"The Japanese are good at imitating other people, but lack the ability to create new stuff" is an old, old, bit of racist horseshit. Drop it.
The Japanese simply didn't have a big enough economy -yet - or enough trained scientists - yet - to build a bomb. Same thing with, say, Italy. But the scientists and engineers they _did_ have compared quite favorably with ones anywhere else in the world. If a Japan which had stayed out of WWII had decided it really, really wanted the bomb it almost certainly would have it before 1960. If such technological titans as Maoist China and Idira Ghandi's India could build the bomb, the Japanese certainly could do so.
As for the scenario: you can't get the Japanese to pull out of China in 1941 with a 1941 POD, the military were just too committed to some sort of victory and would never stand for the loss of face. You can have an _earlier_ POD: say, an assasination of Chiang Kai-Shek, leading to a fresh outbreak of Chinese civil war. Perhaps a brief Japanese intervention to prevent the Communists from consolidating their position in the north, and a withdrawl in 1941 as chaos deepens. As long as the Chinese keep fighting each other, the Japanese have nothing to worry about...

As for a couple of other points raised:
a US-German war even sans Pearl harbour is likely: there was pretty much an undeclared naval war going on by late 1941, thank to US lend-lease, which could easily boil over into actual warfare if Hitler wasn't very cautious - and that's not really typical of Hitler in 1941...
Hard to say what happens in China. If the Japanese play a good game of playing local rulers off against eachother, and supporting anti-Communist warlords when the Communists get too strong, there's a good chance they can keep China divided for a long time - if nobody interferes. However, the US, fresh from a victory against the fascists, will not be happy with such blatant interference in Chinese affairs, and will bring pressure against the Japanese.
Probably economic rather than military, though: the Cold war will be getting started, and the Japanese look like potential allies against the Soviets: the Japanese, meanwhile, can argue they are working to keep the Communists out of China. Stalin will probaby be very critical, but facing off with the US in central Europe, he's unlikely to start another war as long as Japan isn't getting much benefit out of it's meddling in China, and a weak, divided China is not something Stalin will particularly mind.
Will have to think on this a while longer. China will almost certainly be united by _someone_ eventually, but when this will happen, and whether this someone will be a communist, a hard-leftist of a different stripe, or a right-wing type is hard to say. Does Japan decide it can affort to let China go to hell it's own way? Does it intervene militarily to prevent a Communist takeover, perhaps with some US support? (Potentially very nasty for the Japanese, especially with the USSR smuggling tons of weapons over that thousands of miles long border) Does it try to sponsor a "friendly" warlord for the top spot?
There will not be a three-sided cold war, at least not at first: the Japanese are not strong enough to be a third player, and need trade and raw materials from the West and their colonies. Their economy in WWII was really hardly bigger than Italy's, although they made much better use of what they had. Even if the Japanese are fairly successful in modernizing their territories and don't lose Manchuria to a reunited China, they're unlikely to be in a position to compete with the big boys till the 1970's at least, and that's if the Japanese don't end up being undermined econmically by bleeding sores of colonial revolt or the suggested fresh swing into the Chinese quagmire to prevent a Communist takeover.
Cold war may be milder than OTL, and the US may miss out on Mcarthyism: no Korean war, and if China is "lost" by anyone, it will be by the Japanese. Also, Vietnam is quite likely avoided by the US: without the Japanese occupation, Vichy forces remain in control, and the Communists don't have the opportunities afforded by the chaos of war and it's aftermath. The French, however, won't be able to hold onto the place in the long run: they will face a nasty insurgence even without the territorial base the Vietmihn held in 1945, and colonialsm is on the way out even without the Japanese humiliation of European colonialists. At best they will be able to impose a semi-friendly government and get out semi-gracefully, at worst they will be driven out. A US less fixated on East Asia probably won't care, and will probably lack a seperate "south Vietnam" to support anyway.
Hmm - thought - the Japanese join the Allies in declaring war on the Germans as soon as it is clear the D-day landings have succeeded, so they can get a place at the victor's table...if there is a UN established, will there even _be_ a security council? It was OTL a "victors club" of WWII, but in this TL one of the "victorious" big powers is a late arrival which didn't do much to beat the Nazis, and looks a bit fascistic itself.
