Text of the document
Below is the text to the declaration of the war with the boldened texts released in the name of the Emperor of Japan:
The document declares the war against the United States
and British Empire
, discusses their presumed disruptive actions against Empire of Japan's foreign policy and states that all avenues for averting war have been exhausted from the Government of Japan
. Japan had invaded much of East Asia to create what they called the "Greater East Asia Co-Prosperity Sphere
", now largely viewed as a pretext for imperialism. In response, the U.S. imposed a oil embargo
on Japan in August of 1941 to preserve their control in Asia and to contain their actions, which Japan saw as an unfriendly act and prompted it to retaliate with the bombing and declare war on the two countries.
