In 1274 and Again in 1281 the Tried Without Succes to Invade Japan

In the late thirteenth century, the Mongol Empire under Kublai Khan made ii unsuccessful attempts to invade Nihon. Historian Kawai Atsushi gives the groundwork to the invasion, examines different theories about reasons for its failure, and looks at the aftermath for both sides.

Emissaries Ignored

In November 1274, a fleet conveying some 30,000 Mongol Empire troops approached Hakata Bay off the Japanese island of Kyūshū. Genghis Khan had established the empire in the early thirteenth century by unifying the nomadic peoples of the Mongolian Plateau. Successive leaders expanded the empire through central Asia, and made Goryeo (Korea) a vassal state in 1259. At the time of the invasion, the Mongol holdings stretched from western Asia and Russia to northern Communist china and the Korean peninsula.

Seeking a southern base, in 1264 Kublai Khan had moved the capital from Karakorum to the new city of Khanbaliq (now inside the modernistic city of Beijing). Kublai, the fifth Mongol emperor and a grandson of Genghis Khan, then founded the Chinese Yuan Dynasty in 1271. Around this time, he was warring with the Southern Song Dynasty, which had its majuscule in Lin'an (now Hangzhou). He sent emissaries to Nihon in an try to break its shut merchandise ties with the Southern Song and reduce the latter's economic forcefulness.

Kublai'southward letter to Nippon talked of how it had previously sent emissaries to Communist china, but had not washed and so since his rise to power. He invited the land to send emissaries again and establish friendly relations. It seems that at commencement he had no intention to transport troops to occupy Nihon, but the letter concluded with what could be taken as a threat that he might if the island land did non submit as a vassal.

When the shogunate passed the letter on to the imperial courtroom, which handled international diplomacy, the court decided to make no reply. The shogunate relayed this to the Yuan (Mongol) emissaries staying in the Kyūshū city of Dazaifu, and sent them domicile. All the same, Kublai continued to send emissaries, but the shogunate ignored them. Why did it decline diplomatic relations with the Yuan Dynasty?

Historian Arai Takashige writes, "The administrators of this time knew virtually naught of international weather, and had shut to goose egg experience of contact with other states. With this ignorance and inexperience, when they were faced with the alphabetic character, they must take simply frozen. And their inexperience meant they were too unversed in diplomatic technique."

Certainly, if the government had been aware of the immense size of the Yuan territory and how much more than powerful the empire was than Japan, it could not have ignored this. But the shogunate got its information from Zen monks and their disciples from Southern Song, and it is not inconceivable that they might have downplayed the size of the Mongol Empire to protect their ain interests, muddying the judgement of Nihon's statesmen.

A Mismatch in Tactics

Impatient at the lack of response, Kublai sent an invasion fleet conveying thirty,000 troops (twenty,000 Mongol soldiers and x,000 from Goryeo), which entered Hakata Bay on the dawn of Nov 26, 1274. Partly due to inadequate preparations, the disorganized shogunate soldiers on the scene allowed the Yuan forces to state without difficulty. In the battle that followed, the shogunate was at an overwhelming disadvantage, mainly due to the different tactics of the two forces. While the Kamakura samurai hoped to engage in one-to-i horseback combat, the Yuan soldiers acted in groups.

As samurai approached the enemy to brand individual challenges, they were immediately surrounded and shot down. In addition to the unsuitability of this grade of battle for the Japanese side, the Mongol soldiers' brusque bows had greater range than those of the Kamakura combatants and their arrows were tipped with toxicant, making even glancing hits fatal to the Japanese. Horses also equally soldiers came nether attack.

Alongside the clamor of gongs, the Yuan army deployed explosive projectiles. Gunpowder was nonetheless unknown in Japan; the black shells that exploded midair, releasing fire and smoke, amazed Japan's warriors and terrified its horses so that they could not fight. Under such conditions, the shogunate had no choice merely to retreat, while the Yuan soldiers went back to spend the nighttime on their ships.

Mōko shūrai ekotoba (Illustrated Story of the Mongol Invasions) is an account commissioned past the Kyūshū samurai Takezaki Suenaga, who fought in both of the battles. When the original (now held by the Purple Household Bureau) was plant in the late eighteenth century, information technology drew interest from daimyō and writers; many copies were made and around twoscore are known to be extant.

The Vanished Ships

The following morn, however, the Yuan ships were nowhere to be seen. This brought to an finish the beginning Mongol invasion, known as the Boxing of Bun'ei.

Many Japanese adults were taught in history classes that in both the Boxing of Bun'ei and the Battle of Kōan seven years afterward, the Yuan fleets were destroyed by heavy wind and rain. This was the kamikaze or "divine current of air." The conventionalities that a divine wind would accident to salvage the country when Japan faced crisis led to the tragic events involving kamikaze pilots in World War Two, only the idea dates back to the aftermath of the Mongol invasions.

Today's textbooks, however, accept significantly altered their presentation of the Boxing of Bun'ei. Consider the following case from a Yamakawa Shuppansha publication.

"The Yuan force, which had xxx,000 soldiers including troops from Goryeo, attacked Tsushima and Iki before coming ashore in northern Kyūshū at Hakata Bay. . . . Used to one-on-ane combat, the Japanese regular army struggled in the battle. Withal, the Yuan army also suffered considerable losses, also equally internal strife, earlier retreating. . . . In 1281, a huge army of 140,000 approached northern Kyūshū. Withal, while facing opposition to its landing at Hakata Bay, heavy wind and rain caused major casualties, and the Yuan forcefulness retreated again."

Here "internal strife" is given as a reason for the Mongol retreat in 1274. How do other textbooks compare? The respective textbook from Jikkyō Shuppan states that, "In the mixed army, morale was low among the Yuan and Goryeo soldiers, who suffered heavy losses in the unfamiliar boxing atmospheric condition before retreating."

Meanwhile a textbook from Tokyo Shoseki says that, "While the samurai struggled against the grouping tactics of the Yuan army, they too inflicted many casualties, forcing the Yuan retreat."

Thus, the adverse weather conditions that made the Yuan retreat have disappeared from these Japanese history textbooks. It is fascinating to annotation that while Yamakawa gives the reason for withdrawal as internal strife, Jikkyō offers low morale and the unfamiliarity of boxing atmospheric condition, while Tokyo Shoseki states that it is the efforts of the Japanese army. Each i is different. Only in the Shimizu Shoin textbook does it say that, "At that moment, in that location was heavy current of air and rain, and the invading ground forces apace retreated." Even here, though, there is no directly argument that the wind and rain was the decisive factor.

In other words, in that location is no by and large accepted explanation amongst historians as to why the Yuan army retreated. Kakehi Masahiro, a professor at Ferris University, offers an alternate theory. "For the Mongols, this was military reconnaissance, and so they remained where they had landed, and never had any intention of continuing to fight."

There are besides those scholars who still think that there was a draft. Hattori Hideo, a professor emeritus at Kyūshū University, writes in one of his books that there was heavy current of air and rain, merely the Yuan army did non retreat after only one day.

Based on materials including the diary of the Kyoto noble Fujiwara no Kanenaka, Hattori asserts that the Mongol army was in Japan for seven days earlier retreating due to a draft. He says that the typhoon is mentioned in Goryeo records. If this becomes the accepted theory, Japanese textbooks may once again attribute the Mongol retreat to stormy atmospheric condition.

Gratitude to the Gods

Afterward the 1274 Boxing of Bun'ei, the Yuan dynasty sent more emissaries to Japan enervating allegiance, merely the de facto leader of the shogunate Hōjō Tokimune had them all executed.

Kublai responded by sending an regular army of 140,000 to Japan in 1281. This included 30,000 from eastern Yuan, mainly from Goryeo, and 100,000 from southern China, including quondam Song troops. However, the Japanese side had learned from its previous experience, and was now well-versed in Yuan tactics. Its fortifications stretching for some 20 kilometers helped the shogunate army to preclude the huge Yuan ground forces from coming ashore.

The Japanese forces held on for effectually ii months until a large typhoon hit Kyūshū on August 23. While the shogunate army suffered considerable casualties, all of the Yuan ships sank and their soldiers were lost beneath the waves.

In the case of the 1281 Boxing of Kōan, scholars hold that a huge typhoon dealt a catastrophic blow to the Yuan ground forces. Both the court and the shogunate made prayers later on in thanks.

For example, Nijō Tameuji was dispatched by the imperial court to Ise Shrine, where he likewise visited a branch dedicated to a air current god inside the Inner Shrine. A rumor circulated that this god had sent groovy gusts to aid the Japanese against the Mongols. In 1293, the court raised the status of this shrine, naming it Kazahinomi-no-miya.

Other shrines also had their status raised by the courtroom, due to their supposed efficacy in the moment of crisis, including Hakozaki Hachimangū, Suwa Taisha, and Fuu Shrine. Equally Japan was thought to be a land of kami (native gods), the belief gradually spread that a kamikaze would protect the country in its time of need.

Kublai planned to make a further attempt to invade Japan, just Mongol forces made slow progress in campaigns in Vietnam, faced repeated rebellions in Mainland china and Southeast Asia, and were driven out of Java in a failed incursion. In the end, there was no opportunity to try once again.

A Weakened Shogunate

Despite its success in keeping the invaders at bay, the Mongol attacks weakened the Kamakura shogunate. At the fourth dimension, country gains funded rewards for boxing participants, and so with no new country the rewards paid by the shogunate were inadequate, especially equally the samurai had paid necessary battle expenses themselves. Many died in boxing, or were severely injured. Retainers under the direct authority of the shogunate were economically battered, and had to enhance money with their country equally collateral.

The Hōjō clan saw this as a hazard to take over important posts with its own people in the proper noun of emergency. However, this led to a breakdown in loyalty, contributing to the fall of the shogunate in 1333.

Ghost of Tsushima, an action-adventure game gear up at the time of the Mongol invasions, has raised interest in this menstruum in Japanese history.
