With PODs no earlier than 1st September 1939, make Poland, Denmark, and Low Countries parts of present day Germany, Korea and Manchuria parts of present day Japan, and Libya part of present day Italy...
Its hard to have a pacifist Self Defense Force only Japan have Manchuria and Korea. Same goes for an anti-nazi Germany (or any Germany for that matter) having Denmark and the low countries... which were never really part of Greater Germany like Korea or Libya were to Japan and Italy respectively).
Still ill take a shot at two out of three.
Japan is defeated by the US as usual and the Soviets August Storm the crap out of the Japanese Army. The POD is that they dont turn Manchuria over to Mao for whatever reason and instead set up a Manchu People's Republic in accordance with the double shell plan. Cold War happens and the Soviets lose and collapse spectacularly like irl. Among other things so does the MPR. The new un communist Republic of Manchuria is to be a pretty bad wreck, tends to happen when a nation is a vassal of the Soviet Empire. In anycase the nation isnt invaded by China, even though they pretty much dont have the ability to put up a fight. Just roll with it. America and Europe are too busy gobbling up the new Eastern European nations into NATO and such to pay much attention to Manchuria. The economic powerhouse of the region Japan on the otherhand (developed as otl more or less) is rich, and ether the nation or a group of enterprising businessmen see opportunity and make several loans or investments into Manchuria, it helps that the local dictator is both able to keep a semblance of stability while being receptive to bribes from the Japanese. The end result, the Republic of Manchuria ends up as little than an extension of Japanese economic interests.
Italy also goes the same path it went down on irl. POD is that a genuine and vocal communist movement appears in Libya. However diplomatic blunder by the Soviets during one of the inter allies meetings of overstating how communist the Libyan group actually is. Unfortunately for Libya (or depending on your view point of how Gaffadi's rule has been irl, fortunately) the other allied nations believe some of it and see Libya as a possible hotbed of anti-colonialism and communism after its independence. Obviously not wanting that to spread to the rest of Africa, they justify Libya as being as Italian as Algeria is France, perhaps by making a few 'mistakes' in population figures, and allow Italy to keep Libya. Somehow they are able to keep it until the modern day.
Or you can just go the obvious route of having Italy not join ww2, but thats a bit cliche.
Both long shots i admit, but i had fun thinking of ideas.
As for Germany... like i said, hell if i know.
