetrate America’s jumbosherman or Pershing
The ho-ri has no turrets, so it’s less versatile and isn’t suitable for the Pacific (And it didn’t even exist.)
Japanese tanks also lag behind American tanks because they lack protection
On the other hand, if you look at American tanks
American tanks can easily defeat Japanese tanks, and the armor of American tanks cannot penetrate all Japanese tanks except ho-ri
As a result, American tanks are overwhelmingly superior to Japanese tanks, so Japan is no match for them
2. a poor anti-tank
Japan’s anti-tank is very weak
The current anti-tank weapons that Japan has are type-4 rocket launcher and type-5 rocket launcher
The type-4 rocket launcher has a low penetration force of 80 mm, making it very difficult to penetrate Sherman from the front
The type-5 rocket launcher has a slightly high penetration force of 100mm, but it is impossible to aim precisely because there is no sight
Also, 100mm of penetration is too small to deal with American tanks
Unfortunately, Japan has few other anti-tank weapons except for the two aforementioned anti-tank weapons
That means that Japan can’t defeat American tanks from a distance unless they use CAS by aircraft
This is a very serious problem and it will create a serious gap in Japan compared to the United States
conclusion
Other parts (aircraft, weapons, etc.) can be supplemented, but when it comes to tanks, Japan can’t be supplemented, and anti-tank weapons are not strong
Japan lags behind the U.S. in the anti-tank range, which is fatal to the game. Eventually, Japan will be far behind the U.S
This is already being seen despite Japan meeting the U.S. up to 4th rank
My suggestion is that Japan should not match more than 5 ranks
As I said earlier, Japan is no match for the United States above rank five. There are no infantry units, no aircraft, no tanks beyond the United States
So, as it is now, Japan should only meet up to rank 4 (or rank 3)
If the above is not resolved, Japan’s inferiority is clear and we can already see this
Japan should not go to rank 5 unless it adds good anti-tank weapons or tanks to deal with the United States
