The Curse of the Samurai Muramasa Blades

(Read the article on one page)

In Nitobe Inazo’s 1899 work exploring the way of the samurai, Bushido, the Soul of Japan , the sword is dubbed as the ‘Soul of the Samurai’. As swords were so highly revered, the swordsmith’s work became an immensely important task. In Chapter XIII of Nitobe’s work, the writer speaks about the swordsmiths as follows: “The swordsmith was not a mere artisan but an inspired artist and his workshop a sanctuary. Daily he commenced his craft with prayer and purification, or, as the phrase was, "he committed his soul and spirit into the forging and tempering of the steel." Every swing of the sledge, every plunge into water, every friction on the grindstone, was a religious act of no slight import.” Some of Japan’s ancient swordsmiths became as famous as the samurai themselves. One of the most well-known Japanese swordsmiths was Muramasa Sengo, second only to Masamune Gorō.

Muramasa Sengo was a swordsmith who lived during the Muramachi period (between the 14 th and 16 th centuries A.D.). In some legends, Muramasa is portrayed as a disciple of Masamune, though this is historically impossible, as Masamune lived several centuries before his alleged student. Muramasa has been described as completely mad and prone to bouts of violence. It was therefore believed that these destructive qualities were passed by the master swordsmith into the blades he forged. The blades would then ‘possess’ their wielders, turning them into insane and deadly warriors, just like Muramasa himself.

Muramasa’s blades are often contrasted with those of Masamune. In one legend, Muramasa, who is said to be a disciple of Masamune, challenges his master to a sword-making competition. This was to determine who the greatest swordsmith in the country was. After both swordsmiths had completed their blades, they prepared to test their weapons. The contest was as such: The blade was to be suspended in a stream with the sharp edge facing the current. Muramasa’s blade cut everything that passed it, including the fish, leaves and even the air. By contrast, Masamune’s blade failed to cut anything. In spite of this, Masamune was declared the winner, as Muramasa’s blade was blood thirsty and cut indiscriminately, whilst Masamune’s did not cut and kill needlessly.

Despite the bad reputation surrounding the blades Murasama forged, they were undeniably of high quality, and were popular in Japan. This is evident in the fact that his school of sword-making was passed down to his students and continued for the next two centuries. It was during the reign of Togugawa Ieyasu, the first shogun of the Edo period, that Muramasa’s blades fell out of favour. The shogun’s father, Matsudaira Hirotada, and grandfather, Matsudaira Kiyoyasu, were both murdered by their retainers who were wielding Muramasa blades. The shogun himself was also cut by a (supposed) Muramasa blade whilst inspecting the yari (a Japanese type of spear) of one of his generals.

These coincidences gave rise to the legend that Muramasa’s blades had the power to kill members of the Tokugawa family. Consequently, the shogun decided to ban ownership of the Muramasa blades. Many blades were melted down, though some were hidden away. The ban was taken seriously by the shogun, and those caught keeping Muramasa blades were severely punished. The most notable case was that of Takanak Ume, the Magistrate of Nagasaki. In 1634, the magistrate was discovered to have hoarded 24 Muramasa blades, and thus was ordered to commit seppuku (ritual suicide by disembowelment). Despite such harsh punishments, there were those who continued to keep Muramasa blades, and even had the markings on these blades changed so as to avoid detection from the authorities. In addition, numerous forgeries have been made over the year, thus making it quite difficult today for authentic Muramasa blades to be identified.

As a symbol of the superior sword-making skills of the Japanese, Muramasa’s blades have also been incorporated into today’s popular culture. References to this icon can be found in various media ranging from video games to Japanese anime and even in the Marvel Universe.

The question of whether a god exists is heating up in the 21st century. According to a Pew survey, the percent of Americans having no religious affiliation reached 23 percent in 2014. Among such “nones,” 33 percent said that they do not believe in God – an 11 percent increase since only 2007.

Ancient Technology

Every time ancient Greece is mentioned most people automatically think of democracy, the Olympic Games, mythology and philosophy. It seems that not many are aware of how advanced the ancient Greeks were on a technological level as well and the Antikythera Mechanism, known as the world’s first analog computer, is the brightest example of all.

Few of the modern visitors to Teotihuacan are aware of the vast and mysterious underworld of caves and man-made tunnels that extends under much of the ancient site and for miles around. The existence of these tunnels has been known for centuries, but not even the most recent research has been able to solve the mystery of their origin and purpose. Very much like at Giza, in Egypt, these tunnels are rumored to connect all the main pyramids by means of underground passageways, and perhaps even lead to the records of a lost civilization.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
