Kuniaki Koiso and the Inescapable Slide Toward Defeat

Imperial Army officer Kuniaki Koiso became prime minister well after Japan’s position in the Pacific War had already become hopeless. It took him months to reach this understanding personally, and when he ultimately came to realize that his own ability to command the situation was also close to zero, he stepped down.

Hideki Tojo and the Option for Total War

When Fumimaro Konoe returned to the premiership in mid-1940, he launched a bolder package of policy initiatives, including the declaration of the Greater East Asia Co-Prosperity Sphere and the creation of a one-party state.

Mitsumasa Yonai and the Fading Prospects for Peace

In early 1940, moderate Navy Admiral Mitsumasa Yonai was selected by Emperor Hirohito in a final effort to head off military conflict with the Anglo-American powers.
