After using nuclear bombs on Hiroshima and Nagasaki Japan Surrendered. As fellow victors the USSR where allowed to occupy Japan north of the 38th parallel. The Soviet set up the Japanese Democratic Peoples Republic (JDPR), led by the 1st premier Sanzō Nosaka. Sendai was made the republic's capital. In addition to controlling everything north of the 38th parallel, the Soviets would give their new client state the Northern portion of Sakhalin Island. The occupation lasted until 1948 when the 16th Army withdrew. During the late forties, Imperial Japan deported many communist and those accused of holding communist sympathies and also Koreans in the south to the JDPR. Nosaka's reign was characterized as Stalinesque. He purged many of his supposed enemies, putting them in prison and took steps to make sure the army only answered to him and that he was the state and his will the law.
On June 25th, 1950, North Korea invaded its Southern counterpart, and the first war between the 1st and 2nd world started. To everyone surprise, Nosaka decided to split from his Soviet overlords. During the early hours of July 1st, 1950, Nosaka ordered the arrest of all Soviet citizens within his country calling them enemies of the people.
The shock of Nosaka's action led the Soviets to plan an invasion, and the Soviets 25th was spotted on the other side the Straits of Tartary this would lead to the North-South rapprochement and both Japans entered the war against the North Koreans. Not wanting a direct war with the USA, the Soviets pulled back but sent increased aid to their satellite.
JDPR kept much of their military at home but sent 30000 men to fight in the peninsula along with money and materials, the South Japanese, on the other hand, sent 300000 men to the peninsula over the course of the war. The war would rage for over 4 years, despite the Communist Chinese entry into the war, The UN coalition managed to push back the communists, and on January 18th, 1955 and ceasefire was agreed upon. The Korean war turned cold and while no peace treaty has been signed general peace stands, and the border between both nations is the most heavily militarised in the world.
The South Koreans and gained territory and most importantly took and kept Pyongyang. the agreed-upon border from the ceasefire was the stagnant front, going from Anju south of the river Chongchon to the Taedong River, up the Taedong till Yonggwang, then to Hamhung then to Samho until the sea of Japan.
The war had a huge impact on the Japans, US investment in both countries saw a huge economic boom during and after the war. Also, Nosaka Democratised the country and Liberalised the economy while keeping socialized education, healthcare, maternity and welfare programs, transitioning from a communist dictatorship to a social democracy. In the end, this would come to an end on April 1955, when the North Japanese were given the choice between continues independence or reunification with their southern brethren in a referendum. 99.97% of North Japanese voted for reunification and Nosaka stepped down and Premier and retired from politics. After reunification, a new constitution was written incorporating many of Nosaka's social programs. While the Soviets made many complaints about the whole affair and demanded that a unified Japan be demilitarised, they were mostly ignored by their western counterparts.
The Japanese affair which it has come to be known as in the former USSR and her satellites had a lasting effect. When the Hungarian Revolution started in 1956, the USSR responded heavy-handedly setting the precedent. The Soviets tightened their grip on the Warsaw pact, starting a near 4 decade-long campaign of fear and surveillance never seen before until it collapsed.
Today Japan is a nation of 151 million people. It has the second largest economy in the world, 4th most powerful country in military capability. The 20th Century for Japan had seen it rise, fall and its ultimate rebirth into one of the most technologically advanced and envied nations in the world.
Korea has also done very well for itself, after the war and many military coups, the country finally got on its feet and emulated its eastern neighbor in success. It has a population of 62 million, 10th largest economy, 3rd largest and 5th most capable military in the world.
The Korean had a huge impact on the USA, it helped united the public against the red threat, but it also changed the way they viewed communists. The Japanese affair showed the US public that communist states can be turned into democracies if approached right. It also led to the stereotype that every communist leader could be bought out for a good price if the Soviet influence in a nation was low enough.
