How stable was Japanese naval leadership, and did assassination threats repeatedly disrupt doctrine?
Short answerLeadership was relatively stable; political violence had an effect, but it did not repeatedly transform naval doctrine or philosophy.
NotesThe chief-of-staff position was comparatively stable despite the political turbulence around it. Yonai and a senior prince remained central figures for long periods, and a Navy minister even moved into the premiership. Assassination attempts mattered, but they did not constantly change naval doctrine or philosophy. The violence of interwar Japanese politics therefore does not by itself prove repeated institutional turnover within the navy.
