A simpler Japanese force design for Midway

One proposed alternative groups Japan into a concentrated northern force, a heavily escorted Midway strike force, and an amphibious force following behind instead of operating off to one side. This structure would reduce coordination burdens and give the fast carrier force the protection needed to fight an unexpected fleet action. Keeping the slower invasion echelon behind the striking force would preserve its schedule without asking it to provide immediate protection. The alternative retains Japan's two strategic threats while giving each operational group clearer tasks and better mutual support. Whether Japan expected an immediate fleet battle remains uncertain, since formal documents can differ from commanders' private expectations.
