On September 12, 1944, on Angel Island in San Francisco Bay, a Japanese prisoner of war stood alone in barracks room 109. He had just crossed the Pacific on an American ship, been processed through inspection, given a serial number, fingerprinted, photographed, and examined by a doctor. Now he had a few minutes alone with a wall, and he wrote on it. History does not record his name, his unit, or where he was captured.
It records his words. Translated into English and preserved by the Angel Island Immigration Station Foundation, they read: “We arrived here on September 12. We did not find a place to die. We were captured and held here.
” That was the entire message, the first thing this man chose to leave on American soil. Any ship entering that bay from the open Pacific had to pass under the Golden Gate Bridge, completed in 1937. Beyond it lay shipyards, cranes, docks, and a city climbing its hills. The man had just been transported to the largest industrial economy on earth.
Yet his first written sentence ignored all of it. The popular version of this story runs in another direction: that Japanese prisoners were stunned by America, saw the food, the cars, the lit streets, and something inside them broke. They talked because the country amazed them. It is a satisfying story, and it did not come from nowhere.
But the wall in room 109 is a document, and the document says something different. By the end of the war, the United States held more than 425,000 prisoners of war on its soil. Roughly 372,000 were German, about 53,000 Italian, and around 5,000 Japanese. Five thousand out of more than 400,000.
That ratio shaped everything that followed. The first Japanese prisoner taken by American forces in World War II came ashore on the morning of December 7, 1941, during the attack on Pearl Harbor. His name was Kazuo Sakamaki, a twenty-three-year-old sub-lieutenant in the Imperial Japanese Navy. He commanded a midget submarine with the designation HA-19, a two-man vessel not much larger than a bus, carried to its target on the deck of a larger submarine.
His compass failed. The boat struck a coral reef off Oahu. He swam to Waimanalo Beach unconscious, where a soldier found him. Five midget submarines took part in that attack, carrying crews of ten men.
Nine died. Sakamaki was the tenth. Brought to Sand Island, a detention site in Honolulu Harbor, he reportedly burned himself with cigarettes and asked permission to kill himself. The request was denied.
That request was the first thing records show a Japanese prisoner saying to his American captors. On March 1, 1942, Sakamaki arrived at Angel Island, and on March 9 he reached Camp McCoy in Wisconsin. Over the next four years he moved between camps in Wisconsin, Tennessee, Louisiana, and Texas, returning to Japan in 1946. Angel Island was the main gateway.
The army converted the North Garrison into a processing station on December 8, 1941, the day after the attack. Each arriving prisoner passed through ten stations: inspection, serial number, fingerprints, photograph, medical exam, and bed assignment. The entire process was timed at one hour and eighteen minutes. Prisoners received additional procedures.
Their uniforms were deloused, their blankets sterilized, blood samples drawn, vaccinations given. Doctors treated malaria, skin diseases, intestinal worms, and wounds that had gone untreated in the islands. In July 1942 the first group of Japanese prisoners was held there: five officers and thirty-five soldiers. On May 18, 1944, the island held 528 prisoners.
On September 13, 1944, the day after the unknown man wrote on the wall, 450 more arrived. By February 24, 1945, only four remained. By July 2, 1945, the number had climbed back to 254, including fifteen officers. From Angel Island, most prisoners moved to a place that never appeared on public maps.
It was a hotel resort at Byron Hot Springs, east of San Francisco, taken over by the army and renamed Camp Tracy. It opened in 1943 and closed on September 1, 1945. In 1944 alone, about 921 Japanese prisoners were interrogated there, along with 645 Germans. The population never exceeded 51 men at any one time.
Fifty-one men in a hotel built for paying guests. Camp McCoy in Wisconsin became the largest Japanese prisoner-of-war site in the continental United States, with army records placing the number at 2,700 Japanese prisoners and local studies suggesting 3,500. Camp Clarinda in Iowa received 1,055 Japanese prisoners from early 1945, mostly naval personnel. Others passed through camps in Texas.
The easy explanation says prisoners talked because America amazed them, that abundance broke their faith, that they saw the country’s size and realized the war was lost. If that were true, the talking would have begun after seeing America. The record says it began earlier. In early 1943, a naval investigator named Otis Carey was assigned to the prisoner camp at Pearl Harbor.
His first prisoner gave him information that his obituary described as vital to the American campaign in the Aleutian Islands. That man had never seen an American city, only a fence in Hawaii and an investigator across a table. The real difference between German and Japanese prisoners lay in their instructions. The German soldier belonged to a country that had ratified the 1929 Geneva Convention on prisoners of war, a treaty spelling out what a prisoner must give, what he can refuse, what work he can be forced to do, and what food and letters he is owed.
The Japanese soldier belonged to a country that signed the treaty but never ratified it. The German soldier learned that if captured, he must give his name, rank, and serial number, nothing more. The Japanese soldier carried a different text: the Senjinkun, battlefield instructions issued on January 8, 1941, in the name of War Minister Hideki Tojo. Its most famous line in standard English translation reads: “Do not live to experience the shame of being a prisoner.
In death, you will avoid leaving a stain on your honor. ” The Japanese army did not train its men on how to behave after capture, because training for capture meant acknowledging that capture was possible. The American side of the table was built with care. Camp Tracy’s rooms were originally hotel rooms.
Prisoners ate Japanese food prepared by cooks brought in for that purpose. Many interrogators were Nisei, Americans born to Japanese immigrant parents, who spoke the language natively and understood prisoners’ fears. Every room was wired for sound, with microphones hidden inside lighting fixtures and wires running through hollow walls to a recording room on the ground floor. Listening devices were hidden in trees near the outdoor recreation area.
One former officer summarized the logic: they felt they could get information through a system of rewards more than punishment. The results were tangible. Naval prisoners described Japanese radar, naval armament, and ship capabilities. A prisoner captured on Iwo Jima described ammunition factories and unit code names.
In 1945, Japanese medical officers held at the camp provided information on biological weapons research. Prisoners expected beatings and death. Instead they received cigarettes, Japanese food, and a man who knew their hometown. The shock of kindness is what opened them.
One testimony from the Hawaiian camps states it directly: prisoners were not terrorized by harsh treatment, but kindness, chocolate, and cigarettes surprised them so much they disclosed valuable military information. But kindness only works on a man who has no instructions. Give chocolate to a German sergeant and he will thank you, then give you his name, rank, and serial number. Give it to a man whose only instruction was to die, and you are speaking to a void his army left empty.
Yet Japan knew how prisoner-of-war systems worked. During World War I, Japan fought on the Allied side and captured several thousand German soldiers at the German base in Qingdao, China. Some were held at a camp called Bando near Tokushima, which became famous for how its prisoners lived. They printed newspapers, ran workshops, baked bread, and formed musical groups.
In June 1918, the prisoners at Bando gave what is remembered as the Japanese premiere of Beethoven’s Ninth Symphony, an event Japanese cities still celebrate. Japan in 1918 understood exactly how to feed prisoners, house them, allow them to write home, and return them to their countries. Twenty-three years later, the same state issued a booklet telling its soldiers they must never be captured. That was not ignorance.
That was a choice. The cost of that choice can be counted in ratios. The number of prisoners to dead changed dramatically: one prisoner for every 100 Japanese dead in November 1944, one for every 60 in January 1945, one for every 30 in April, and one for every seven in July. In early 1945, 46 percent of Japanese prisoners interrogated in one American series said the propaganda leaflets had influenced them.
But some prisoners turned their captivity into a battlefield. On February 25, 1943, at Featherston camp in New Zealand, about 240 Japanese prisoners staged a sit-down protest against work orders. Officers were forcibly removed. A New Zealand officer fired and wounded a Japanese sub-lieutenant named Adachi.
Then guards opened fire with rifles, machine guns, and pistols for fifteen to thirty seconds. Forty-eight Japanese prisoners were killed, and seventy-four wounded. One New Zealand guard was killed by a ricochet. On August 5, 1944, at Cowra in New South Wales, more than a thousand Japanese prisoners were told they would be separated from their officers.
Around 2 a. m. they climbed the fence, throwing blankets over the barbed wire, carrying knives, baseball bats, studded clubs, and garrotes. Two Australian soldiers, Benjamin Hardy and Ralph Jones, were credited with disabling a Vickers machine gun before it could be turned on the camp’s defenders.
Both were killed and posthumously awarded the George Cross. Four Australian soldiers died that night. Two hundred thirty-one Japanese prisoners died, many by their own hands or those of their countrymen. Every escaped prisoner was recaptured within ten days.
At the Baïta camp in New Caledonia in January 1944, a planned uprising failed and twenty-four prisoners committed suicide. An inquiry into the Featherston shootings concluded that cultural misunderstanding played a large role. The Japanese prisoners did not know that the 1929 Geneva Convention allowed captors to demand work from ordinary prisoners, so the protest had been based on a false premise. No one had explained the rulebook to the men inside because their own army had refused to provide it.
At Cowra, the immediate cause was an administrative order separating ordinary soldiers from their officers, dismantling the last structure that gave each man his identity inside a camp where he no longer had any recognized status at home. And the cost followed the survivors home. When Sakamaki returned to Japan in 1946, he received letters demanding he commit ritual suicide and apologize for the shame of capture. His name had already been erased from the official record.
After the war he became a historian and professor at the University of Hawaii, writing a memoir published in 2009. He recalled the morning he arrived at Angel Island: the barracks were full of bright morning sun, and except for the wire fence and guard towers, the American prisoner-of-war camp did not resemble the prison he had feared. In 1991, Sakamaki came to Fredericksburg, Texas, for a seminar marking the fiftieth anniversary of the Pearl Harbor attack. He saw his submarine for the first time in half a century and wept.
He asked to visit the Alamo and the site of his old camp at Kennedy. Camp Kennedy had been demolished. He recognized one thing: the water pump that had stood in the middle of the compound, now in a mayor’s front yard. Asked why he had never tried to escape, he said the guards collected everyone’s shoes at night and served ice cream, and there was no point leaving barefoot through the burrs in the grass.
A local doctor who accompanied him remembered that Sakamaki always felt he had cheated his country by not completing the sacrifice. Yet in his 1949 memoir, published in English as I Attacked Pearl Harbor, he wrote about humane treatment. He wrote that in the spring of 1942, he began to feel like a human being again. He described a program prisoners called “University of Captivity,” with lectures in English, geography, commerce, agriculture, music, Japanese poetry, and Buddhist texts.
He became a leader among the Japanese prisoners, encouraging new arrivals to learn English and persuading recently captured men not to commit suicide. So what did Japanese prisoners actually say when they saw America for the first time? First, they said they had failed to die. That was the request on Sand Island and the sentence written on the wall in room 109.
Second, they asked that their families not be notified. That was their greatest fear, in the words of the interrogators who heard it repeatedly. Third, once given a table, a cigarette, Japanese food, and a person who knew their hometown, they said almost everything: unit names, radar, ship armament, ammunition factories, code names, even the right word to put on propaganda leaflets. And only after all that, after months or years, some of them said something about America itself.
What they said was not that it was rich. What they said was that it was not the prison they had feared. The country did not open these men. A booklet printed in Tokyo had already stripped them of instructions, and an American system built of hotel rooms, linguists, and microphones filled that silence.
A system that refuses to plan for its failure does not prevent failure. It hands the script for that failure to the enemy. The wall in room 109, read with the full record behind it, is the last line of a script written in January 1941, spoken by a man standing outside it for the first time. He records the date.
He records the place. He records that he is alive. Those are the first three facts any prisoner gives under any rulebook his army refused to provide.
