actually...1940s Japan is what a redneck fascism would look like in this country. The officers in the IJA were not the best and brightest and their prescriptions were always might makes right.
The IJN was terrified of the Army's hotheads and were a bastion of liberality in comparison but their concerns about the Army were such that they withheld information about battlefield losses (e.g., Midway) from the Army to save face.
