Prince Naruhiko Higashikuni stepped in to manage the surrender of the Japanese Empire in 1945. This was handled quite effectively, but it soon became clear that he was not even remotely on the same page with the incoming US occupation forces about what should come next.
The elderly Kantaro Suzuki served as prime minister for the spring and summer of 1945, hoping to guide the nation through the final disastrous stages of the Pacific War.
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.
Imperial Army leader Hideki Tojo commanded the nation from 1941-1944. Once he decided to launch a total war against the Anglo-American Powers in December 1941, his own authority was tied to the success or failure on the battlefield.
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.
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. However, Nazi Germany’s rapid defeat of France soon undermined Yonai’s authority by convincing Japanese militarists that the nation was losing a historic opportunity for changing the international order.
For a short period in 1939-1940, little-known Imperial Army General Nobuyuki Abe took over leadership of the nation just as World War II broke out in Europe. Abe kept Japan out of the war but was unable to establish a firm political foundation for his government.
In 1939, rightwing ideologue Kiichiro Hiranuma came to power, but he refrained from attempting to institute any major policy changes. However, he soon presided over a series of disasters, each of which clearly indicated that Japan’s military-led foreign policy had miscalculated fundamental realities.
From 1937-1939, the nation was led by rightwing aristocrat Fumimaro Konoe, regarded by many as a man of destiny who might lead the nation to a glorious future. Konoe, however, proved to be a rudderless leader and soon allowed himself to be dragged into an all-out confrontation with nationalist forces in China.
With the selection in early 1937 of General Senjuro Hayashi to become prime minister, the Imperial Japanese Army was excited to have one of its own in charge of the nation for the first time in decades; but his first political moves alienated almost everyone and he was out within a few months.
