Japanese land and air forces fighting alongside Britain

How would Japanese naval, army, and air forces fare against Germany if Japan joined Britain after the fall of France?

The army could fight in North Africa after an armour upgrade, aircraft could support that campaign, and ships could reinforce the Mediterranean and Atlantic.

The counterfactual sends Japanese army units to North Africa, where they would probably need upgraded armour. Army and navy aircraft could also serve in that theatre. Japanese ships would reinforce the Mediterranean and might support the Atlantic campaign. A pair of Kongos joining Hood and Prince of Wales against Bismarck and Prinz Eugen illustrates how Japanese fast capital ships could alter a specific encounter.
