Last time we spoke about the Siege of Japan. In the summer of 1945, Japan faced its most devastating siege. A pivotal component was the aerial mining campaign entitled "Starvation," masterminded by General Curtis LeMay. B-29 Superfortress bombers were deployed to lay mines in critical waterways, cutting off resources and crippling Japan’s industrial capabilities. This silent assault inflicted chaos on Japan’s shipping lanes, sinking over 670 vessels and significantly disrupting supply lines. Amid this turmoil, the Allies intensified their firebombing campaigns, targeting urban centers like Tokyo, Osaka, and Kobe, leading to extensive devastation and loss of life. By August, Japan's civilian and military morale crumbled under the weight of destruction. The climax of this siege came with the atomic bombing of Hiroshima, which unleashed unparalleled destruction. As Japan’s leadership struggled for options, the nation was effectively brought to its knees. The relentless siege had achieved its goal, Japan was irrevocably broken, marking a profound moment in history.

Hello there, again like in the previous episode, this one is just going to state what happened, I am not going to delve into the why’s just yet. I am currently writing an entire special episode on why exactly Japan surrendered, focused on the actions of Emperor Hirohito, who I will argue prolonged the 15 year war to protect the Kokutai. So a bit of a spoiler there I guess. 

The worst has come to pass for the Japanese Empire. An atomic bomb has fallen, devastating an entire city. In a blinding flash, over 140,000 lives were lost or forever altered. But this was merely the beginning. The Americans were poised to unleash destruction from the skies, a scale of devastation never before witnessed on this planet. The choices were grim: surrender or complete annihilation.The Japanese faced not only this overwhelming threat but also another peril. The Soviet Union prepared to invade Manchuria and other crucial territories within its reach.

As we last left off, the Americans had been conducting a prolonged and devastating air and naval siege of the Japanese Home Islands in preparation for the invasion of Kyushu. This campaign culminated in the atomic bombing of Hiroshima on August 6, reducing the once-great city to ruins and leaving a staggering casualty toll that would forever haunt the Japanese people. Survivor accounts recount the haunting experience of wandering through the destruction, disoriented and unsure of where to go. They spoke of hearing the desperate cries of those trapped beneath crushed buildings or suffering from horrific burns. As small fires ignited by the blast began to spread, they coalesced into a firestorm that surged through the rubble, claiming the lives of many still trapped inside. Frightened residents jumped into the rivers of Hiroshima, only to drown in their desperate attempts to escape the flames. Over 90% of the doctors and 93% of the nurses in Hiroshima perished or were injured, and most hospitals were either destroyed or heavily damaged. By early afternoon, police and volunteers worked tirelessly to establish evacuation centers at hospitals, schools, and tram stations. Yet, tragically, many would die before receiving aid, leaving behind grim rings of corpses around these facilities. Some survivors who initially appeared unharmed would succumb within hours or days to what would later be identified as radiation sickness. Most members of General Hata’s 2nd General Army headquarters were undergoing physical training on the grounds of Hiroshima Castle, barely 900 yards from the hypocenter. As a result, 3,243 troops lost their lives on the parade ground. Miraculously, Hata himself survived the explosion with only minor injuries, but many of his staff were not so fortunate, including Lieutenant-Colonel Yi U, a prince of the Korean imperial family, who was killed or fatally wounded.

In total, the 2nd General Army, 59th Army, 5th Division, and other combat units in the city lost an estimated 20,000 troops. Survivors regrouped at the Ujina Air Base on the outskirts of Hiroshima, where they organized relief efforts and maintained public order once martial law was declared. With Mayor Awaya Senkichi killed at the mayoral residence, Hata assumed control of the city’s administration and coordinated relief efforts. The initial reaction of the Japanese government to the devastation in Hiroshima was mixed. The Imperial Japanese Army and Imperial Japanese Navy military leadership received only fragmentary reports about the tragedy, as communications with Hiroshima had been severed. Meanwhile, American and British radio broadcasts promptly informed ordinary Japanese civilians and their government about the atomic bomb attack on August 7.

The following day, Tokyo issued a press release confirming the bombing of Hiroshima, but it notably did not state that the United States had dropped an atomic weapon. After technical teams visited the site of the bombing, they concluded that the enemy B-29s had indeed used a nuclear device. At this juncture, the diplomatic situation within Japan was chaotic. Many members of the Japanese cabinet believed that surrender was the only viable option, while others, particularly military figures like Hata, were determined to continue the fight. Looking back, between July 17 and August 2, Soviet leader Joseph Stalin, British Prime Minister Winston Churchill, and U.S. President Harry Truman convened in Potsdam to negotiate terms for the end of World War II. The Potsdam Conference is perhaps best known for President Truman’s conversation with Soviet leader Joseph Stalin on July 24, during which Truman informed Stalin that the United States had successfully detonated the first atomic bomb on July 16. Prior to leaving for the conference, a top-level civilian Interim Committee, led by Secretary of War Henry Stimson, suggested that Truman inform Stalin about America’s new nuclear capability. This was intended to prevent the Soviets from learning about the bomb through leaked information, and Truman agreed to share this news. Historians have often interpreted Truman’s somewhat firm stance during negotiations as a reflection of the U.S. negotiating team’s belief that their nuclear capability would enhance their bargaining power. However, Stalin was already well-informed about the American nuclear program, courtesy of the Soviet intelligence network. This understanding enabled him to hold firm in his positions, complicating the negotiations. In the end, the leaders of the United States, Great Britain, and the Soviet Union, despite their differences, remained allied throughout the war. However, they would never meet again collectively to discuss cooperation in postwar reconstruction. One of the critical topics discussed was how to handle Japan. During the conference, Truman sought and received Stalin's final assurance of entering the war on August 9, in accordance with the agreements made among the Allies during the Yalta Conference in February 1945.

On April 5, Soviet Foreign Minister Vyacheslav Molotov informed Tokyo of the Soviet Union's unilateral abrogation of the Soviet-Japanese Neutrality Pact. He assured Japan that the treaty would remain in effect until April 1946, even though the Soviets were already planning an offensive in the Far East. A Soviet invasion would prove beneficial for the Americans, as it could prevent the movement of hostile troops from Manchuria, Korea, and North China to the Home Islands of Japan before an invasion of Kyushu was launched. On July 26, the United States, Great Britain, and China released a declaration demanding Japan's immediate surrender. The declaration called for the dismemberment of Japan's remaining empire, the demobilization of all military forces, trials for war criminals, and the elimination of Japan's capacity for future belligerence. While the declaration did not alter the requirement for unconditional surrender, critically it left ambiguous how the Japanese people might shape their future government, as it did not specify a direct end to or continuation of the imperial dynasty. The crux of that matter was the preservation of the Kokutai.

The Kokutai was the national essence of Japan. It was all aspects of Japanese polity, derived from history, tradition and customs all focused around the cult of the Emperor. The government run by politicians was secondary, at any given time the kokutai was the belief the Emperor could come in and directly rule. If you are confused, dont worry, I am too haha. Its confusing. The Meiji constitution was extremely ambiguous. It dictated a form of constitutional monarchy with the kokutai sovereign emperor and the “seitai” that being the actual government. Basically on paper the government runs things, but the feeling of the Japanese people was that the wishes of the emperor should be followed. Thus the kokutai was like an extra-judicial structure built into the constitution without real legal framework, its a nightmare I know. Let me make an example, most of you are American
