Why Japan could not solve its wartime production gap

Would the Second World War have changed if Japan's army or navy had taken firmer control of the government?

The conduct might change, but the decisive production and logistics imbalance would remain.

An army-led Japan might fight more stubbornly, while a navy-led government might seek a different settlement. Neither arrangement changes the material balance that shaped the war. Britain and the United States both possessed deeper shipbuilding, industrial, infrastructure, and global-support capacity than Japan could match. A shift in service control might alter the conduct or ending of the conflict without curing the production and logistics gap that made victory unattainable.
