Factional rivalry and professional competence coexisted in Japan

Did factionalism prevent Japanese Army and Navy leaders from doing their jobs before 1941?

Japan was heavily factionalised, yet officials could still perform their duties with a high degree of professionalism despite intense personal and inter-service hostility.

Factional conflict did not amount to simple administrative paralysis. Japanese leaders could carry out their jobs professionally even while their factions despised one another. Competent work can coexist with destructive institutional incentives. The separate Army and Navy auxiliary-carrier programmes show one concrete cost: both services recognised overlapping needs but consumed scarce capacity through duplicated efforts. The useful question is where rivalry distorted priorities and coordination, rather than whether every participant lacked competence.
