WI: Japan fights with the allies in WW2

Inspired by the movie "2009: Lost Memories:" were a Japanesetime traveller from our time goes back and changes events to favour Japan.. which turns out to be:


 
I don't think World War II would last 8 years. Germany would face the full force of the allies, including a powerful Japan. There would have been an earlier Manhatten Project.
 
One not-so-minor problem with any alliance between the US and Japan is going to be the division of the Pacific ocean. I'm not saying that agreements couldn't be reached, but settling who gets what is going to be some really intricate (and interesting) geopolitical waltzing.

If such an alliance did come to pass, I'm not sure how much it would shorten World War II. After all, you can only kill things so dead. Face it, having Kido Butai and the Yamato twins supporting the D-Day landings would have made life really miserable for anything downrange, but would it really have changed or accelerated the outcome of the operation significantly?

The biggest likely change would be (as far as I can tell) that the Russians might do a bit better against the Germans, since in this timeline they can throw manpower from their Eastern front against the Germans.

I also don't think you'd see the atom bomb dropped on Berlin (or at all). It can't be developed much faster without some major alterations to history, and wouldn't really be needed. By the time the atomic bomb was ready (July 1945), the Germans were already defeated (May 8, 1945) in our timeline. In this timeline, the Germans won't do as well, so you need to cut (probably) six months to a year off the atomic bomb's development time. After all, if it's obvious that Berlin will fall *without* the use of nuclear weapons, I can't see the US just blowing up the city for fun.
 
If Japan was a major victor in WW2 (instead of China which would be a province of Japan in this timeline) why did it take 15 years for Japan to get on the security council assuming it was formed in 1946?
 
So Japan in the 30's is more friendly to the Allies and no war in China. Maybe, just maybe, this leads to an expanded Operation Pike just before the German Ardennes offensive, with Allied bombers striking Baku and Grozny and Japanese forces attacking Soviet positions in the east. Then France falls, the Soviets stop Japanese advances (maybe they loose North Sahalin in the process, maybe Vladivostok as well at most) and the bombing raids against the Soviet Caucasus peter out, as AA defences and fghters ar massed in the area. After that, some kind of truce is reached as no side has any actual interest to fight the other.

Major changes could take place in the Med if the Japanese delpoy part of their navy there.
 
What should be interesting is if we can make a realistic version of the 2009 Lost Memories timeline, minus the ASB and anachorisms.
