The Greatest Samurai Battle

The clash was like a tale straight out of a classic Western movie. The young fighter had come to town seeking to make a name for himself by taking down the feared veteran. The two men would face off at high noon. Instead of carrying pistols, however, they wielded swords. For the year was 1612, and they were both members of Japan’s great warrior class, the samurai.  

The challenger, Miyamoto Musashi, seemed to have come out of nowhere. About age 29, he traveled alone, with few possessions. Little about him was known other than his reputation as a swordsman. 

In contrast, Sasaki Kojiro, about 37, was a sword-fighting icon. He was a respected martial arts instructor for a powerful clan on the Japanese island of Kyushu (see map, below). Kojiro’s deadly skill with a three-foot-long steel sword had earned him fame as the Demon of the Western Provinces. 

The fight between the two men that day lasted only a few minutes. But the match would become a legend—perhaps the most famous samurai battle of all time.

Today, Japan is a stable democracy. But for many centuries, it was torn by constant warfare between rival warlords called daimyo (die-myo), who commanded their own armed forces. The warriors in those armies became known as “those who serve,” or samurai.

Samurai were fierce fighters who excelled in the martial arts, including swordsmanship, horse riding, and archery. They held an elite status in society, following a code of conduct called bushido (boo-she-doh), or “the way of the warrior.” 

“Samurai were supposed to be sincere, work hard, and have a sense of obligation to their [daimyo’s] family and domain,” says historian Michael Wert of Marquette University in Wisconsin. 

In 1603, Japan underwent a major change. That year, a powerful shogun, or military governor, named Tokugawa Ieyasu took control of most of the country. Tokugawa stopped the unending conflict. For about 260 years, Japan didn’t experience a single large-scale war.

The role of the samurai changed too. Without wars to fight, many of them moved into towns, where they helped run local governments. Yet there was another problem. Japan’s government kept the peace in part by cracking down on the daimyo—sometimes even by seizing their lands. Whenever this happened, or a daimyo died, samurai were without a home. This left “masterless” samurai called ronin to wander Japan’s mountain paths, looking for food and work—and often getting into fights.

Some had a more specific ambition: seeking out contests of skill to establish themselves as great swordsmen. One of those ronin was the young Miyamoto Musashi.

Some had a more specific ambition. They searched for contests of skill to establish themselves as great swordsmen. One of those ronin was the young Miyamoto Musashi.

Born around 1584, Musashi displayed great skill with the sword at a young age. His first victory is said to have been at age 13. By age 16, Musashi was wandering like other ronin and building a reputation. “His self-discipline and training during this time must have been rigorous and intense,” writes biographer William Scott Wilson.

In his mid-20s, Musashi settled for a time in the capital, Edo (today Tokyo). By then, he had won almost 60 contests without a defeat. But he was restless and seeking new challenges. So in 1612, he set his sights on his most formidable opponent yet: Sasaki Kojiro.

The two samurai agreed to do battle on a tiny island off the coast of Kyushu. Legend has it that Musashi made it a duel of wits—rattling Kojiro by keeping him waiting. By this account, Musashi slept in on the day of the contest and took his time getting to the island. On the way, he carved a wooden sword from an oar—one slightly larger than Kojiro’s famous three-foot steel weapon. 

Kojiro had arrived promptly—but by the time Musashi appeared, hours had passed. Furious now, Kojiro rushed forward with his sword. 

The men’s swords pierced the air. Kojiro’s sword sliced through the middle of Musashi’s headband, striking cloth but not skin. Musashi’s wooden sword caught Kojiro smack on the forehead, sending him to the ground. Flat on his back, Kojiro slashed at Musashi’s thigh, a blow the younger man dodged. Then Musashi brought his sword down with all his force, ending the fight—and Kojiro’s life.

By this version of the story, Musashi slept late on the day of the contest. Then he took his time getting to the island. On the way, he carved a wooden sword from an oar. It was slightly larger than Kojiro’s famous three-foot steel weapon.

This ended the fight—and Kojiro’s life.

The match was a turning point for Musashi. He was famous now. Wherever he went, swordsmen and daimyo sought his instruction.

At the same time, he was a changed man, biographer Wilson says. “Musashi felt a kind of remorse” at killing the respected Kojiro. “He never fought another duel to the death.” More and more, he devoted himself to other samurai disciplines, including painting, garden design, and meditation. 

In old age, he settled on Kyushu. Knowing his time was short, he moved alone into a cave, where he painted and summed up his beliefs in The Book of Five Rings. A book on swordsmanship, it’s also about “how to approach life,” Wilson says. Influenced by the teachings of Zen Buddhism, Musashi wrote that success requires a strong character, discipline, and a clear and open mind.

Musashi died in 1645, at about age 62. As a priest offered a prayer to his spirit, the story goes, a single crack of thunder rang from a clear sky.

In the mid-19th century, more profound changes in Japan would bring the samurai era to an end. For centuries, the country’s leaders had kept its borders closed and its people isolated from most of the world. Then in 1853, Commodore Matthew Perry of the U.S. Navy sailed to Japan. He forged a trade agreement between the two countries, opening the door to Western influences.

He forged a trade agreement between the two countries. That opened the door to Western influences.

In 1868, years of poverty and unrest in Japan sparked a revolution that overthrew the country’s government. No longer would shoguns rule the land. The samurai class was officially abolished. 

“Japanese people wanted to be modern now,” says Wilson. “The samurai were a step backward.”

But nearly a century later, after Japan’s defeat in World War II (1939-1945), its people began looking back fondly. Japanese filmmakers, inspired by American Western movies, dramatized tales of the samurai in new ways. Musashi, for one, has reached a kind of superhero status in Japanese pop culture. He is the subject of countless movies, books, and even video games. His text, The Book of Five Rings, is still read widely today. 

This doesn’t surprise Wilson, who says samurai stories have long been “drummed into the Japanese mind.” You can also see samurai influences in popular anime (cartoons) and manga (comics). “They’re full of things like self-sacrifice and loyalty,” he says. It’s all part of that legendary warrior code of the samurai.
