Which Imperial Court factions did the Japanese commanders belong to?
Short answerTheir alignments were fragmented: Ijuin was linked to Prince Fushimi's circle, Osugi to more aggressive prowar elements, and Omori to Yamamoto's group.
NotesImperial Japanese Navy factions were too splintered for a simple east-court versus west-court classification. Matsuji Ijuin is associated with Prince Fushimi Hiroyasu's circle, while Morikazu Osugi stood closer to factions willing to continue an aggressive war. Sentaro Omori is placed with Isoroku Yamamoto's group. These divided affiliations add political context to an operational command already burdened by overlapping rank and weak cohesion.
