The problem is we only have 1 eary japanese plane, the A6m2, and only have 2 mid-era Japanese planes, the A6m5 and the Ki61. We also only have 2 late-era Japanese planes, the N1k2 and the Ki84.
That's a pretty sad and pathetic lineup to match against half a dozen different spitfires, p40B and E, 4 different F4us, 2 F4F types, an F6F, P38s, P51s, heavy bombers, etc etc etc.
The Japanese planeset if very limited in this game, which makes such setups hard to pull off.
