What the Navy Did With Six Million Japanese Still Stranded Overseas When the War Ended
Two large passenger ships came through the war still afloat. On the tenth of September 1945, one of them lay at Maizuru on the Sea of Japan with her wards empty and the red crosses still painted along her sides. She was the Hikawa Maru, built at Yokohama in 1929 for the Seattle run, taken by the navy a fortnight before Pearl Harbor and fitted out to carry the sick.
She had struck mines three times in four years of war and had come home on each occasion, saved by hull plating thicker than the yards were building into anything else. That morning she took on stores and stood out to sea under orders written eleven days earlier. Six and a half million Japanese were outside Japan, and somebody had to go and fetch them.
About half of that number wore uniforms, standing down on atolls, in the hills of Luzon, along the Yangtze, in Manchuria, in Java. The rest were farmers and clerks and schoolteachers and their children, scattered across an empire that had taken fifty years to assemble and eight days to lose. None of them could walk home.
Every one of them had to cross salt water in something, and the something did not exist. There was paperwork before there were ships: reception ports were named that autumn, quarantine duties allotted, and one of the names on the list was Uraga, a small town on a peninsula at the mouth of Tokyo Bay. Seventeen days out, the Hikawa Maru anchored off Mille in the Marshall Islands.
The garrison there had been bypassed in 1944 and left to itself, out of reach of its own supply and never worth the cost of an assault. Its men had spent a year and a half growing what they could eat in coral sand and listening to aircraft that had stopped bothering to attack them. She loaded and sailed the same day.
On the seventh of October she put her passengers ashore at Uraga, where a Marine regiment stood on the wharf and watched them come off, and by the end of the month she was at Wake, and after Wake at Kusaie, and after Kusaie at Wewak and Rabaul and Morotai and Halmahera and Manado, atoll to island to anchorage, down a list that looked like a table of contents for the whole Pacific campaign.
The war had been over for six weeks and the islands were still full. In the Southwest Pacific alone the surrendered garrisons ran to hundreds of thousands of men who had been written off as beaten two years earlier and were now, all at once, an administrative problem with a shipping requirement attached to it.
Not everyone liked it. American troops waiting on their own passage back to the United States complained that hulls were going to the people they had been shooting at in August. Officials answered that Asia would not settle while the garrisons sat in it, and that leaving them where they were would keep more Americans overseas rather than fewer.

The ship’s file number under the new arrangement was H-022, and she carried it stenciled on her for the next two years. The arrangement itself had a title so flat it barely registers as one: the Shipping Control Authority for the Japanese Merchant Marine, stood up under American naval command that October.
Its first task was to establish what Japan had left, and that turned out to be harder than it sounds, because the Navy Ministry had burned most of its files in the last week of the war. The tally had to be built by going port to port and asking local officials what was tied up where, and the officers doing the asking noted with some surprise that the answers held up.
The ministry had destroyed its papers to keep them from the Americans, and then had to tell the Americans what had been in them. The count found afloat and undamaged one fleet carrier, one light carrier, a pair of light cruisers, about thirty destroyers, and more submarines than anything else. It came out on the fourth of December as a printed list of every surviving hull worth the fuel, and that list is where the whole operation starts.
Merchant shipping was worse. What survived amounted to splinters and small craft, thousands of wooden coasters and harbor boats under a hundred tons, almost none of which could take a load of people across an ocean and land them alive at the other end. The Navy’s answer was to give the fleet back.
At a conference in Tokyo on the seventh of December, the recommendation went up that surplus American shipping be handed to the defeated enemy outright, crewed by the enemy, and worked under American control until the job was done. Nobody had tried anything of the kind before, and there was no legal machinery sitting ready for it. What arrived was a hundred and six Liberty ships and a hundred landing ships, the flat-bottomed kind with the doors in the front end, every one of them already marked for scrapping or for laying up in some backwater. Eighty-five of the landing ships stayed on the run home
and the rest went to work supplying Korea. Japanese yards cut them about for passengers, building bunks into cargo spaces and washing arrangements onto the decks. Instruments and hatch markings were redone in kanji so the new crews could make sense of what they were looking at. Converted ships went into service at about twenty-five a week.
Six of the Liberties were rebuilt as floating hospitals with more than a thousand beds apiece, and American officers ran training for the crews who would take all of it over, teaching a merchant service that had been sunk out from under itself how to work ships built to another country’s drawings.
By the end of March the authority had enough capacity of its own that the Seventh Fleet was released from the work altogether and went back to being a fleet. Crews were the other half of the problem, and the answer there was to stop the clock. The Navy Ministry held thousands of its own sailors back from demobilization so the ships would have somebody aboard who understood them, which meant that the men who carried the enemy home were the same men who had been fighting a fortnight before.
What remained of the Imperial Japanese Navy went back to sea with the guns taken off. The carriers Hosho and Katsuragi, two of the handful that survived the bombing, ran as ferries. Destroyers ran as ferries. So did submarines that had been disarmed and could no longer dive, sent out on short daylight hauls where nobody would have to sleep aboard.
Something else was moving in the opposite direction. More than a million people inside Japan, Koreans and Chinese and Formosans brought there for wartime labor, were waiting to leave, and they went out on the same hulls that were coming in loaded. The American voyage home got a name, Magic Carpet, and a place in every account of the period. This one ran for two years under an acronym and has never had either.
Prying out the operations that were never given a name is most of what this channel does, so subscribe if that seems worth having, and press like on the way past. The rising sun ensign had been abolished, which left the question of what these ships were supposed to fly. The answer came out of the international signal book.
Hulls owned in Japan and crewed by her sailors flew a blue and red pennant taken from the flag for Echo. Hulls owned by the United States and crewed the same way flew red and green triangles taken from Oscar, so that any Allied ship or aircraft could tell at a glance which was which. Tokyo fed and supplied the crews.
Fuel had to be bought through American authorities, which kept a hand on the throttle of the entire operation without anybody having to give an order. Cargo hulls stayed out of the lift on purpose, because a country with no food coming in could not spare the few ships that were feeding it. When a pair of these ships put into Hawaii for repairs, the men aboard were not permitted ashore.
Then there was the water itself. General Order Number One, issued the day the surrender was signed, dissolved Japan’s armed forces and in the same breath instructed her government to keep its minesweeping organization in being, because the approaches to the home islands were a killing ground and everybody involved knew it.
B-29s and American submarines had laid better than ten thousand mines in those waters. Japan had laid many times that number defending herself and had cleared almost none of it. From November the sweepers came under an American task group and worked to a plan for the first time since the surrender: ten thousand former navy men and a few hundred small vessels under a mine warfare specialist named Tamura, exempted from the purge of officers because there was nobody else who could do the job.
That work ran for years and it killed men the whole way through. Ships kept going down a few hundred yards off shore, in sight of the people waiting for them. One ship struck a mine near the China coast with four thousand three hundred aboard, and twenty were lost, which given the circumstances counted as a good day. The routes multiplied through the winter.
Ships came off the Pacific islands, out of Shanghai and Canton, down from Keelung, and by spring the northern routes were opening as well. Then, in April, a ship out of Canton reached Uraga with cholera aboard, and she was inside the harbor before anyone knew it. Twenty ships were held at anchor offshore with something like seventy thousand people aboard them, near enough to the shore to make out the hills behind it. About four hundred died out there without setting foot in Japan.

The Public Health and Welfare Section under Crawford Sams, an Army doctor who had spent the previous autumn arguing that Japan’s prewar quarantine stations had lapsed during the war and needed rebuilding before the sailing season, got his stations. Ships out of infected Chinese ports went to Uraga and Sasebo, and later Hakata, the three places where facilities could be made to work.
Uraga earned its place because it sat on a small peninsula and could be sealed off from everything around it, which was the right answer for disease and the wrong one for weather: the anchorage was open, and the ships waiting in it took the sea broadside for weeks. Laboratory equipment able to handle thousands of cultures a day was assembled at Uraga inside a few weeks, and detention sheds went up beside it.
On the wharves, every arriving passenger and every piece of baggage got a dusting of DDT powder, which is why the photographs from those months show people standing in a white haze with their arms held out from their sides. Formosa was its own kind of trouble. Hundreds of thousands of Japanese civilians there had been born on the island and had never seen Japan, and most of them wanted to stay.
The Chinese authorities intended to keep the useful ones and were charging the rest for their passage and their inoculations, both of which the United States was providing at no cost, which produced a run of American objections that went nowhere. The northern half of the map was worse and slower.
Soviet troops had gone into Manchuria in the last week of the war and showed no interest in moving anybody out of it. Not until they began pulling back in May 1946 could the lift up there start at all, and when it did it ran on American shipping through a single port, Huludao on the Manchurian coast. People reached that port on foot.
Some had walked from near the Soviet frontier, better than a thousand miles, and had been living rough through a Manchurian winter before there was a ship in existence to take them off. On the Japanese end the traffic came ashore at Hakata, Senzaki, Sasebo, Uraga, Maizuru, Kagoshima and a scatter of smaller places, each with its sheds, its dusting station and its own bridge built out over the water for people to walk down.
Who was actually running the shipping authority is not settled in the American files. The Pacific Fleet’s own report of February 1946 names Rear Admiral Donald Beary as its administrator. The Navy’s biographical file on Charles Momsen says that he was ordered to that same post after the surrender and served in Japan from November 1945 to October 1946.
A later account splits the difference and puts Beary in command with Momsen as his chief of staff. The three do not reconcile, and nobody at the time seems to have thought it worth sorting out. It was Momsen who put the number on paper. The first reckoning had the job running until July 1947, which everybody treated as reasonable for an operation that had begun with two serviceable liners and a fleet of coastal junk, and in March 1946 he wrote that it would be finished that May.
He was near enough. Within a year of that memorandum more than six million people had been landed in Japan, and the ships had also brought back the exhumed remains of thousands of Japanese war dead from islands nobody was ever going to visit again, which the government in Tokyo had asked for and had not expected to get.
The Hikawa Maru finished her last government voyage in January 1947. She went back to hauling cargo through the lean years, then to passengers, ran the Seattle line again in the fifties, and came out of service in 1960 when people stopped crossing the Pacific by ship.
She is tied up at Yamashita Park in Yokohama today with schoolchildren walking her decks, the last big Japanese liner of her generation still in one piece, and there is nothing aboard her that tells anybody what she was doing in the autumn of 1945. The forecast came with one exception written into it, and the exception outlived everything else in the file.
The people in Soviet hands were not coming, whatever schedule the Navy drew up for them. Manchuria, Sakhalin, the Kuriles, then the camps, and men were still stepping onto the bridge at Maizuru in 1958. The citation for that year’s work credits its author with something no other American officer of the war could claim, “the safe and expeditious return of millions of displaced persons to their homes.
” The man who spent the 1930s working out how to pull thirty-three sailors out of a sunken submarine got six million people off a continent in eight months, and the only part of his arithmetic that ever failed was the part he had flagged himself as the part he could not reach.
