True wasn’t specific enough on duration, not sure about Japan as I think it was always a militaristic govt.
As in there was never a democracy that led to militaristic autocracy based on economic conditions, could be wrong
Japan had a form of a normal parliamentary democracy, albeit with explicit constitutional roles for the military, and the emperor was much more than a constitutional monarch. Japan had political parties and cabinet government, mostly civilian, plus universal suffrage.
But the political crises of the 30’s changed that radically, de facto if not de jure. The civilian parties lost power in both a formal and informal sense. There was civil unrest and the military was afraid of socialists abd communists rising. The 1931 Manchurian annexation was a sort of “unauthorized” wag-the-dog exercise that worked to distract the public.
Of course, all this had severe consequences down the road. Japan had fallen into the proverbial hole, and it kept digging.
And so on. Its an interesting story.
