Japanese Civil War (From Sea to Shining Sea)

The Japanese Civil War was fought for nearly six years between the Imperial Government and communists in Japan. It is described as "the fire that started the Cold War".

Prelude
Following the end of World War 2 in 1945, tensions between the Japanese people and their emperor began to surface. The Japanese Communist Party began to gain influence with the people, and was funded by America. On October 8, 1947, Emperor Hirohito was captured and promptly executed by communists, beginning the civil war.

Outbreak of war
Following the emperor's death, he was posthumously renamed "Shōwa", and his son Akihito was made emperor of Japan. The Japanese military was sent to execute communists. The Japanese Communist Party fought back, forming the Japanese People's Army, with Kyoto serving as the military's headquarters. The American Navy was sent to capture Tokyo, but failed. The Japanese People's Army quickly invaded the south, capturing Shikoku and Kyushu by November of 1948. Western Honshu was captured by communist forces, while Eastern Honshu remained under imperial control. China and Russia nullified their declarations of war on the Japanese Empire and supplied resources to the imperial government. America, however, gave far more support for communist revolutionaries. With a communist revolt succeeding in Hokkaido, leading to an invasion Northern Honshu. With defeat inevitable, the Royal Family, along with the 373 members of the Imperial Diet and 860 citizens escaped to Saishū island, renaming it New Japan. Remaining imperial forces were defeated on September 1, 1953. Although a peace treaty was never signed, fighting between the 2 forces ended, bringing an end to the war.

Aftermath
Although the Japanese Empire had fallen, its territory remained under Japanese control. Communist regimes were established in Japanese territories, creating the "Asian Socialist Pact" between Japan and its satellite nations. Nosaka proclaimed the "Democratic People's Republic of Japan" with Tokyo as its capital. Despite intending to join America as the 51st of its "republics", Nosaka announced Japan would remain independent, causing the American-Japanese Split. Japan agreed to join America in an alliance known as the "Communist League", though the development of "全自立" in Japan weakened this alliance. New Japan remained allies with China and Russia, which supplied economic and military support for the new nation.
