How Okinawans Emigrated to Taiwan

From Liminality of the Japanese Empire: Border Crossings from Okinawa to Colonial Taiwan, by Hiroko Matsuda (U. Hawaii Press, 2018), Kindle loc. ~1800:

Okinawans usually did not go to colonial Taiwan through an intermediary. Instead, they relied on their network of family or friends. It was not unusual for Okinawan youths without work experience to arrive in Taiwan not knowing what they were going to do. Moreover, the immigrants frequently changed workplaces. It would indeed be difficult to track each immigrant’s career in Taiwan because it was common to see an unskilled immigrant start out as a shop boy or factory laborer and eventually secure work as a government employee or a policeman after living in Taiwan for several years. Employers might deplore the tendency to change jobs frequently, but this shows the Okinawan immigrants’ agency and willingness to advance socially in the colony.

…

Enrolling in evening school was a common means of achieving social mobility for young Okinawan male migrants who could not afford a secondary education at home.

Nevertheless, for Okinawan migrants in Taiwan, becoming an apprentice was the most common method of acquiring a professional skill and advancing their careers. Japan’s decchi [丁稚] system, which developed in the shogunal period, was similar to the Western apprenticeship and played an important role in the Japanese commercial world until the nineteenth century. It originally assumed a feudalistic relationship between a master and an apprentice, rather than a contractual relationship. The apprentice owed his master long-term loyalty because his master treated him like a family member. This custom persisted well into the early twentieth century. Although it became less feudalistic in the twentieth century, and an apprentice was less likely to serve a master for a long time, the practice still maintained an element of folkloric education.

Through apprenticeships, Okinawan youth migrants who could not afford higher education at home acquired the knowledge and skills they needed to raise their social positions.

Okinawan Emigration Destinations

From Liminality of the Japanese Empire: Border Crossings from Okinawa to Colonial Taiwan, by Hiroko Matsuda (U. Hawaii Press, 2018), Kindle loc. ~840:

Before migration to the US mainland became popular in Okinawa, anti-Japanese sentiment spread across the West Coast, where the Japanese population had increased rapidly at the turn of the twentieth century. After the enactment of the Gentlemen’s Agreement in 1908, Okinawans were unable to enter the United States as migrant laborers. Thus, very few Okinawans followed the thousands of Japanese who had migrated to the US mainland. The few who did so during this period were youths pursuing higher education. Some went to the US mainland via Hawai‘i, Canada, and Mexico; a few traveled directly from Okinawa. As the Gentlemen’s Agreement allowed only families of migrants to enter for the purpose of reuniting with husbands and fathers, some female Okinawans arranged to immigrate and join their grooms in the United States as picture brides.

Elderly Okinawans have a saying that best sums up these migration trends: “The richest people were able to immigrate to South America; people with some money migrated to the Philippines; and the poorest worked on mainland Japan.” Indeed, when it proved too difficult to enter the United States as migrant workers, the Japanese turned to South America—especially Brazil—and the Philippines as alternative destinations. Later, the South Sea Islands [Micronesia] became popular as the South Seas Development Company (Nan’yō Kōhatsu) targeted and recruited Okinawan laborers for its sugar industry. While Brazil, the Philippines, and the South Sea Islands were under different governments and Okinawan immigrants there worked in different industries, there are some commonalities among them. First, the initial immigrants in these countries worked in manufacturing and commercial crop industries such as coffee (Brazil), abaca [aka “manila hemp”]  (the Philippines), and sugarcane (the South Sea Islands). Second, Okinawan immigrants accounted for the majority of Japanese immigrant communities in these countries despite their treatment as “second-class Japanese” and “the other Japanese.”

Japan sent the first indentured migrant farmworkers to Brazil in 1908. Okinawans accounted for more than 40 percent, 325 of the 781 immigrants, of that inaugural group of economic immigrants to Brazil. In fact, many of the first Okinawan immigrants left the plantations to which they were allocated shortly after their arrival. This gave a negative impression to both the Japanese and Brazilian governments. In 1913, the Japanese government refused to accept Okinawans wishing to travel to Brazil as indentured laborers, citing their propensity to leave the plantations and their cultural difference from Japanese workers from the other prefectures, but when migration agencies were unable to recruit enough laborers from the other prefectures, Okinawans were once again permitted to go to Brazil as indentured migrant workers. However, as was the case in the United States, Okinawan migration to Brazil was prohibited in 1919, and only immigrants who were currently in Brazil were allowed to send for their families.

…

In addition to Brazil, Okinawa sent a significant number of immigrants to other Latin American countries. For instance, Peru quickly became one of the most popular destinations for Okinawan migrant workers after the first group of Okinawan immigrants arrived there in 1899. Between 1899 and 1941, Okinawa sent 11,461 immigrants to Peru, accounting for nearly 30 percent of the total number of Japanese immigrants. Although the immigrants were initially employed on plantation farms, many later moved to urban areas, where they became grocery store or restaurant owners.

…

Similarly, most Japanese immigrants to Argentina were Okinawans. This is despite the fact that Japanese immigrants had been arriving in Argentina since 1910. There were 1,831 Okinawans in Argentina in 1940, accounting for approximately 45 percent of the Japanese population in the country. Not all Okinawans in Argentina had migrated directly from Okinawa; in actuality, many ended up in Argentina after traveling to Brazil and Peru. In Argentina, many Okinawans initially found work as factory laborers or porters. A sizeable number eventually set up small businesses such as coffee shops and laundries.

Defining Japan’s Southern Periphery

From Liminality of the Japanese Empire: Border Crossings from Okinawa to Colonial Taiwan, by Hiroko Matsuda (U. Hawaii Press, 2018), Kindle loc. ~415:

Before proceeding, I should clarify the usages of the key terms in this volume, including “Ryukyu,” “Okinawa,” “Mainland Japan,” “Inner Territory,” and “Outer Territories.” The geographical name “Ryukyu” appears in Chinese historical documents such as the Book of Sui, which was written in the seventh century. In the fifteenth century, “Ryukyu” became the official name of the kingdom unifying the archipelagos of Amami, Okinawa, Miyako, and Yaeyama, known today as the Ryukyu Islands or Southwest Islands. Under the Ryukyu Kingdom’s rule, the name “Okinawa” indicated the main island of Okinawa and surrounding small islands. In 1872, Japan’s Meiji government changed the kingdom’s status to that of a domain (han) by fiat; the government then declared the abolishment of the kingdom and the establishment of Okinawa Prefecture in 1879. However, as Wendy Matsumura explains, the word “Okinawa” is not a neutral geographical title referring to a Japanese prefecture but a term that implies a cultural community distinct from the Japanese nation-state. This volume loosely defines “Okinawans” as people whose families and relatives originated in Okinawa Prefecture or the Ryukyu Islands. The term “Okinawans” therefore encompasses people of diverse backgrounds, including those born in Okinawa Prefecture and those born and raised in Taiwan whose parents were born in Okinawa Prefecture. In fact, people from the Yaeyama and Miyako Islands often distinguish themselves from “Okinawans” even though they are part of Okinawa Prefecture, identifying themselves as people of Yaeyama and Miyako rather than as Okinawans. Nonetheless, in this volume, the term “Okinawans” includes people with Yaeyama and Miyako backgrounds unless otherwise indicated.

Likewise, in this volume, the term “Mainland Japan” loosely indicates the islands of Honshu, Shikoku, and Kyushu. As the following chapters reveal, the word “Japanese” occasionally includes and excludes “Okinawan.” In other words, the social and cultural categories of “Japanese/the others” and “Okinawan/the others” have been persistent, although the categories are malleable and changeable. Mainland Japan is geographically ambiguous, but the notion of such a place suggests that Okinawans are “the others,” as Mainland Japan was considered dominant over the local islanders. In Okinawa Prefecture, Mainland Japan has customarily been called the “Inner Territory” (Naichi). However, to avoid confusion, this volume defines the Inner Territory as the territory under the rule of the Meiji Constitution (Constitution of the Great Japanese Empire). The notion complements the idea of the “Outer Territories” (Gaichi), which refers to the territories excluded from the Meiji Constitution.

Japanese Shipping Losses, 1943-44

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 249, 250-251:

November 1943, one month after Dot’s arrival at Arlington Hall, marked the war’s most devastating month for Japanese tonnage sunk. U.S. subs sank forty-three ships and damaged twenty-two. American sub captains received intelligence of seventy-six movements of enemy ships. In December, American subs sank or damaged about 350,000 tons, including thirty-two ships sunk and sixteen damaged.

Behind the success of the U.S. Navy were the code breakers. “The success of undersea warfare is to a certain extent due to the success with which Japanese code messages were translated,” noted a naval report. An American naval commander pointed out in a postwar memo that sometimes a convoy might slip through, but only because U.S. submarines were kept so busy by information from decoded messages that they could not handle all the convoys they were alerted to. Over at the Naval Annex, the assembly line of WAVES identified the movements of marus [merchant marine ships] supplying the Japanese Navy. Findings from both operations found their way to the submarine captains, who could hardly keep up with the bounty of intelligence.

…

The devastation of Japan’s shipping had an enormous impact. Soldiers were deprived of food and medicine. Aircraft did not get spare parts and could not launch missions. Troops did not reach the places they were sent as reinforcements. On March 12, 1944, a broken 2468 message gave the route and schedule of the Twenty-First Wewak Transport convoy, sunk while leaving Wewak to return to Palau. When the Japanese Eighteenth Area Army made a “complete tabulation of shipping from Rabaul and Truk during January,” in an attempt to convince Japanese Army headquarters that it was feasible to send them much-needed supplies, these messages laid out the shipping routes and sealed their doom. Only 50 percent of ships reached the destination; only 30 percent got home.

At the end of the war, a U.S. naval report found that “more than two-thirds of the entire Japanese merchant marine and numerous warships, including some of every category, were sunk. These sinkings resulted, by mid-1944, in isolation of Japan from her overseas sources of raw materials and petroleum, with far reaching effects on the capability of her war industry to produce and her armed forces to operate. Her outlying bases were weakened by lack of reinforcements and supplies and fell victim to our air, surface and amphibious assaults; heavy bombers moved into the captured bases.” This report’s author, C. A. Lockwood, commander of the submarine force of the U.S. Pacific Fleet, noted that his men got a “continuous flow of information on Japanese naval and merchant shipping, convoy routing and composition, damage sustained from submarine attacks, anti-submarine measures employed or to be employed, effectiveness of our torpedoes, and a wealth of other pertinent intelligence.” Whenever code breaking was unavailable, he added, “its absence was keenly felt. The curve of enemy contacts and of consequent sinkings almost exactly paralleled the curve of volume of Communication Intelligence available.”

He added: “There were many periods when every single U.S. sub in the Pacific was busy” responding.

In fact, he added, code-breaking intelligence made it seem to the Japanese that there were more American submarines in the Pacific than there really were. “In early 1945 it was learned from a Japanese prisoner of war that it was [a] common saying in Singapore that you could walk from that port to Japan on American periscopes. This feeling among the Japanese was undoubtedly created, not by the great number of submarines on patrol, but rather by the fact, thanks to communications intelligence, that submarines were always at the same place as Japanese ships.”

Japanese Transport Code Language

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 244-246:

The language of the 2468 [transport code] messages was telegraphic in style. Short, straightforward, and no-nonsense, the messages consisted of sailing schedules, harbormaster reports, reports on the water levels of ports and transportation of cargo. Sailing schedules were the simplest. These included the transport number, the date, the time the maru [ship name] would be arriving or leaving, and its destination. Others concerned the movement of troops or equipment. A few dealt with transportation of the wounded or ashes of the dead. The marus out there in the Pacific Ocean carried everything: food, oil, supplies, human remains.

When a new message arrived, Dot looked for stereotypes, which were words that occurred frequently in the same place. “Maru” was a common one, but there were others as well, depending on the origin and the goods being transported. For example, one station transmitting from Singapore—the #3 Sen San Yusoo—sent a regular report on the shipping of oil to Hiroshima, Manila, and Tokyo. Stereotyped words might include ship names and numbers; the number of kiloliters of light oil, crude oil, heavy oil, aviation gasoline, or other gasoline aboard; how many trips each ship would take, and when. Another Singapore station transmitted to Hiroshima, Tokyo, and Moji a report of ships leaving for Palembang. Stereotypes might include the ship number or name, the date and hour of departure, the speed, the course, and the date and hour of scheduled arrival at the mouth of the Musi River.

Another transmitted a daily weather report with data including wind velocity and direction, temperature, and condition of the surface of the Andaman Sea, the South China Sea, the Yellow Sea, and other faraway bodies of water. Dot handled a lot of weather reports. Sitting at her table in Arlington, Virginia, Dot was amused at how many bits and pieces of information she knew about what the weather was like eight thousand miles away.

Another station transmitted a report on small boats available for supply services. Mentioned might be steel barges, wooden barges, special boats, small boats, twenty-metric-ton boats, plywood barges, and cargo submarines.

A station at Surabaya originated a report on the departure of ships escorted by a single Navy plane, including the names and types of ships (motor, sail, fishing), number of barges being towed, date of departure and destination, speed, scheduled date of arrival, route, and daily position of ship on consecutive days at given hours. A report from Shanghai about a supply ship might include a message spelling out that the probable route was “from Shanghai along the coast to the Yangtze River up the Yangtze River to WUU (Buko) down the river to Nanking and finally across the East China Sea to Moji.”

Here is how Dot did her work: Let’s say she knew that the code group for “arriving” was 6286 and she knew where this word was likely to appear. She would find that place in the message and look at the GAT [“group as transmitted”] before her. Books at Arlington Hall listed common code words as well as possible enciphered versions. She would look for a match, or she could do the math in her head and strip out the additive herself. Sometimes—when they were desperate—the code breakers would take the code groups and encipher them with every possible additive. A smattering of 2468 code groups included:

4333 hassoo—to send things [発送]
4362 jinin—personnel [人員]
4400 kaisi—beginning, commencing [開始]
4277 kookoo—navigate, to sail [航行]
4237 toochaku yotei—scheduled to arrive [到着予定]
4273 hatsu yotei—scheduled to leave [発予定]

There were vocabulary words associated with sailing schedules. According to training materials compiled at Arlington Hall, atesaki [宛先] was “destination” or “address”; chaku [着] was “arriving”; dai ichi [第一] was “first”; honjitsu [本日] was “today.” Maru [丸] was “commercial ship”; sempakutu [船舶通] was “ship” [-tu for 通行 tsuukou ‘traffic, passage’?]; sempakutai [船舶隊] was “convoy unit”; teihaku [碇泊] was “anchoring”; yori [より] was “from”; yotei [予定] was “schedule.” Gunkan [軍艦] was “warship.” Chu [中] was “now [or ‘in the middle of, i.e., underway’].” Hatsusen [発船] was “ship leaving.” Hi [日] was “day”; hongetsu [本月] was “this month”; senghu [sic; 船上 senjou?] was “onboard ship”; shuzensen [修繕船] was “ship being repaired”; tosai sen [搭載船] was “ship loading.”

Dot’s workday consisted of messages that, once deciphered, said things like “PALAU DENDAI/ 2/ 43/ T.B./ TRANSPORT/ 918/ (/878/)/ 20th/ 18/ JI/ CHAKU/ ATESAKI/ DAVAO/ SEMPAKUTAI/ 4/ CEBU/ E.T./”

Cracking the Japanese Water Transport Code

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 241-242:

Ambon. Canton. Davao. Haiphong. Hankow. Kiska. Kobe. Kuching. Kupang. Osaka. Palembang. Rabaul. Saigon. Takao. Wewak. Dot Braden until a few months earlier had never heard of most of these places. Now they ruled her life. They kept her running from the big table where she worked, over to the overlapper’s console, then back again to her spot at the big table. These were the names of places, somewhere in Asia or the South Pacific, likely to be mentioned toward the beginning of messages coded in 2468, the main Japanese water-transport code, or one of the other, smaller transport codes.

Or rather, they were some of the places. Transport code 2468 was massive; 2468 was everywhere; 2468 dominated the Pacific Ocean. Anything anybody needed was sent by water. Water was how the rice was transported, and the soldiers, and the spare airplane parts. To move the goods the Japanese Army needed, the marus were always sailing. Always leaving and arriving. A maru [丸] could be a tanker, a freighter, a cargo ship, a barge, a cable layer, a motor transport. [Japanese Navy ship names never use maru.] They plied between Hiroshima, Yokohama, Wewak, Saipan, Tokyo, Manila, the Truk Lagoon. Exotic places. It was not necessary for Dot to know how to pronounce the cities and ports, but it was helpful to know the four-digit code groups that stood for them. Code system 2468 commanded Dot’s attention, controlled Dot’s movements. It filled her brain.

A job more unlike teaching Virginia schoolchildren would be hard to imagine. No longer was Dot Braden standing at a chalkboard, explaining physics formulas to eye-rolling teenagers, or ordering senior girls to march and salute. Instead, she was sitting head down at a table puzzling over words she had never heard before she came to Arlington Hall. “Sono.” “Indicator.” “Discriminant.” “GAT.” The sono [‘that, aforementioned’] was the number appended to messages that had been divided into parts before being transmitted. Sono #1 was the first part, Sono #2 was the second part, and so on. The discriminant was the number that identified the system—for instance, 2468. The indicator was the tiny clue that told you what book to look in. GAT stood for “group as transmitted”: the code group plus the cipher. The GATs were what you saw when you looked at the message for the first time.

Dot, of course, was not to utter any of these words outside the high wire double fences of the Arlington Hall compound. People were warned never to use, outside the building, the words they used inside it. “This material is extremely secret and must be treated with the utmost care,” one training document said. “Some of the words which you will consider elementary have been used only in this code, eg KAIBOTSU SU ‘to sink a ship’ [海没す ‘sea-reject do’?]. If you should mention this word to any one connected with the Axis or in some way succeed in letting it get into improper hands, this one fact alone would betray to the Japanese that we are reading their most recent transport code.”

Code-breaking Triumph in the Solomons, 1943

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 200-201:

The Navy women had just missed taking part in the code-breaking triumph at Midway, but ten months later they were fully embedded for, and actively engaged in, the other great code-breaking event of the Pacific naval war. On April 13, 1943, a message came through along the E-14 channel of JN-25, addressed to “Solomons Defense Force, Air Group 204, AirFlot 26, Commander Ballale Garrison Force.” The code breakers weren’t able to recover the whole message right away, but the fragments they did recover suggested that the commander in chief of the combined fleet—Admiral Yamamoto himself—was headed to Ballale Island (now Balalae) on April 18. Intelligence officers concluded that this was an inspection tour.

The initial break was made in the Pacific, but Washington also got busy, recovering additives and code groups so that blanks could be filled in. More messages were intercepted, and the fast-working, far-flung teams exchanged findings. Among those digging out code recoveries was Fran Steen from Goucher. The inter-island cipher JN-20 “carried further details” about Yamamoto’s upcoming trip, so Raven’s crew of women were busy as well, adding facts and insights. Together the code breakers were able to reconstruct Yamamoto’s precise itinerary, which called for a day of hops between Japanese bases in the Solomon Islands and New Britain. Their translation concluded that the commander would “depart RR (Rabaul) at 0600 in a medium attack plane escorted by six fighters; arrive RXZ (Ballale) at 0800”; depart at 1100 and land at RXP (Buin) at 1110; leave there at 1400 and return to Rabaul at 1540, traveling by plane and, at one point, minesweeper. He would be conducting an inspection tour and visiting the sick and wounded.

It was an extraordinary moment. The Americans knew exactly where the enemy’s most valuable—and irreplaceable—naval commander would be, and when. Yamamoto was known for punctuality. Far above the pay grade of those working additive recovery, Nimitz and other top war officials decided Yamamoto would be shot down. It was not a light decision, assassinating an enemy commander, but they made it. The itinerary, as one memo later put it, signed the admiral’s “death warrant.”

In what was known as Operation Vengeance, sixteen U.S. Army fighter planes, Lockheed P-38s, went into the air on April 18, taking off from a Guadalcanal airfield. They knew Yamamoto would be flying in a Japanese bomber the Americans called a Betty, escorted by Zero fighter planes. The Americans calculated their own flight plan to meet the route they anticipated Yamamoto would be taking, planning to encounter him over Bougainville. They flew for so long that the pilots were getting drowsy; the white coastline of Bougainville was racing beneath them when one of the pilots broke radio silence and shouted, “Bogeys! Eleven o’clock!” There they were, on the horizon: six Zeros, two Bettys. The Japanese did not see the Americans at first, but once they did, the escorting Zeros moved to block the U.S. fighter planes, firing so the bombers could escape. There was a hectic battle in which it never became clear who had shot down whom, but one Betty bomber plummeted into the trees, the other into the surf. Yamamoto’s body was found in the Bougainville jungle, his white-gloved hand clutching his sword.

Cheering broke out at the Naval Annex when they heard the news. The architect of the Pearl Harbor attack was dead. The payback felt complete.

Cracking the Japanese Navy Code System, 1940s

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 88-90:

On June 1, 1939, the Japanese fleet began using a code that the Allies came to call JN-25. The Japanese—who had moved to using numbers rather than characters—now employed a massive codebook containing about thirty thousand five-digit groups. They also had a new way of enciphering. Before the code was sent, each code group was enciphered by using math to apply an “additive.”

Here is how the additive method worked: When a Japanese cryptographer began encoding a single message, he would look in the codebook and find the five-digit group that stood for the word (or syllable or phrase or punctuation mark) he wanted. He would repeat that process until he got to the end of the message. Then he would get out a different book, called an additive book, turn to a page—selected at random—pick a five-digit number, and add that to the first code group. He would add the next additive to the second. And so on. The Japanese code makers used a peculiar kind of math called noncarrying or “false” addition. There was no carrying of digits, so 8 plus 7 would equal 5, rather than 15. If the code group for “maru” was, say, 13563, and the additive was 24968, the resulting group would be 37421 (1 + 2 =3; 3 + 4 = 7; 5 + 9 = 4; 6 + 6 = 2; 3 + 8 = 1). That was the group of digits that would be radioed. To crack a message, the Americans had to figure out the additive and subtract it to get the code group. Then they had to figure out what the code group stood for.

Once again, it was Agnes Driscoll who diagnosed the new system. Neither she nor anybody in the Navy operation had seen an additive cipher—everything up to then had been transposition, or switching—but she figured it out. It took her less than a year to make a dent. A March 1 status report for the unit “GYP-1” stated that for the “5-number system”—an early title for JN-25—“First break [was] made by Mrs. Driscoll. Solution progressing satisfactorily.” She worked on it for several more months before being transferred in late 1940 to German systems—a promotion in the sense that the Atlantic was beginning to emerge as the hot spot. The research team continued working their way through JN-25, using her methods.

The process of stripping additives and discerning the meaning of code groups was laborious and excruciating. Years after World War II ended, American code breakers who worked in Hawaii and Australia were still arguing with their D.C. counterparts over what certain code groups stood for. Much like the women who trained the men who would get to do the wartime flying, much like Elizebeth Friedman over at the Coast Guard, Agnes Driscoll taught the men in the field who did this. “In the Navy she was without peer as a cryptanalyst,” wrote Edwin Layton, who headed naval intelligence for Admiral Nimitz, the chief naval commander in the Pacific during the war. In December 1940, both code and cipher were changed, to a system the Allies called JN-25B; the team stripped the additives and built a partial bank of code words. Then, in early December 1941—days before Pearl Harbor—the additive books were changed. The codebooks were not. The U.S. Navy was able to recover a certain amount of the new system—but not enough—before the attack on Pearl Harbor happened and all hell broke loose.

“If the Japanese Navy had changed the code-book along with the cipher keys on 1 December 1941, there is no telling how badly the war in the Pacific would have gone,” said Laurance Safford.

As crushing as Pearl Harbor was, it was thanks in large part to Driscoll’s decades-long detective work—and to the example Elizebeth Friedman set for other women—that America did not enter the Second World War quite as blind as it might have seemed.

The 1941 Boom in U.S. Codebreaking Jobs

From Code Girls, by Liza Mundy (Hachette, 2017), Kindle pp. 22-25:

During World War II, code breaking would come into its own as one of the most fruitful forms of intelligence that exists. Listening in on enemy conversations provides a verbatim, real-time way to know what that enemy is thinking and doing and arguing about and worrying over and planning. It provides information on strategy, troop movements, shipping itineraries, political alliances, battlefield casualties, pending attacks, and supply needs. The code breakers of World War II advanced what is known as signals intelligence—reading the coded transmissions of enemies, as well as (sometimes) of allies. They laid the groundwork for the now burgeoning field of cybersecurity, which entails protecting one’s data, networks, and communications against enemy attack. They pioneered work that would lead to the modern computing industry. After the war, the U.S. Army and Navy code-breaking operations merged to become what is now the National Security Agency. It was women who helped found the field of clandestine eavesdropping—much bigger and more controversial now than it was then—and it was women in many cases who shaped the early culture of the NSA.

The women also played a central role in shortening the war. Code breaking was crucial to Allied success in defeating Japan, both at sea and during the bloody amphibious assaults on Pacific islands against a foe that was dug in, literally—the cave fighting toward the end of the war was terrible, as were kamikaze attacks and other suicide missions—and willing to fight to the death. And in the all-important Atlantic theater, U.S. and British penetration of the Nazi Enigma cipher that German admiral Karl Dönitz used to direct his U-boat commanders helped bring about the total elimination of the Nazi submarine threat.

The chain of events that led to the women’s recruitment was a long one, but a signal moment occurred in September 1941, when U.S. Navy rear admiral Leigh Noyes wrote a letter to Ada Comstock, the president of Radcliffe College, the women’s counterpart to Harvard. For more than a year the Navy had been quietly recruiting male intelligence officers from elite colleges and universities, and now it was embarking on the same experiment with women. Noyes wanted to know whether Comstock would identify a group of Radcliffe students to be trained in cryptanalysis. He confided that the Navy was looking for “bright, close-mouthed native students”—that is, high-achieving women who had the sense and ability to keep a secret and who had been born in the United States and were free of close ties with other nations.

“Evidence of a flair for languages or for mathematics could be advantageous,” Noyes said, adding that “any intense sociological quirks would, of course, be undesirable.” Without stating what such “quirks” might be, the admiral suggested that a handful of promising seniors could enroll in a training course the Navy had developed.

“In the event of total war,” Noyes told her, “women will be needed for this work, and they can do it probably better than men.”

Ada Comstock was happy to comply. “It interests me very much and I should like to take whatever steps would be thought serviceable,” she promptly wrote to her friend Donald Menzel, an astronomy professor at Harvard who was serving as a point person for the broader naval recruiting effort. Astronomy is a mathematical science and a naval one—for centuries, navigation was done using the position of the sun and the stars—and many of the instructors who taught the secret course would come from the field.

…

At the Navy’s request, Comstock also approached leaders of other women’s schools. These deans and presidents were devoted to the cause of educating women and eager to defend liberty and freedom of thought against fascism and totalitarian belief systems. They also were keen to develop career opportunities for their students. The leaders savvily perceived that war might open up fields—and spots in graduate schools—that up to now had been closed to women. Even before Comstock received the Navy’s letter, many of the leaders had been strategizing over how they could provide what Virginia Gildersleeve, dean of Barnard College, called “trained brains” to a war effort that would depend on advances in science and math.

The women’s college leaders met at Mount Holyoke on October 31 and November 1, 1941, with representatives from Barnard, Bryn Mawr, Vassar, Wellesley, Radcliffe, Smith, and Mount Holyoke attending. Comstock told them about the Navy’s request and said Radcliffe would participate. She distributed some materials the Navy had developed: a “Guide for Instructors” and an “Introduction to Students.” The idea was that selected students would take the course during the remainder of their senior year, then go to work for the Navy, in Washington, as civilians. The “Guide for Instructors” assured them that no prior experience was necessary and that they would receive a “gouge,” or answers to the problems. The instructors would be given a few texts to jump-start their own education, including a work called Treatise on Cryptography, another titled Notes on Communications Security, and a pamphlet called The Contributions of the Cryptographic Bureaus in the World War—meaning World War I, the so-called war to end all wars.

The result was the wave of secret letters that appeared in college mailboxes in the fall of 1941, summoning surprised young women to secret meetings. Most were in the top 10 percent of their class, selected based on academic performance as well as character and loyalty and grit.

Wordcatcher Tales: hen’i kabu ‘mutant strain’

In its Japan Focus section this week, the Honolulu Star-Advertiser introduced a new term that has been much in the Japanese news lately. Their romanization as “hen ikabu (n.) mutant strain, as in COVID-19 variants” would be more accurately rendered as hen’i 変異 ‘mutation’ + 株 kabu ‘stock, strain’. Let’s break it down a little further.

変 hen ranges in meaning from ‘change’ to ‘accident’ to ‘strange’, as in 変名 henmei (change-name) ‘alias’, 変成 hensei (change-become) ‘metamorphosis’, 変死 henshi (accident-death) ‘accidental death’, or 変態 hentai (strange-condition/attitude) (n.) ‘metamorphosis’, (adj.) ‘abnormal, perverted’. Most foreigners resident in Japan soon learn the expression 変な外人 hen na gaijin ‘strange foreigner’.

異 i also means ‘strange, different, foreign’, as in 異人種 ijinshu (alien-person-type) ‘alien race’, 異見 iken (different-view) ‘objection’, 異国語 ikokugo (foreign-country-language) ‘foreign language’.

株 kabu ‘stock, strain’ originally meant ‘rootstock’, as in kabu ‘turnip’ (now written 蕪) but nowadays most commonly means ‘stock, share’, as in 株主 kabunushi ‘shareholder’ or 株式会社 kabushiki kaisha ‘joint stock corporation’. In Japanese corporate names, K.K. is equivalent to Corp., Inc., or Ltd.
