Welcome again to my how to be faq guides. Now about my Germany faq guide is still going thru a process if attacking Germany first is a good idea.
Anywho lets get to Japan. My favorite country. (as you can tell from my Username.) The reason why I like Japan is because I think they are the sences of the Axis rather Germany is the Brain. Japan is like US because they don't give up. The reason why the US never loses any war (except 1 or 2).
1) Attack US. Attacking the US will neutralize the advancement on Germany.
2) Occupy US. Occupying the US will make Japan have more money and will make Japan have alot more land.
3) Attack Russia. Now if you read my first faq guide about Germany, you will know that the Germany will attack Russia about this time as well. Attack just the Eastern side and some of the central, Germany will everything else.
4) Reinforcements. Reinforce Germany when you have to. Occupy more countries and just attack when needed.
5) Now You basically won.
