The Korean War of 1592-1598 was a major conflict between Japan and the alliance of Ming of China and Joseon of Korea. Japan invaded Korea on May 23, with the larger objective to conquer the entirety of Asia (and the whole world)[1] by using Korea as a land bridge to China. The battles that involved 300,000 combatants and claimed more than 2 million lives took place almost entirely on the Korean peninsula and its nearby waters. The war consisted of two main invasions from Japan – the first in 1592 and 1593, and the second from 1597 to 1598.

Toyotomi Hideyoshi, the predominant warlord in Japan, had for long been aspiring to leave his name in history as a great conqueror of Asia. Even before unifying all of Japan in 1590, Hideyoshi in 1587 began sending ambassadorial missions to Korea in order to threaten her to submit and to join with Japan on war against China. However, since Hideyoshi relied on the Tsushima Island as his main diplomatic channel to Korea, and the Tsushima Island was a major beneficiary of the trade between Korea and Japan under peaceful relations, most of Hideyoshi's message failed to go through to the Korean side. The Koreans sent a friendly embassy to Japan, but Hideyoshi mistook the mission as the Korea's gesture of surrender. When the Korean embassy returned with a letter directly from Hideyoshi revealing his intentions for a global conquest, the Korean court wrote to Hideyoshi a reply scoffing him for pursuing such an impossible goal. Hideyoshi replied and threatened the Koreans with another letter, and, when the military preparations were completed and the Koreans did not respond, he launched the invasion late in May of 1592 and commanded his forces in absentia.

The Japanese troops first attacked the southeastern part of Korea and then advanced northwestward to the capital. The Korean capital city of Hanseong fell within 3 weeks and most of the peninsula came into Japanese control by the end of the year. China responded by sending 5,000 troops to the city of Pyeongyang in late August, but the Chinese were horribly outnumbered and defeated by the Japanese troops. However, within a few days of the Chinese defeat, the Korean admiral Yi Sun-sin annihilated the Japanese fleet carrying the reserve troops that would continue the invasion into China. On January 1, 1593, the Chinese launched a counter-offensive with 30,000 troops and reclaimed Hanseong by the middle of May. With the southeastern parts of the peninsula in Japanese possession, the two sides spent several years in diplomatic talks; the Japanese officials justified their invasion by asserting that Korea carried out policies to prevent Japan from entering the Chinese tributary system. Consequently the Chinese diplomats went to Japan and invested Hideyoshi, whose subordinates misled him into believing that the Chinese had come to surrender in person. The peace negotiations culminated in another invasion of Korea by the Japanese troops in October of 1597 when Hideyoshi found out the truth behind the Chinese visit and was greatly offended. The second invasion saw very little action, and the Japanese troops, as ordered by Hideyoshi, began to withdraw late in 1598.[2] The war ended middle in December with the naval battle at the straits of Noryang, where the Korean and the Chinese fleets sunk over 300 Japanese ships costing as many as 10,000 lives.

The war is known by several English titles, including the Hideyoshi's invasions of Korea, in context of Hideyoshi’s biography; the Seven Year War, in reference to the war’s duration (the fighting continued even during the peace negotiations); and the Imjin War, in reference to the war's first year in the sexagenery cycle (in Korean).[3] The Koreans call the war "the bandit invasion of the year Imjin (water dragon)". The various Japanese titles include the "Korean War", and the "Pottery War" and "War of Celadon and Metal Type" (in reference to the ceramic and metal printing technologies and booties that the returning Japanese soldiers brought home from the war). The Chinese generally use "the Korean Campaign" to refer to the war.[1]

East Asia and the Chinese Tributary System

East Asia in the 16th century.

The war took place within the context of the Chinese tributary system that dominated the East Asian geopolitics. In practice, the tributary states periodically sent ambassadors to the Chinese imperial court to pay homage and to exchange gifts, while maintaining complete autonomy. Many of the tributary states received from China the rights toward the international trade within the tributary system. The theoretical justification for the tributary system was the doctrine of the Mandate of Heaven, that the Heaven granted the Chinese Emperor the exclusive right to rule, with the purpose of benefiting the entirety of mankind.[4] Several Asian countries, including Korea,[5][6] voluntarily joined the tributary system in pursuit of the legal tally trade and the legitimacy of their rule through the doctrine of the Mandate of Heaven.

Japan actively sought to engage in the tributary trade and attained with China two treaties, in 1404 and in 1434, that admitted Japan into the tributary system and required Japan to police its waters against the wako pirates. However, as the Japanese lords failed to effectively control its piracy, China expelled Japan from the tributary system in 1547.[7] The trade issue would emerge again, during the wartime negotiations between Japan and China, as a cautious excuse from the Japanese to justify their first invasion of Korea.

China came to Korea's aid during the war mainly because of Korea's symbolic importance to the Chinese. The Chinese and Koreans considered themselves as the pinnacles of civilization, similarly to today's cross-national cultural identities (such as "the West") based on scientific and academic achievements.[8] The very strict Confucian ideologies that imbued the two countries contributed to this elitism by rejecting the foreign customs and learnings as immoral and barbaric. Additionally, China had to fulfill its promise to provide security to its tributary states. The Chinese authorities feared greatly that the China's loss of legitimacy on this occasion would spur a domino effect of opposition, collapsing the entire tributary system.[9] And lastly the Japanese invasion posed threat to their own security, since Hideyoshi had proclaimed that he aimed to attack China after occupying Korea successfully, and the loss of Korea to Japan meant that China could no longer outflank the northern region of Manchuria inhabited by the hostile Jurchen tribes.[10]

Military situations of Japan, Korea, and China

This conflict played out to be one of the earliest cases of modern warfare in Asia, and easily surpassed any of the contemporary conflicts in the European theater in terms of the size of the armies, the technologies, and the tactics deployed. The Sino-Korean alliance and the Japanese deployed a combined sum of more than 300,000 troops across the peninsula - the best equivalent in Europe was the conflict between Spain and England in 1588 involving 30,500 Spaniards and 20,000 English.[1] Superior technology of the Sino-Korean militaries heavily contributed to the Japanese retreat from the peninsula by 1598.[11]

An illustrative example of the war's modern attributes is the participants' considerable use of the European guns, first brought to Japan in 1543 by the Portuguese traders on the island of Tanegashima. Upon introduction, the Portuguese arquebus (slightly smaller than a musket) deeply impressed the Japanese, who had experienced by then more than a century of civil war. Within few years, several hundred tanegashima (as they were first called)[12] were locally produced in Japan, and, by 1556, 300,000 guns existed in Japan.[13] The new weapon was much more affordable than the bow and arrows because the round lead-bullets were cheaper to produce than the crafted arrows, and skilled archers were rare and expensive while any men could be trained as gunners under cheap pay. The arquebus had a range of nearly half a kilometer and a penetrating power strong enough to pierce iron armor at close range.[14] The Japanese observed several inconveniences with the new long-ranged weapon, including the slow loading time between each shot and its poor accuracy. A warlord named Oda Nobunaga overcame the deficiencies by arranging his men to fire their guns in concentrated volleys, and conquered with success a third of Japan before his assassination in 1582. Toyotomi Hideyoshi, one of Nobunaga's followers who came out to be successful in the ensuing power struggle, continued Nobunaga's conquest up to the unification of Japan in 1590.

By the end of civil war in Japan, Hideyoshi had built up an army of 500,000 veteran troops. The army consisted mostly of infantry and partly of cavalry, and the infantry further divided into archers, spearmen, and gunners. The flawed, conventional view of the war in brief is that the Japanese, superior to the allies tactically and technologically (mainly by the muskets), were winning the war until Admiral Yi developed the (possibly iron-clad) turtle ships and the Chinese came to the Korea's aid and outnumbered the Japanese. There are several reasons why this perspective became dominant. First the Japanese chroniclers who worked for the Japanese commanders often exaggerated the accomplishments of their employers and inflated the number of enemies. Second, in Korea and China, the established historiographical practices limited the historians to a framework of praise and blame in their analysis, and made inevitable their emphasis on the military weakness of Sino-Korean alliance. And third, these early misinterpretations provided a firm basis for the later scholars to continue the myth of Japanese victory.[15]

In fact, the Korean troops were, on the most part, very poorly organized, equipped, and trained. The 200 years of relative peace in Korea necessitated the Joseon government to keep only a few active military units. In contrast to the Japanese chain of command, the higher-ups of the Korean military tended to consist of officers with political connections more than individuals of merit. Several scholar officials within the king's court attempted to push military reforms, such as a nationwide increase of regular troops to 100,000 and an implementation of the matchlock guns brought as a gift by a Japanese ambassador (see below); however, such voices were lost in the constant political battles waged by the two dominant factions within the king's court. Thus the Joseon military could deploy only a total of 84,500 troops throughout the first invasion[16] against the Japanese sum of 200,000[17] (initial force of 150,000 plus reinforcements).

China had its own problems with its military. Because the Chinese military farmed and provided for itself during peacetime, the garrisons became domesticated and became comparable to "an undisciplined mob".[18] These mobs readily fled in battle unless they were threatened by their own officers, and they looted their civilian populations regardless. Corruption allowed for frequent desertions while keeping the figures overblown at 2 million men. The generals profited by submitting inflated number of troops to Beijing and securing some of the surplus payments for themselves. The lower-ranking officers, who were often literate half-way or could not read at all, took little interest in learning the military tactics and disciplining the troops, but they eagerly killed non-combatants in battle to increase their head counts and turned defeats into victories.[19]

On the other hand, China and Korea were ahead of Japan in all areas of military technologies (except in the manufacture of lighter and sharper swords[20]). China had always been a major source of new military inventions like gunpowder and rockets for the rest of Asia, and, since the military ascendancy of the European countries in the 16th century, the Chinese reproduced and adopted whatever new weapons that they could find on the European trading vessels that entered their country.[21] Some of the very interesting weapons in the Chinese arsenal included the crossbows,[22] smoke bombs, hand grenades, battering rams loaded with gunpowder,[23] and mortars that fired up to 100 missiles per discharge.[24] There is some evidence indicating that the Chinese invented bulletproof armor during this period to counter the Japanese muskets.[25]

The Koreans began their gunpowder tradition in the late 14th century during the Goryeo Dynasty, when they cracked the secrets to make black powder, and developed rockets and cannons based on existing models in China. The Koreans experimented on their own, bringing about such local inventions as an anti-ship wooden missile, a primitive multiple launch rocket system (MLRS) called "hwacha", and the delayed-action explosive iron shell, which contained an internal explosive charge with time delay fuse. (Unlike the conventional round shots without explosive charge, the delayed-action shells could be fired over fortifications to explode and to blindly hit the enemies inside.)[26] The technological differences between the Japanese and the allies were such that the Koreans could immediately manufacture the match-lock guns of the Japanese on the event of the war but the Japanese could not compete with the allies in the production and deployment of artillery.

The allies' lead in the artillery would prove to be most fatal to the Japanese at sea. The Japanese fought naval battles mainly by boarding enemy ships and fighting as if on land. To the contrary, the allies rightly understood that it was more effective to sink the enemy vessels than to kill the individual combatants on-board, and therefore the naval gun came to be an indispensable part of the Korean and the Chinese navies. Consequently, the allies could bombard the Japanese vessels, most effectively in tight channels of water where the Japanese ships could not spread out and were most susceptible to the concentrated fire of the allies' cannons. Furthermore, the Japanese deployed the little amount of cannons that they made or stole from the allies without strategy or experience; for example, the Japanese suspended some of their cannons on ropes and thereby reduced their accuracy significantly.[27]. Even when the Japanese would attempt to increase the strength of their artillery at sea, their ships would be naturally unable to hold as many cannons as the allies' vessels. The Japanese ships were mostly transports built lightly for maximum speed and minimum production cost, and therefore most of them lacked the stability and the structural strength needed to endure the concentration of cannons on the same level as the Korean and the Chinese ships.[28]

The Korean ships had a different bottom layout from the Chinese and the Japanese ships.

The differences in the shipbuilding techniques of the allies and the Japanese also contributed to the superiority of the allies' ships in terms of stability, maneuverability, and solidness. For example, the Japanese (and also the Chinese for some of their ships) adopted "V"-shaped hulls to increase speed of their vessels, but the Koreans had to build their ships on rectangular bottoms so that, during low tide, they may "sit" on sand.[29] The underwater geography around the Korean peninsula was flat, and therefore the Korean coastlines experienced fast tides that vacillated over a huge littoral span. The boxy design reduced the speed of the Korean ships but fared much better than the "V"-shaped hull in terms of stability and maneuverability. The Japanese further compromised their ships' maneuverability with their use of the single, square sails, which, unlike the the fore and aft sails of the Chinese and the Korean ships, were useless without good winds.

In summary, Japan had fully mobilized for the war, and her troops were professional and well-equipped; China and Korea lacked preparations, and their military bureaucracies were corrupt. In the first half of the war, the Japanese did not win as much with their guns as the Koreans lost with fewer men, little to no training, and not enough of their cannons and rockets. It is interesting to add that the Japanese guns with a maximum range of 600 yards did not completely outdate the Koreans' composite-reflex bows with a similar limit of 500 yards (the Japanese bows had a range of 350 yards).[22] Rather, this difference of 100 yards multiplied considerably in the hands of untrained Korean peasants. When the Chinese joined the Koreans, they poured the advanced machines into the conflict in a full scale that the Koreans had not achieved before, and countered the multitude of Japanese muskets with a handful of their heavier cannons.[30] Technology then tied the war and eventually gave way to victory for the allies.

Pre-War embassies and preparations

Toyotomi Hideyoshi at the tea arbor in Fushimi Castle.

Toyotomi Hideyoshi succeeded in pacifying Japan through his conquests. Warlords no longer wasted men and resource in the endless feuds, but united behind Hideyoshi for the single goal of unification and the promise of more lands. But Hideyoshi realized that he would inevitably run out of new lands to conquer in Japan. The idle warlords would again engage in internal power struggles, unity would disappear, and Hideyoshi would lose power. Thus, even before he unified all of Japan, Hideyoshi looked outward to keep his military machine running. Hideyoshi said in 1585, "I am going to not only unify Japan but also enter Ming China."[31]

Hideyoshi had pretty good reasons to believe that China could be won within his lifetime. First, Hideyoshi observed that the the Chinese were unable to protect the seas against the Chinese and Japanese pirates. Second, Hideyoshi believed that China's lack of interest in keeping Japan within the tributary system also indicated Ming's weakness because, as a military dictator himself, Hideyoshi could not imagine otherwise.[32] Third, Hideyoshi gathered clear evidence of Korea's weakness when in 1587 he sent 26 ships to the southern parts of the peninsula to test the defenses.[21] Hideyoshi believed that he could blitzkrieg across the Korean peninsula toward Beijing and drive the entire tributary system into his hands.[32]

In his past winning experiences, Hideyoshi offered his enemy a chance to surrender before engaging in battle, and Hideyoshi planned to bestow that same benevolence to Korea. It was simply a logical response that Hideyoshi developed to his successive repeats of complete annihilation for his opponents, and the method worked for most of the time in Japan. Hideyoshi seemed pretty positive that the wise Koreans would also surrender to his threats of invasion. But there was no way that the Koreans would take Hideyoshi seriously. Not only were the Koreans unaware of the recent developments in Japan, just as Hideyoshi, too, knew little of the outside world, but the Koreans already had a long-established idea of where Japan stood in the world order. The Chinese and the Koreans saw the Japanese as uncivilized and arrogant. Again and again, the Koreans would find the Japanese behaviors to be rude and contrary to the Chinese practices; for example, the Japanese would surprisingly refer to their powerless emperor with the Chinese character reserved solely for the Chinese Emperor, the son of Heaven.[33] The Koreans also found Japan's status as a country to be questionable, since the emperor was simply a figurehead and his subjects with actual power always waged wars amongst themselves.

Hideyoshi ordered So Yoshishige, the daimyo of the Tsushima Island, to carry out the diplomacy with the Koreans. Since all trade and diplomatic ships between Japan and Korea had to pass through the "Tsushima gate", So was very well aware of the Korean situation and was positive that Hideyoshi was bound to fail with his approach.[34] So was not sure whether Hideyoshi truly intended to invade Korea or was just bluffing, and So had a vested interest to keep the Japanese-Korean relations at its best so that his family would continue to oversee and benefit from the free trade between Japan and Korea. The Koreans had designated the Tsushima Island as the only gateway between Korea and Japan (all traffic coming from elsewhere would be considered hostile), put the So family in charge of regulating the traffic, and gave them a regular income and the right to levy trading fees. So Yoshishige therefore molded Hideyoshi's first message to the Koreans as a request to re-establish diplomatic relations with Japan[35] rather than a demand to submit and send tributes. And, in 1587, So sent a family retainer, Yutani Yasuhiro, to convey the modified message to the Koreans. However, the Koreans sent away the envoy with a note that they would not dispatch an embassy to Japan. The Koreans disliked Yutani, a big and old veteran of the Japan's civil war who knew nothing about diplomacy and courtly manners, and they found Hideyoshi's letter to be rude, even with So's more refined touch. Again the Koreans at the capital court reaffirmed their negative perception of the Japanese.[36]

Hideyoshi was outraged with the Koreans' response. He accused Yutani of collaborating with the Koreans and killed him along with his entire family. So Yoshishige lost his position as the daimyo of Tsushima, and So Yoshitoshi, who was the adopted son of Yoshishige and the son-in-law of Konishi Yukinaga, was put in his father's place: Hideyoshi felt that So Yoshitoshi was more dependable because Konishi was one of his most trusted generals. Late in 1588, Hideyoshi ordered So Yoshitoshi to carry out another embassy to the Korean court. So himself led 25 men to the Korean capital and reached there by February of 1589; So took care to have with him an old Buddhist monk, Genso Keitetsu, so that his scholarship may impress the Koreans. This time, So presented Hideyoshi's letter in its original form:[36]

Portrait of King Seonjo.

When my mother conceived me it was by a beam of sunlight that entered her bosom in a dream. After my birth a fortune teller said that all the land the sun shone on would be mine when I became a man, and that my fame would spread beyond the four seas. I have never fought without conquering and when I strike I always win. Man cannot outlive his hundred years, so why should I sit chafing on this island? I will make a leap and land in China and lay my laws upon her. I shall go by way of Korea and if your soldiers will join me in this invasion you will have shown your neighborly spirit. I am determined that my name shall pervade the three kingdoms.[36]

Having read the letter, the Korean King Seonjo and his officials discussed how they should respond to Hideyoshi. Recalling that Hideyoshi previously asked Joseon to re-establish diplomatic relations with Japan (that's how So Yoshishige had presented Hideyoshi's demands), the Koreans decided to send a good-will embassy to Japan. The Koreans believed that Hideyoshi's belligerence as an outsider would go away once they treat him with recognition and welcome him into the sinocentric world order. The Korean envoys would also take the occasion as an opportunity to gather intelligence on the recent developments in Japan.[36] The Joseon court informed So Yoshitoshi that they would send ambassadors to Japan on a friendly visit but upon one condition - that the Japanese return the Korean criminals who fled the previous year to Japan, after they collaborated with Japanese pirates to attack their fellow Koreans. So agreed, and one of his men went to Japan in search of these people. He returned with 10 of those who fled and many more who were taken as prisoners.[36]

With the condition having been met, the Koreans agreed to send an embassy to Japan, and they allowed So Yoshitoshi to see King Seonjo for the first time. In his meeting with the Korean king, So received a fine horse as a gift and presented in return a peacock and some arquebuses[36] (as mentioned previously, the Koreans neglected this early chance to manufacture and distribute this new weapon). Since winter was approaching and the embassy would have to wait until the spring of the following year, the Joseon court took the time to debate and pick the ambassadors for the mission to Japan. With Hwang Yun-gil of the Western Faction and Kim Song-il of the Eastern Faction having been named the chief ambassador and the vice ambassador respectively, the embassy set out in April of 1590 with So Yoshitoshi's party in their company.[37] Not much happened during the 4 months of the journey except that the Koreans were again bothered by the different Japanese customs, and especially the vice ambassador concerned himself with the differences by criticizing endlessly. For example, on a stop at the island of Tsushima, Kim refused to attend a feast prepared by So Yoshitoshi on the ground that the Japanese let the Koreans in on sedan chairs rather than on foot. So apologized and immediately killed his sedan bearers to appease the vice envoy.[37] The Korean embassy arrived in Kyoto (used to be Japan's capital) in August of 1590, and waited for Hideyoshi to return from his campaign in the Kanto region. Even when Hideyoshi came back triumphant in October, Hideyoshi would meet the Koreans in December because, in the meanwhile, he tried unsuccessfully to win Emperor Go-Yozei's presence in order to impress the Koreans of his own status.[37]

The Koreans were bemused by their strange meeting with Hideyoshi. There was no extravagant banquet that the Koreans were familiar with in their typical diplomatic exchanges. The Koreans presented their letter from King Seonjo to the "King of Japan", and a plate of rice cakes and a bowl of wine were passed around for everyone present to share. With all seated in complete silence, Hideyoshi left the hall and reappeared with his son Tsurumatsu. Moving freely around the hall and cooing to the child, Hideyoshi ordered that music be played. Then, when the baby urinated on his clothes, Hideyoshi laughed and went away with the baby.[37] Shortly thereafter, So Yoshitoshi and the monk Genso led the Korean envoys to the port of Sakai, near Osaka, to wait for Hideyoshi to write a reply to King Seonjo. So far, the Koreans were totally unimpressed with Hideyoshi and wondered why they ever came to Japan. Hideyoshi was short and ugly, he was common in his clothes and in his treatment of the Koreans, and he was only a "kampaku" or a regent, not even a king. For the Korean King to have addressed a Japanese regent as an equal was absolutely humiliating and inappropriate.[37] But for Hideyoshi, it was different. The Joseon court had sent a tribute mission to show their submission to Japan. It was necessary for Hideyoshi to make clear to the Koreans the absolute power that he possessed despite his status as a regent. Hideyoshi could have easily impressed the Koreans by holding a feast that was expected of him, but Hideyoshi decided to defy that very expectation. In contrast to his superior emperor, who must abide by customs and duties, Hideyoshi ruled above all conventions.[37]

The Korean ambassadors returned to Seoul with Hideyoshi's letter in March of 1591. The letter thanked King Seonjo for sending a "tribute mission" and ordered Korea to prepare to war against China. The letter originally contained the phrase, "surrendering to the Japanese court", but the Koreans had it removed back in Sakai. The Joseon officials discussed at length the appropriate measures that they should implement in response to this letter. Hwang, who headed the embassy to Japan, asserted that Japan was fully prepared for war; the vice ambassador Kim strongly disagreed. In fact, the two envoys had gathered only a small bit of useful intelligence, and the court officials argued this question of how much danger Japan posed mostly for the sake of party politics. Since Kim's Eastern Faction now held the edge over the previously dominant Western Faction, the debates came to the conclusion that Hideyoshi posed no real threat to Korea.[37] The Joseon court sent a firm reply to Hideyoshi, admonishing him for failing to "understand...[his] situation as well as...[Korea's]". Hideyoshi also sent So Yoshitoshi back to Korea with his ultimatum: submit or be destroyed.[38] So hastily handed Hideyoshi's letter to the Korean authorities at the port of Busan, but the Koreans at the capital court doubted its authenticity on the basis that the letter was not presented directly to the court by a Japanese envoy.[39]

As a vassal state, the Koreans had to report to China on their recent exchange with Hideyoshi. However, some Korean officials feared that China would become irate upon finding out that Korea carried out diplomacy with Japan without China's consent. Others argued that, even if they were to keep silent about Hideyoshi, China might find out about Hideyoshi's intentions through other channels within its tributary domain and may suspect Korea to be in accord with Hideyoshi. In fact, as early as 1591 the Chinese had heard of Hideyoshi's plans for invasion, first from the Ryukyu Islands, and were waiting for the "Little China" to notify them. Luckily, the Inspector General Yun Tu-su wrote an individual report about the "rumors" of Hideyoshi's plans for war and had it carried to the Chinese by the Ambassador Kim Ung-nam on his tribute mission to Beijing. Although the situation in China was ameliorated, Yun was exiled to the countryside for overstepping his authority.[40]

Daenammum fortress on the Bukhansan mountains. The walls of these "mountain castles" (san-sung) were too long and hard to defend.

The Koreans also took steps to strengthen their defenses. The capital court dispatched orders to restock local arsenals, fortify fortresses, and conduct several months of required training. However, most of the able male population avoided the drills through ways of bribery and left the weak, young or old, and vagabonds searching for free meals to fill their ranks. People resisted the other mandatory programs because the new duties seemed like another form of government taxation, and they already had enough trouble with the poor harvests from the previous years. Many projects were abandoned incomplete, and the constructions that did finish were too large to be defended effectively.[41]

Meanwhile, all of Japan prepared for total war, amassing an army of 235,000 troops at Nagoya (present-day Karatsu). Hideyoshi built an invasion headquarters often referred to as the "Nagoya Castle" (different from today's Nagoya Castle that was built later on), and gathered troops from all parts of the country. Because longer travels cost more, Hideyoshi required more troops and supplies from the daimyo lords who were closer to Nagoya than the lords who were farther away. Hideyoshi also required less of the less trustworthy daimyos in fear that they might rebel when they find their servitude to be too burdensome.[42] In fact, a total of 335,000 men were mobilized nationwide, but 100,000 troops remained in Japan to fill in the holes left by the invasion troops. 75,000 of the 235,000 troops at Nagoya would guard the invasion base against a possible Chinese invasion, and only 158,800 men would sail to Korea.[42] Hideyoshi built a total of 700 transports at Kyushu, Shikoku, and Chugoku, and had Kuki Yoshitaka make several hundred battleships at the Bay of Ise on the eastern side of Honshu. Also in 1586 Hideyoshi had obtained promise of a Portuguese Jesuit, who thought that Hideyoshi was merely bluffing, to lend 2 men-of-war for use in the war, but, as of 1592, the Portuguese authorities refused to lend their warships to the regent.[42]

First invasion

Template:Collapsible Info Table on Troops Division On the afternoon of May 23, 1592, Konishi Yukinaga commanding the First Division of 18,700 men set sail from the Tsushima Island. Hideyoshi had originally planned the launch of his invading forces to begin on April 12, as he had with his Kyushu campaign in 1587 and the Odawara Siege in 1590, but he reprieved the zero hour to April 21 for 3 reasons. First, his troops needed more time to assemble at Nagoya and the islands of Iki and Tsushima. Second, So Yoshitoshi had yet to report whether the Koreans would ally or war with him (and he never would). Finally, Hideyoshi was too sick to make the visit to the Emperor that was required for him to go to war. Finally on April 24, Hideyoshi sent orders to commence operation, and, on May 7, he himself left Kyoto and headed for Nagoya.[43]

By the time of the invasion, the first 3 divisions of Hideyoshi's army that were to start the invasion were stationed at Tsushima while the rest of the forces remained at Nagoya. Of these 3 groups, Konishi Yukinaga's First Division were to invade first and secure the port city of Busan. Although the First Division's mostly light transports were supposed to wait for a fleet of warships to come and provide protection, Konishi disregarded them and landed all of his 400 transports off of the Busan shores by the nightfall of May 22.[43]
