Actually, it's the first time. And I apologize, the correct term for what you are describing is fascism.

Nazi Germany believed in the supremacy of the aryan race, and your claim that an island state is superior to 50% of the world by area is about the same. It's also tone deaf, considering their past alliances and how hard they worked to distance themselves from that past.

There's much to like about Japanese culture, but please keep in mind that the same culture also gave birth to the Yakuza and whatever you want to call this:
