Chiefs of Staff of the Axis Navies: (Long Patrol) - P9/14: Shigetarō Shimada

The opening distinguishes officers who opposed the war yet continued to serve from Shimada, whose conduct receives far less sympathy.

Shimada's rise from Navy Minister to chief of the naval staff is set against deep distrust from fellow officers and his rivalry with Osami Nagano.

Shimada approved the Pearl Harbor plans as Navy Minister, then combined that office with the naval staff leadership in an unusually concentrated command role.

Concentrated naval command requires strategic judgement, political skill, and a durable institutional base, qualities Shimada did not bring together.

Shimada's cruiser and battleship service, staff appointments, and War College success did not establish the standing expected of a supreme commander.

Shimada used Japan's losses to challenge Nagano and promised to keep fighting without dependable Axis partners. The criticism of his results includes a misplaced Leyte Gulf example.

With Tojo directing the army and Shimada positioned as his naval counterpart, the Japanese war effort still failed to achieve the coordination their offices appeared to permit.

Holding both the ministry and naval staff leadership forms the basis of the argument that Shimada could no longer shift responsibility between the two offices.

Shimada received a life sentence for waging aggressive war and was paroled in 1955. Tojo apparently sought marshal-admiral status for him several times, but Hirohito refused.

Even the specialist book used for this video contains little material on Shimada, which limits how detailed the biography can be.
