Liberation Of Korea

The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be willing to mediate, the Soviets were covertly preparing to attack Japanese forces in Manchuria and Korea (in addition to South Sakhalin and the Kuril Islands) in fulfillment of promises they had secretly made to the United States and the United Kingdom at the Tehran and Yalta Conferences.

On 6 August 1945, at 8:15 AM local time, the United States detonated an atomic bomb over the Japanese city of Hiroshima. Sixteen hours later, American President Harry S. Truman called again for Japan's surrender, warning them to "expect a rain of ruin from the air, the like of which has never been seen on this earth." Late in the evening of 8 August 1945, in accordance with the Yalta agreements, but in violation of the Soviet–Japanese Neutrality Pact, the Soviet Union declared war on Japan, and soon after midnight on 9 August 1945, the Soviet Union invaded the Imperial Japanese puppet state of Manchukuo. Hours later, the United States dropped a second atomic bomb, this time on the Japanese city of Nagasaki. Following these events, Emperor Hirohito intervened and ordered the Supreme Council for the Direction of the War to accept the terms the Allies had set down in the Potsdam Declaration for ending the war. After several more days of behind-the-scenes negotiations and a failed ''coup d'état'', Emperor Hirohito gave a recorded radio address across the Empire on 15 August announcing the surrender of Japan to the Allies.

On 28 August, the occupation of Japan led by the Supreme Commander for the Allied Powers began. The surrender ceremony was held on 2 September, aboard the United States Navy battleship , at which officials from the Japanese government signed the Japanese Instrument of Surrender, thereby ending the hostilities. Allied civilians and military personnel alike celebrated V-J Day, the end of the war; however, isolated soldiers and personnel from Japan's far-flung forces throughout Asia and the Pacific refused to surrender for months and years afterwards, some even refusing into the 1970s. The role of the atomic bombings in Japan's unconditional surrender, and the ethics of the two attacks, is still debated. The state of war formally ended when the Treaty of San Francisco came into force on 28 April 1952. Four more years passed before Japan and the Soviet Union signed the Soviet–Japanese Joint Declaration of 1956, which formally brought an end to their state of war.

Background

By 1945, the Japanese had suffered a string of defeats for nearly two years in the South West Pacific, India, the Marianas campaign, and the Philippines campaign. In July 1944, following the loss of Saipan, General Hideki Tōjō was replaced as prime minister by General Kuniaki Koiso, who declared that the Philippines would be the site of the decisive battle. After the Japanese loss of the Philippines, Koiso in turn was replaced by Admiral Kantarō Suzuki. The Allies captured the nearby islands of Iwo Jima and Okinawa in the first half of 1945. Okinawa was to be a staging area for Operation Downfall, the Allied invasion of the Japanese Home Islands. Following Germany's defeat, the Soviet Union began quietly redeploying its battle-hardened forces from the European theatre to the Far East, in addition to about forty divisions that had been stationed there since 1941, as a counterbalance to the million-strong Kwantung Army.

The Allied submarine campaign and the mining of Japanese coastal waters had largely destroyed the Japanese merchant fleet. With few natural resources, Japan was dependent on raw materials, particularly oil, imported from Manchuria and other parts of the East Asian mainland, and from the conquered territory in the Dutch East Indies. The destruction of the Japanese merchant fleet, combined with the strategic bombing of Japanese industry, had wrecked Japan's war economy. Production of coal, iron, steel, rubber, and other vital supplies was only a fraction of that before the war.

As a result of the losses it had suffered, the Imperial Japanese Navy (IJN) had ceased to be an effective fighting force. Following a series of raids on the Japanese shipyard at Kure, the only major warships in somewhat fighting order were six aircraft carriers, four cruisers, and one battleship, of which many were heavily damaged and none could be fueled adequately. Although 19 destroyers and 38 submarines were still operational, their use was also limited by the lack of fuel..

Defense preparations

Faced with the prospect of an invasion of the Home Islands, starting with Kyūshū, and the prospect of a Soviet invasion of Manchuria—Japan's last source of natural resources—the War Journal of the Imperial Headquarters concluded in 1944:

As a final attempt to stop the Allied advances, the Japanese Imperial High Command planned an all-out defense of Kyūshū codenamed Operation Ketsugō. This was to be a radical departure from the defense in depth plans used in the invasions of Peleliu, Iwo Jima, and Okinawa. Instead, everything was staked on the beachhead; more than 3,000 kamikazes would be sent to attack the amphibious transports before troops and cargo were disembarked on the beach.

If this did not drive the Allies away, they planned to send another 3,500 kamikazes along with 5,000 ''Shin'yō'' suicide motorboats and the remaining destroyers and submarines—"the last of the Navy's operating fleet"—to the beach. If the Allies had fought through this and successfully landed on Kyūshū, 3,000 planes would have been left to defend the remaining islands, although Kyūshū would be "defended to the last" regardless. The strategy of making a last stand at Kyūshū was based on the assumption of continued Soviet neutrality.

Supreme Council for the Direction of the War

Japanese policy-making centered on the Supreme Council for the Direction of the War (created in 1944 by earlier Prime Minister Kuniaki Koiso), the so-called "Big Six"—the Prime Minister, Minister of Foreign Affairs, Minister of the Army, Minister of the Navy, Chief of the Army General Staff, and Chief of the Navy General Staff. At the formation of the Suzuki government in April 1945, the council's membership consisted of:

* Prime Minister: Admiral Kantarō Suzuki
* Minister of Foreign Affairs: Shigenori Tōgō
* Minister of the Army: General Korechika Anami
* Minister of the Navy: Admiral Mitsumasa Yonai
* Chief of the Army General Staff: General Yoshijirō Umezu
* Chief of the Navy General Staff: Admiral Koshirō Oikawa (later replaced by Admiral Soemu Toyoda)

All of these positions were nominally appointed by the Emperor and their holders were answerable directly to him. Nevertheless, Japanese civil law from 1936 required that the Army and Navy ministers had to be active duty flag officers from those respective services while Japanese military law from long before that time prohibited serving officers from accepting political offices without first obtaining permission from their respective service headquarters which, if and when granted, could be rescinded at any time. Thus, the Japanese Army and Navy effectively held a legal right to nominate (or refuse to nominate) their respective ministers, in addition to the effective right to order their respective ministers to resign their posts.

Strict constitutional convention dictated (as it technically still does today) that a prospective Prime Minister could not assume the premiership, nor could an incumbent Prime Minister remain in office, if he could not fill all of the cabinet posts. Thus, the Army and Navy could prevent the formation of undesirable governments, or by resignation bring about the collapse of an existing government.

Emperor Hirohito and Lord Keeper of the Privy Seal Kōichi Kido also were present at some meetings, following the Emperor's wishes. As Iris Chang reports, "... the Japanese deliberately destroyed, hid or falsified most of their secret wartime documents before General MacArthur arrived."

Japanese leadership divisions

For the most part, Suzuki's military-dominated cabinet favored continuing the war. For the Japanese, surrender was unthinkable—Japan had never been successfully invaded or lost a war in its history. Only Mitsumasa Yonai, the Navy minister, was known to desire an early end to the war. According to historian Richard B. Frank
