Japanese declaration of war on the United States and the British Empire

The declaration of war by the Empire of Japan on the United States and the British Empire () was published on December 8, 1941 (Japan time; December 7 in the United States), 7.5 hours after Japanese forces started an attack on the United States naval base at Pearl Harbor and attacks on British forces in Malaya, Singapore, and Hong Kong. The declaration of war was printed on the front page of all Japanese newspapers' evening editions on December 8. The document was subsequently printed again on the eighth day of each month throughout the war (until Japan surrendered in 1945), to re-affirm the resolve for the war.

Historical context.
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 an oil embargo on Japan in August 1941 to stop aiding their aggression in Asia and to contain Japanese actions such as their war crimes in Nanking. There was also an embargo on steel. Japan saw this as a hostile and provocative act, and retaliated with the bombing of Pearl Harbor and the declarations of war on the US and the British Empire.
