Sort of.

In Japan most of the resistance was spent pretty quickly in the attempted coups, last post-surrender kamikaze missions, and some brief hold outs. However as the case was the surrender was made by the Japanese Emperor himself which undercut a lot of the legitimacy, or even arguably goals a resistance movement might have.

The German resistance certainly existed in the guise of the "Werewolf" organization. It was intended at first as a simple "stay behind" organization that would continue to operate in support of the German state in places occupied by the Western Allies/Soviet Union. However it was organized very late in the conflict, and in so many words it was recruiting from the pool of people left after the German Army, and Volkstrum already rolled through.

It had very little to operate on, the Allies and the Soviets both expected there to have been much more dramatic resistance to occupation so they were quite well prepared, and much of the German population had little desire to keep the war going.

Basically there's a single confirmed "werewolf" attack from during the war (the murder of the post-surrender mayor of Aachen) with some other attacks claimed, but of very doubtful legitimacy.

I am not aware of a Italian resistance movement outside of the rump-portion of the Fascist Italian state that continued to fight alongside the Germans.

If I had to make an assessment, the Germans and Japanese were both populations that had fought and heavily lost a total war, and much of the population was willing to accept occupation in exchange for some sort of return to normalcy (remember, both the Germans and Japanese were extensively bombed, and even basic items like food were in short supply). Further the ideology of resistance did not well survive the defeat, with the Emperor in Japan providing legitimacy to surrender, and the death/capture of much of the Nazi's main leadership leaving prospective Nazi resisters without leadership or focus.

Then finally in more physical terms, the Allies and Soviets were fairly well prepared for an insurgency, while the Germans and Japanese were not prepared to conduct one.
