On September 11, 1945, police surrounded the modest house in Setagaya, Tokyo. A muffled gunshot echoed from inside, and when they broke in, they found General Hideki Tojo bleeding from a self-inflicted gunshot wound to the chest. He had aimed at a charcoal mark a doctor had drawn over his heart, but the bullet missed. American medics rushed him to a military hospital, pumping him full of blood donated by US soldiers to save his life.
They needed him alive. The victors wanted their trial. The war that Tojo had helped launch was over by then. Tokyo lay in ruins, firebombing had reduced entire districts to ash, and millions of people had fled the capital or died in it.
When Emperor Hirohito announced Japan’s surrender on August 15th, 1945, the first radio broadcast most Japanese citizens had ever heard from their god-like emperor, he spoke in archaic court language that many could barely understand. But the meaning was clear. Japan had accepted the Potsdam Declaration, which demanded unconditional surrender, demilitarization, and the punishment of war criminals. General Douglas MacArthur, the Supreme Commander for the Allied Powers, landed at Atsugi Airfield at the end of August, striding down the ramp without a sidearm, a calculated gesture of confidence.
His task was monumental: occupy a nation of 70 million people, transform its political system, try its leaders for war crimes, and prevent the country from collapsing into chaos or communism. Arrest orders came swiftly. MacArthur ordered the apprehension of approximately 100 suspected war criminals. Tojo was among the first.
As he bled on that September morning, two Japanese reporters recorded his words: “The Greater East Asia War was justified and righteous. I am very sorry for the nation and all the races of the Greater Asiatic Powers. I wait for the righteous judgment of history. ”
But the most consequential decision MacArthur made was about who would not be arrested: Emperor Hirohito.
Australia, Britain, and American polls showed that 70% of the US public wanted Hirohito tried as a war criminal. He had been the head of state throughout the entire period of Japanese aggression. His signature appeared on the declaration of war against the United States. His approval had been required for every major military operation.
Critics argued that trying Tojo while sparing Hirohito was like trying Hitler’s generals while letting Hitler go free. MacArthur saw things differently. Without Hirohito, he feared Japan might descend into chaos, guerrilla resistance, or communist revolution. The Japanese people who had been taught to revere the emperor as a living god might never accept reforms imposed by foreign occupiers who had destroyed their divine sovereign.
On September 27th, 1945, the emperor made an unprecedented visit to the American Embassy to meet MacArthur. The photograph from that meeting became one of the most famous images in Japanese history: the tall, casual American general in his open-collared uniform towering over the diminutive emperor in formal morning dress. The message was clear about who held power now, but the meeting also signaled that Hirohito would be protected. Behind the scenes, MacArthur’s staff worked systematically to ensure that the emperor would not be implicated in the upcoming trials.
Brigadier General Bonner Fellers worked to protect Hirohito from the role he had played during the war, allowing major criminal suspects to coordinate their stories so that the emperor would be spared from indictment. The strategy was explicit: Tojo would be made to bear all responsibility. The roots of Japan’s wartime leadership stretched back decades. By 1945, the Japanese government was dominated by a military-industrial complex that had grown steadily since the Meiji Restoration of 1868.
At the apex stood Emperor Hirohito, whose theoretical authority was absolute, but whose actual role in decision-making remains debated to this day. Below him, a shifting coalition of generals, admirals, bureaucrats, and industrialists had steered Japan into 15 years of almost continuous warfare, beginning with the invasion of Manchuria in 1931. The men who had built this empire had done so through military conquest, industrial mobilization, and systematic brutality. Nanking in 1937 claimed an estimated 200,000 or more Chinese civilian lives.
Prisoners of war were routinely tortured, executed, or worked to death. In the jungles of Burma and Thailand, tens of thousands of Allied prisoners and Asian laborers died building the infamous death railway. And in a secret facility near Harbin in Japanese-occupied Manchuria, Unit 731 conducted biological warfare experiments on living human beings, injecting them with plague, cholera, and anthrax, performing vivisections without anesthesia. By any measure, the Japanese leadership bore responsibility for crimes on a massive scale.
On January 19th, 1946, MacArthur established the International Military Tribunal for the Far East, modeled on the Nuremberg trials then underway in Germany. Eleven nations provided judges and prosecutors. Australian judge Sir William Webb served as president, and American attorney Joseph Keenan was appointed chief prosecutor. The trials were held in the former building of the Japanese Ministry of War in Ichigaya, Tokyo, where Japan’s military leaders had once planned their campaigns of conquest.
Now they would answer for them. Twenty-eight defendants were eventually charged with Class A crimes, meaning crimes against peace: the planning, preparation, initiation, or waging of aggressive war. The list read like a roster of Japan’s wartime elite. Tojo, the wartime Prime Minister.
Koki Hirota, another former Prime Minister. Iwane Matsui, the general whose troops committed the Rape of Nanking. Kenji Doihara, the spymaster who had helped engineer the takeover of Manchuria. Seishiro Itagaki, the War Minister.
Heitaro Kimura, commander of Japanese forces in Burma. Akira Muto, chief of staff in the Philippines. They were charged with 55 separate counts, including waging wars of aggression, murder, and various war crimes and crimes against humanity. The Tokyo trial began on May 3rd, 1946, and would continue for more than two and a half years, far longer than its counterpart at Nuremberg.
The prosecution called 419 witnesses and introduced 4,336 exhibits of evidence. Day after day, the tribunal heard testimony about atrocities that shocked even those who thought they understood the brutality of the Pacific War. Survivors described the Bataan Death March, where thousands of American and Filipino prisoners died from exhaustion, starvation, and murder. Witnesses recounted the horrors of prisoner of war camps, where Allied soldiers were tortured, beheaded, and in some cases cannibalized.
Chinese survivors testified about the Rape of Nanking, where Japanese soldiers killed an estimated 200,000 civilians and raped perhaps 20,000 women in the first month of occupation alone. But the trial was also deeply flawed. The absence of Hirohito hung over the proceedings like an unspoken accusation. French judge Henri Bernard later wrote that the trial had been defective from the start due to the emperor’s absence, arguing that Japan’s declaration of war had a principal author who escaped all prosecution, and of whom the present defendants could only be considered accomplices.
Indian judge Radhabinod Pal went further, arguing that all defendants should be acquitted. Pal believed the tribunal was merely victor’s justice, noting that Western powers who sat in judgment had their own long histories of imperial aggression in Asia. He pointed out that no one was being tried for the atomic bombings of Hiroshima and Nagasaki, which he considered comparable to any crime the Japanese were accused of committing. During the trial, one particularly dramatic moment threatened to upset the careful arrangement that had protected Hirohito.
Tojo was being cross-examined about Japan’s decision to go to war when he stated that no Japanese subject could act against the emperor’s wishes. The implication was clear: if Tojo and the other defendants had waged aggressive war, they had done so with Hirohito’s approval. The courtroom fell silent. American officials scrambled.
Before Tojo’s next appearance on the stand, he was visited in Sugamo Prison and persuaded to modify his testimony. When he returned, Tojo dutifully explained that what he had meant was that the emperor had only reluctantly agreed to war after all peaceful options had been exhausted, that Hirohito had always been a man of peace constrained by his ministers and generals. The narrative held. Hirohito would remain untouched.
On November 4th, 1948, the verdicts were announced. All 25 surviving defendants were found guilty of at least one charge. Two defendants had died during the lengthy trial, and one had been declared mentally unfit after he slapped Tojo on the head during the opening session in a bizarre outburst. Seven men were sentenced to death: Tojo, Hirota, Matsui, Doihara, Itagaki, Kimura, and Muto.
Sixteen received life sentences. Two received lesser prison terms. On December 23rd, 1948, just two days before Christmas and a few days before what would have been Tojo’s 64th birthday, the seven condemned men were hanged at Sugamo Prison. They wore American Army work clothes with no insignia.
MacArthur, concerned about inflaming Japanese sensibilities, barred all photography. The bodies were cremated, and in a final act designed to prevent any future veneration, the ashes were scattered over the Pacific Ocean from an American military aircraft approximately 30 miles east of Yokohama. The extreme secrecy was deliberate. American officials were determined to prevent the executed men from becoming martyrs.
But the Tokyo trial was only the most visible part of a much larger reckoning. Across Asia and the Pacific, Allied nations conducted their own war crimes trials for Class B and C criminals, those accused of conventional war crimes and crimes against humanity. These trials, held in locations from Singapore to Manila to Hong Kong to Yokohama, ultimately convicted more than 5,000 Japanese military and civilian personnel. Approximately 900 were executed.
Australia alone conducted nearly 300 trials, convicting 644 Japanese servicemen and sentencing 148 to death. China held 13 tribunals, resulting in 504 convictions and 149 executions. The Soviets held the Khabarovsk trials in 1949, which tried members of Unit 731 for biological warfare crimes. What happened next complicates any simple narrative of justice served.
As the Cold War intensified, American priorities in Asia shifted dramatically. The Communist victory in China in 1949 and the outbreak of the Korean War in June 1950 transformed Japan from a defeated enemy into a vital ally against Soviet and Chinese expansion. The occupation authorities, who had begun by dismantling Japan’s military and purging its wartime leadership, now reversed course. The emphasis shifted from punishment to rehabilitation, from democratization to economic recovery, from excluding wartime leaders to quietly reintegrating them into Japanese society.
By 1956, all of the Class A war criminals who had received life sentences had been paroled. The 16 men imprisoned at Sugamo walked free less than a decade after their convictions. By the end of 1953, all surviving Class B and C prisoners had been returned to Japan, and by 1958, not a single convicted Japanese war criminal remained in prison anywhere in the world. Under Japanese law, those convicted at Tokyo and elsewhere were not considered criminals at all.
The government paid pensions to their families and, in some cases, to the convicted men themselves. Some of the men imprisoned as suspected war criminals never even faced trial, and their subsequent careers revealed just how dramatically the postwar winds had shifted. Nobusuke Kishi had been a key figure in Japan’s wartime regime, serving as Minister of Commerce and Industry in Tojo’s cabinet and co-signing the declaration of war against the United States on December 7th, 1941. During the 1930s, he had overseen the industrial development of Manchukuo, Japan’s puppet state in Manchuria, where he exploited Chinese slave labor and earned a reputation for ruthless efficiency that earned him the nickname Monster of the Showa era.
When the war ended, Kishi was arrested and held at Sugamo Prison as a suspected Class A war criminal. He spent more than three years awaiting a trial that never came. Forty-two suspects like Kishi were imprisoned in the expectation that they would be prosecuted at a second Tokyo tribunal, but the changing priorities of the Cold War meant that trial never materialized. In 1948, Kishi was released without ever being indicted.
He immediately returned to politics. By 1952, he had won election to the House of Representatives. In 1955, he played a central role in merging Japan’s conservative parties into the Liberal Democratic Party, which would dominate Japanese politics for decades. And in February 1957, Nobusuke Kishi, former war criminal suspect and co-signer of the declaration of war against America, became Prime Minister of Japan.
His grandson, Shinzo Abe, would also serve as prime minister twice. The question of Unit 731 and Japan’s biological warfare program represents perhaps the starkest example of justice sacrificed to strategic interest. Unit 731, commanded by Lieutenant General Shiro Ishii, had operated near Harbin, China, from 1936 to 1945. Its staff of 3,000 conducted some of the most horrific experiments in modern history.
Prisoners, mostly Chinese but including Russians, Koreans, and some Allied POWs, were deliberately infected with plague, cholera, anthrax, and other diseases. They were subjected to vivisection while fully conscious, their organs removed one by one so researchers could observe the effects of infection in real time. At least 3,000 people were killed at the Harbin facility alone, and estimates suggest Japanese biological warfare attacks across China killed tens of thousands more. When the war ended, Ishii and his staff fled to Japan, destroying much of the evidence behind them.
American intelligence officers soon caught up with Ishii, but instead of prosecuting him, they offered him a deal. In exchange for his research data, Ishii and the other Unit 731 leaders would receive complete immunity from war crimes prosecution. MacArthur personally approved the arrangement. The deal was concluded in 1948.
Ishii lived as a free man in Japan until his death from throat cancer in 1959. Many of his colleagues went on to distinguished careers in Japanese medicine, academia, and public health, including positions as president of the Japan Medical Association, head of the Japanese Olympic Committee, and governor of Tokyo. The Japanese government did not officially acknowledge the existence of Unit 731 and its activities until the 1980s. The legacy of the Tokyo trial and the broader reckoning with Japanese wartime leadership remains deeply contested.
For decades after the occupation, many Japanese accepted what historians call the victim narrative, a view of the war that emphasized Japanese suffering, particularly the atomic bombings and the firebombing of Japanese cities, while downplaying or ignoring Japan’s aggression and atrocities. The Tokyo trial was often portrayed as victor’s justice, its verdicts reflecting American power rather than genuine legal principles. This view found support in Pal’s dissenting opinion, which became widely read in Japan and is sometimes cited by nationalists to this day. The most visible symbol of this contested memory is Yasukuni Shrine in Tokyo.
The Shinto shrine was originally built in 1869 to honor Japan’s war dead, and now enshrines the souls of nearly 2. 5 million men who died in Japan’s wars. Among those 2. 5 million are more than 1,000 convicted war criminals, including 14 Class A criminals.
In October 1978, in a secret ceremony, the shrine’s head priest, who rejected the Tokyo War Crimes Tribunal’s verdicts, enshrined these 14 Class A war criminals, including Tojo and the six others who had been executed 30 years earlier. They were designated martyrs of Showa. When this became public in April 1979, Emperor Hirohito was reportedly so displeased that he never visited Yasukuni again. His son and grandson have maintained this boycott.
But visits to Yasukuni by Japanese prime ministers and cabinet members have become flashpoints for controversy, provoking outrage from China and South Korea. Emperor Hirohito himself remained on the throne until his death in January 1989, reigning for a total of 63 years and making him the longest-reigning monarch in Japanese history. Throughout the postwar decades, he carefully maintained his role as a symbol of national unity while avoiding any discussion of the war or his role in it. When he traveled to Europe in the 1970s, he was met by protesters in Britain and the Netherlands, veterans who had suffered under Japanese occupation and could not forgive.
In the Netherlands, eggs and vacuum flasks were thrown. In Britain, protesters stood in silence and turned their backs. But in Japan, Hirohito remained revered by most citizens. When he died on January 7th, 1989 at the age of 87, Japan entered a period of official mourning.
Television broadcasts were suspended, events were canceled, and Japanese of all ages lined up to pay their respects. The man who had presided over Japan’s greatest military expansion and its catastrophic defeat, who had escaped trial through American protection and strategic calculation, was mourned as a beloved national figure. His era name, Showa, meaning enlightened peace or radiant Japan, remains officially how that period is designated in Japanese history, despite the irony of applying such a name to decades of war and disaster. Today, nearly 80 years after the end of World War II, the questions raised by the Tokyo trial and its aftermath remain unresolved.
Japan has never issued the kind of comprehensive apology and acknowledgement of war crimes that Germany undertook through its process of coming to terms with the past. What remains is the historical record, the crimes committed, the trial that convicted them, the executions that ended those lives, and the long decades during which a nation lived with consequences it did not choose but could not escape.
