But I also know quite a few Japanese people in their early thirties, some of them very very very to the right of the political spectrum. Even to them Imperial Japan is sheer terror. Young kids being forced to commit suicide (kamikaze), endless suffering of the population, a crazy mentality, worshiping the emperor as a god, horrific experiments in the Chinese countryside, etc. My sample might be small, but I don't think there's much nostalgia of Imperial Japan anywhere in the Japanese population.
[1] Extra points if you can't even recognize Abe doing giving an interview on TV. And yes, that one has never missed an election. That's the most terrifying part to me. If you want to opt out of caring about politics, it's completely fine by me, but at least do it completely...
