a warrior named Jinmu, who, perhaps during Christ’s lifetime, sailed from the Kyushu Islands to Honshu, the central and largest of the four main islands of Japan. Jinmu would become the first emperor of Japan, after defeating the hostile tribes inhabiting Honshu’s Yamato Province.
Legend tells us that this brave man was endowed with “spirit from the gods.” But even the gods couldn’t bring stability to Japan: constant struggles for power and control of land would bring down emperor after emperor.
During the period extending through the ninth century of the Common Era, weapon making in Japan was based mostly on designs created by swordsmiths of Chinese origin and, to a lesser degree, craftsmen from Korea and Japan. The swords they created would likely have been of the Chokuto, straight-edge type, modeled after the one-handed jien (“sword,” in Chinese) or ken (Japanese pronunciation), with straight, double-sided blades. In 645 CE, the Taika Reform established the supremacy of the imperial family, making the emperor the absolute ruler of all Japan. In 710, the capital of Japan was established in the Yamato Province at Nara, marking the beginning of the Nara period (710–784). Japanese nationalism slowly gathered momentum, setting the stage for a great leap in Japanese sword design.
According to legend, a swordsmith named Amakuni (circa 700 CE) observed scores of samurai he had outfitted returning from battle with broken blades. Saddened by the flaws in his work, he sought to produce a superior tool that would return unscathed from the heavy use typical during battle. Amakuni and his son prayed for spiritual guidance, disappeared into his shop, and emerged about a month later with superior ore and tempering methods that resulted in what would become known as the first “samurai swords.” But new materials and methods were not Amakuni’s only contribution to the development of the samurai sword: purportedly, he was the first to create the superior one-sided, curved tachi blade.
Parallel to the refinement of sword-making skills, a myriad of combat techniques proliferated from experience with the sword on the battlefield, as well as in individual duels between samurai who employed the grand weapon. Its arc shape not only gave it martial prowess in terms of sword strength, but also enabled its user to draw the weapon much more efficiently than the straight-edged type. With it, samurai could draw and fight at a moment’s notice, unlike those armed with the older, long and clumsy straight blades. Amakuni’s modification of the samurai sword was perfectly timed: With Japan’s growing nationalism came the need for augmentation of samurai sword production, in order to meet the needs of the national army which defended the emperor against potential usurpers.
But this new blade was more than just a weapon—it was the hallmark of a growing warrior culture that would influence every factor of life in Japan for hundreds of years. Who could have imagined that this single accomplishment by one Japanese swordsmith and his son would be instrumental in elevating the perception of Japan in neighboring communities such as China and Korea and, most importantly, in the minds of the Japanese people, who had formerly perceived themselves as inferior to the Chinese across the sea?
KOTO OR OLD SWORD PERIOD
The samurai sword would only become more important during what is known as its Koto period (900–1530). Civil unrest was fostered by the extravagant habits of the Fujiwara clan, whose daughters married their way onto the throne of the imperial family. A period of lawlessness marked the end of their avaricious one-hundred-year reign, as their greed (rather than devotion to duty, the hallmark of more successful Japanese rulers) enabled the Minamoto and Taira samurai clans to usurp Fujiwara power and reestablish order. It was during this time, about 200 years after Amakuni manufactured his samurai sword, that Yasutsuna, a swordsmith in Hoki Province, would “perfect” the sword. He utilized painstakingly chosen iron sand and ore, incorporating high-heat tempering techniques that became the staple method of producing samurai swords.
Another important aspect of sword making during this period was the Five Schools, organized groups of samurai sword craftsmen that filled the constantly changing needs of the government, as power in Japan changed hands and the capital moved around the country. The Koto period saw the highest volume of samurai sword production in Japanese history, and the swordsmiths of the Five Schools, each based in its own province—Yamashiro, Sagami, Yamato, Bizen, and Mino—produced 80 percent of them, some of which were purportedly the finest samurai swords ever crafted.
Yamashiro, the earliest of the Five Schools, established itself in Yamashiro Province, in the capital at Heian (present day Kyoto), and became the local weapon supplier for the imperial government while its leadership remained there. As with the other schools of samurai sword manufacture, an abundance of high-quality iron ore, iron sand, and nearby water was an important deciding factor in the location of this school.
In 1192, the Minamoto clan took full control of the government, and the capital was moved to Kamakura in Sagami Province. The Sagami, or Shoshu, School established itself in response to this move, and the Yamato, Bizen, and Mino Schools came about to meet the demands of samurai in other regions.
Nationwide, a new samurai class was born when the Minamotos became the first to establish a feudal system of government, or shogunate, with a military style of leadership. This differed from despotic rule by a single emperor; the shogunate was a hierarchy in which regional feudal lords called daimyo answered to the shogun (military leader), and the samurai, highly trained and loyal warriors, served the interests of the daimyos.
A samurai went to exhaustive lengths to protect his master’s honor, as well as his own, while at all times thinking of the “spirit of Japan,” which made up the fabric of his being. As a consequence of his belief that his service to his nation was tantamount to his duty to his daimyo, he outwardly manifested unceasing respect, courtesy, and justice in the presence of the people of his nation. The samurai took their role as protector so seriously that when they considered themselves to have been shamed or to have failed at some task, they committed ritual suicide (seppuku).
Bitter infighting within the Minamoto family resulted in the death of Japan’s first shogun, Minamoto Yoritomo. Yoritomo’s widow, Hojo Masako, enabled the Hojo family to rise to power in the Kamakura-based leadership. Then in 1274 and 1281, the Mongols attacked Japan, creating a national emergency. This crisis prompted the Sagami School—whose craftsmanship was a blend of the Yamato, Yamashiro, and Bizen manufacturing techniques—to pursue rigorous samurai sword production, to defend the nation by serving the needs of the Kamakura government, which was located in their province. Fortuitously, the Mongols would be thwarted by a combination of the samurai and what was perceived to be help from the spirits—typhoons that struck to the advantage of the Japanese during each invasion, leading them to victory. On the domestic front, the shogun system had begun to fail. The quasi-military leadership, including officials who were more like civil servants than strong warriors, was weakened by the expense of defending the country from the Mongols. This created an opportunity for Godaigo, a man of the imperial line, to enthrone himself as emperor and attempt to abandon the shogunate system.
Godaigo seized power with the support of a clan of samurai warriors called the Ashikaga, but they later betrayed him by reinstalling the shogunate and forming their own government in Kyoto. Emperor Godaigo fled to the Hill of Yoshino near Nara, from which he attempted to rule the nation. For the next forty-five years, there would be two imperial courts, resulting in a lack of centralized control that encouraged lawlessness. Land disputes and power struggles between feudal lords led the Japanese into a bleak era of warfare known as the Sengoku period (1467–1574). During this period of chaos and discord, a broader spectrum of the Japanese population came to use samurai swords, and the demand for them continued to be great. The upheaval of these dangerous times and the increased availability of the samurai sword gave rise to what would become a variety of different “ways” or ideologies about how to employ the weapon. And as the tactics and techniques of warfare evolved, the samurai sword’s characteristics were modified in order to address the particular circumstances of the swordsmen.
