the Failed Mongolian Invasions of Japan

The First Mongol Invasion of Japan – 1274 — The Second Mongol Invasion of Japan – 1281

Divine Intervention can be a bitch...

Divine Wind = *$%#* slap from nature

Both Japan and China have a long-intricate backstory, each with a unique and rich cultural history that spans thousands of years. Today, it seems like practically everything in the world is manufactured from one of these two economic powerhouses, but long before they began exporting anime, video games, and John Woo action movies, these two nations were all but isolated from the rest of civilization, and for the most part, each other. Well, that is until this one time…

You see, during the 1200’s these two nations were under the rule of some of history’s most badass military forces: The Mongol Warriors of China’s Yuan Dynasty and the elite warrior caste of feudal Japan: the Samurai! It was at the later half of the Thirteenth Century when these two legendary warriors finally came into conflict with one another. Regardless of the outcome, it was sure to be a spectacular showdown that would echo through the halls of their ancestors, like the taunts of opposing football teams echoing through the locker rooms.

The Mongols Take China

So the Mongols were this group of hardcore warriors who first came together with the sole purpose of conquering the world (or at least Asia). They were a rambunctious horde of horse-back riding, arrow-shooting, felons who were first brought together, under the united banner of the Mongolian tribes, by a larger-than-life butt-kicking fiend known as: Genghis


*Genghis* Khan (not to be confused with the Trek villain)

Between siring an astronomical number of heirs, Genghis Khan (read all about him here) conquered practically everything in sight. Whole villages would bow down before him, just because they’d heard rumors of the unpleasant alternative. He was even quoted as saying,“I am the scourge of God. Had you not created Great Sins, God would not have sent a punishment like ME upon you!” Modesty was not exactly his strong-suite. With an army of one-hundred-thousand, Genghis Khan took on the world, and won.

The empire he left behind eventually stretched from the Eastern Coast of Asia to Germany! That’s larger than any single country today! This Mongolian legacy was inherited down the line by Kublai Khan, the grandson of Genghis, who established what is known as the Yuan Dynasty of China. He also once even met a guy named Marco Polo. Kublai Khan also decided to expand the Mongolian Empire, like his grandpa Genghis. The Mongols were basically the only ones in history to lead a successful assault on Russia in the middle of winter! So naturally they figured those islands off the coast of Korea shouldn’t be too much trouble, right?

Meanwhile, in Japan…

Around this same time, Feudal Japan was an interesting place to say the least. The only way I can think to describe it is a mix between the Wild West and a classic shogun movie. For much of its history, Japan was at war, with itself. Originally established as a government that closely resembled the Chinese, the Japanese soon began to culturally differentiate themselves from their neighbors across the bay, during the Heian period.

In 645 CE, a series of tax / land reformations were issued by the Japanese Emperor, a disastrous failure known as the Taika Reforms which inevitably backfired, and directly led to the land owners and farmers gaining more political power than the actual government. This gave rise to the Fujiwara Clan headed by Nakatomi no Kamatari from the capitol of Kyoto. The Fujiwara family ruled Japan until the 11th Century when public order evaporated like an ice cube in Death Valley and the islands soon fell into chaos.

Enter: the Samurai

The Samurai were armor-wearing martial artists with the single-coolest weapon ever created: The Katana, a super cool sword with a curved blade and elongated hilt. The lone, often nomadic, Samurai warriors answered to no one… well, except for the guy with the biggest check book. Wealthy landowners across Japan would hire armies of these Katana-sporting mercenaries to protect their property.

81px-Busido_kal.svgSamurai were said to have lived by a code of honor known as Bushido, ‘The Way of the Warrior’ which was similar to that of the Knight’s code of Chivalry, with a Zen Buddhist twist. The Seven Virtues of Bushido are as follows: Rectitude, Courage, Benevolence, Respect, Honesty, Honour, and Loyalty. Above all else, their goal in life was to die an honorable death, a trait shared by their Nordic counterparts, the Vikings.

The two most powerful clans of Japan at the time: the Taira and Minamoto clans, constantly vied for supremacy, often pitting their greatest warriors against one another in single-combat death-battles. Eventually, in 1192, Minamoto Yoritomo emerged the victor. Minamoto established a new order: martial law enforced by the Shogun, military commanders of the Samurai forces. Together, the Shogun and Samurai would maintain relative peace for the next 700 years…

Kublai Khan picks a fight

Samurai_vs_Mongol_by_jugodenaranjoThe year was 1266. While pillaging his way across the continent, Kublai Khan paused for a moment to insult the Japanese Emperor (Kameyama) before asking him to send a donation. In his letter, Kublai Khan referred to the Emperor Kameyama as “the ruler of a small country” and advised him to pay tribute, or else. The 1200’s equivalent of a whiny internet troll demanding attention in the comments section of a You Tube video.

The Mongolian emissaries returned with no response (although I’m willing to bet the messengers simply didn’t want to repeat the real response to their kill-crazy despot’s face). Over the next six years, Khan sent *Five* separate notifications to the shores of Japan, and each time the Mongolian messengers were sent packing with nothing more than “the finger” in response to Kublai’s request.

Finally, after losing his patience, Kublai Khan said “That’s it!” and in 1272 he commissioned the construction of about 600 sea-faring attack-ships, drafted an army of 40,000 Mongols, Chinese, and Koreans over the next two years and prepared his armies for a full-scale invasion of Japan!

The Mongolians had an armada of ships that would embarrass the Greeks during the Siege of Troy. They set sail for the East, and got all pumped, cranking up the death metal tunes en route. On their way across the sea to Japan’s mainland from Korea, the Yuan warriors stopped by a few smaller islands along the coast and kicked their butts too, just because. These stab-happy Mongolian warlords were all walk and no talk, that’s just how they rolled. These guys meant business.

BTASThe Samurai on the other hand were smooth operators: calm and efficient in everything from trimming a Bonsai tree to committing suicide when they failed. This ragtag group of honorable mercs knew they were hopelessly outnumbered, but 10,000 samurai answered the call anyway and geared up for the coming battle. Assembling along the shore, they wore elaborate armor and masks that were evocative of demons, striking fear into the hearts of their enemies – like a medieval Japanese Batman, and just like the Dark Knight, they were not to be trifled with!

Round One: FIGHT!

800px-Mōko_Shūrai_Ekotoba_2On November 18th, 1274: the Khan’s armada was in sight of Hakata Bay, on the island of Kyushu (near Fukuoka, which sounds like a funny insult).

Here’s how I imagine this went down:

When the Mongolian boats appear, a lone Samurai warrior walks out onto the beach. He bows before the intimidating might of the mighty Khan’s forces, barely acknowledging the approaching war drums. This single samurai warrior shouts above the roar of the tide, announcing his full name, title, and lineage, as is his time-honored custom. The brave Samurai is preparing for one-on-one combat, a tradition passed down through the ages by his ancestors. However, halfway through listing his heritage his face becomes a pin-cushion for a volley of arrows…

"Come at me Bro!"

“Come at me Bro!”

Next, another samurai appears out of the bamboo woods, swearing to avenge his fallen master and openly challenging the entirety of the Mongolian invasion force, right before he too is obliterated. This probably went on a few more times until the Japanese came to the realization that the Mongols approached combat a little differently. Their form of combat would have been akin to an ant attempting to fight off a magnifying glass.


This brutal onslaught would have decimated the first wave of samurai if it weren’t for last-minute reinforcements which allowed them to retreat and lick their wounds. The remaining samurai said their prayers, kissed their families goodbye and prepared for a futile last stand against this unstoppable legion. However, fate had different plans in store.

That very night prior to the armada’s landfall, a torrential downpour came over the bay. The soldiers of the Great Yuan Fleet worried the incoming winds would crash their wooden ships against the rocks along the coast, so the commanders decided to set sail into the ocean and sit out the storm. Unfortunately, for Khan’s men, the entire armada was welcomed by a ginormous swirling monstrosity, known today as a TYPHOON!

"Um... guys?!"


48 hours after sailing into the oncoming storm of doom, the Mongolian Fleet was completely and totally annihilated after taking a brutal smack down from Mother Nature herself! One-Third of their ships lay at the bottom of the bay. This devastating defeat at the vicious hands of hurricane-force winds forced the Mongols to retreat back to China after just a single day of combat!

A Mongolian Cluster...

A Mongolian Cluster #%&!

The unfortunate news of the fleet’s utter destruction soon reached the Yuan capital at Dadu (Beijing). Upon hearing the reports of their losses, Kublai Khan didn’t seem so much phased by the incalculable loss of life as he was preoccupied with the fact that his plans for world domination had been foiled by a freak storm. However, he seemed to take the news reasonably well considering he’d just lost a large-scale game of Battleship against himself.  After silently brooding in contemplation, Khan dispatched a delegation of six Chinese diplomats to Japan, giving the Kamakura Emperor a choice: bow down before his might (in person), or be destroyed.

The Japanese response came in the form of six decapitated Chinese diplomats…

A Seven Year Interlude

You would think that having just suffered a PR nightmare, Kublai Khan would keep his cool and not do anything brash in response to this hollow provocation. Instead the Mongolian Emperor decided to invest all his resources into crushing his new sworn enemy by any means necessary. Another, even larger, fleet was commissioned with the sole purpose of crushing the Japanese resistance.

Over the next seven years the Mongolian forces regrouped, rebuilt, and rearmed a brand new and improved armada under a newly created government department: The Ministry for Conquering Japan (seriously!). This newly minted division of Mongolian bureaucrats drafted a two-pronged, fail-proof, plan of attack. Pleased with this, Kublai Khan put his stamp of approval on it.

This time however the Samurai had also been given a *Seven Year* window of prep time. A 25 mile long, 15 foot high, defensive wall was built around the perimeter of Hakata Bay and there were now 40,000 samurai awaiting their dreaded enemy from the west. This time they were ready to kick some Mongolian beards in. This time it was personal.


The Mongolian Yuan army was also eagerly anticipating a quick end to this cursed campaign. There would indeed be a quick and decisive end, just not the way they had in mind. A whopping 140,000 Mongol warriors aboard 900 ships set sail in two separate fleets from Southern China and Korea.

Round 2…

The Korean fleet arrived at Hakata Bay on June 23, 1281. This time, they were surprised to find a militarized fortification in their path. The Chinese fleet was running late, so they decided to wait for reinforcements. The Great(er) Armada never arrived… (more on that later)

Over the next 50 days, while the Mongols awaited backup, a bunch of sneaky Samurai silently rowed out into the bay, under the cover of darkness. These Samurai black-ops would raid their ships, assassinate their soldiers, and then set their boats on fire for good measure. After committing naval arson, they quietly ninja-ed out and rowed back to shore before the remaining Mongolian commanders smelled smoke the next morning.

Meanwhile, out to sea… an even larger convoy approached on the 12th of August, 1281: 3,500 ships manned by more than 100,000 Mongolian soldiers! While the brave samurai sharpened their steel, the Shinto monks desperately prayed against all odds for a miracle. Funny thing is, their prayers were answered! Three days later, this unprecedented Mongolian armada had Japan in its sights when they all started to hear the cracking of thunder over the bay. This is probably what they saw in the distance:


Uhh… is that what I think it is?

Ahh Hell no!!

Ahh Hell no!!

This even bigger, stronger attack force was met with something far deadlier: A SECOND TYPHOON!

This wasn’t just any kind of storm, this was the kind of storm that only occurred once every three hundred years or so and it just so happened to show up and rain on this Mongolian parade… once again.

Relentless winds, torrential rain, and towering waves battered the ships into one another until they were nothing but splinters. The few Mongols unlucky enough to wash ashore were then greeted by Japanese steel. This swirling vortex of doom completely annihilated any potential chance the Mongols ever had of conquering Japan… a second time in a row! Only a handful of beat-up Mongols made it back to China alive.

What are the chances?!

Most of what we know about these invasions comes from a scroll scribed by a samurai by the name of Takezaki Suenaga, who survived both campaigns, barely. According to the Japanese, who had prayed to the Shinto God of War (Hachiman) for help, the gods had indeed showed up to aide them with Kamikaze, or “The Divine Winds”.

Unfortunately for the Kamakura bakufu (the Japanese government of the time), their treasury had already run dry between paying the veterans of the first invasion, and the Shinto priests who claimed responsibility for their miraculous victory, leaving the actual samurai soldiers who fought and bled for their emperor with nothing.

This actually led to a 15 year civil war in 1318 when Go-Daigo seized power and the disgruntled samurai took his side, but that’s another story.

….Round 3?

Following the Second (FAILED) Invasion of Japan, the Mongols had once again suffered monumental losses, in both sheer casualties and incomprehensible expenses. Not only that, but the notion of their perceived invincibility had been forever stained. All of these factors would eventually lead to the inevitable decline of the Mongolian rule.

Kublai Khan could care less, even after this embarrassing defeat, he was completely and utterly determined to mount a *THIRD* invasion, regardless of the horrendous economic pitfall that they’d already fallen into. He began to plan for an even bigger assault! Go big or go home I guess?

However, as fate would have it, the Khan died before he could go through with it. His successors, who knew when to take a hint, unanimously decided to cancel the whole operation.

      Thank you so much for your reply Jc!

      You are technically correct, I went back and did a little editing, hoping to clear that up (this is one of my earlier articles). While the Mongols had conquered and absorbed China, not all Mongols were Chinese. However, it’s worth noting that during this period, Kublai Khan was the Emperor of China’s Yuan Dynasty.
