Japanese Sword Names Explained

Do You Know What a Japanese Sword Actually Is?

When people hear about Japanese swords, the immediate images that often come to mind are those of iconic figures like samurai warriors, ninjas, or even playful references like “Samurai Jack” or the mobile game “Fruit Ninja.” These cultural touchstones often paint a picture of swords as instruments of martial prowess or popular entertainment. However, Japanese swords encompass a much broader and deeper cultural significance. Beyond their association with warriors, these swords are embodiments of centuries-old craftsmanship, steeped in traditions that emphasize not only functionality in combat but also artistic expression and spiritual symbolism. These blades served diverse roles in Japanese society, wielded by samurai as symbols of honor and duty, but also cherished by aristocrats, merchants, and even religious figures. Today, Japanese swords are revered globally for their beauty, historical significance, and the enduring craftsmanship that continues to captivate admirers worldwide. In this article, you’ll find our more info about japanese sword names and their rich history.

Before the Beginning

Swords in Japan have quite the history starting with straight swords (chokutō) brought from Asia during the Kofun period (3rd to 7th century). These swords were worn with the blade down on the left hip, like a fashionable ancient belt accessory! Fast forward to the Heian period (794-1185), and curved swords (wantō) became all the rage, especially after some northern conquests. Then, during the chaotic clan rivalries of the late Heian period, super-long curved swords (tachi) came into play. That’s when things got serious like, “my sword is longer than your sword” serious. And thus, the era of Japanese swords began, blending craftsmanship, style, and a lot of historical drama into every swing.

The Beginning of an Era of Japanese Sword Names

Picture this: back in the day, there were “old swords” (kotō), “new swords” (shintō), and even “new, new swords” (shinshintō). It sounds like they were just trying to keep up with sword trends, right? Then came the Battle of Sekigahara in 1600, where the line between “old” and “new” swords was drawn, kind of like a sword-themed fashion show finale.

Before Tokugawa Shogunate strutted onto the scene, it was all about the majestic tachi swords – long, heavy, and worn edge-down from the waist. But hold up! Along came the uchigatana, or as you probably know it by its iconic name, “katana,” which is shorter, lighter, and way more versatile. It was the perfect accessory for a samurai on the go, worn edge-up in the sash like a stylish sidekick.

And hey, next time you see a Japanese sword in a photo, check out how it’s displayed: some blades are up, some are down. It’s not just sword photography posing. It’s a historical homage to how these bad boys were rocked back in the day.

Artistry in Japanese Swordcraft

Blade Artistry

Each sword is a masterpiece shaped by regional styles like Yamashiro, Bizen, and Sōshū, each with unique curvature and forging techniques. The Sugata, or blade shape, isn’t just about looks. It’s optimized for cutting and balance, making these swords lethal and practical. What sets them apart is the Hamon, that mesmerizing wavy line along the blade edge. It’s not just for show. It’s created by heating and cooling techniques that toughen the edge while keeping the spine flexible. Imagine the skill it takes to polish a blade to reveal that perfect hamon shimmer! From the razor-sharp tip to the carefully shaped tang (Nakago) that fits snugly into the handle (tsuka), every detail speaks volumes about the swordsmith’s art.

Koshirae (Sword Mountings) Aesthetics

Koshirae, the art of Japanese sword mountings, is a realm where craftsmanship and symbolism converge with meticulous precision. Each element, whether it’s the menuki (grip ornaments), tsuba (handguard), Fuchi and Kashira (handle fittings), or the saya (scabbard) lacquer – serves both functional and aesthetic purposes. The menuki aren’t mere decorations: they provide balance and grip, essential for wielding the sword with precision and control. Tsuba, often adorned with intricate designs, not only protects the hand but also signifies the status and taste of the sword’s owner. Fuchi and Kashira are meticulously fitted to the handle, ensuring durability and enhancing the sword’s overall balance. The Saya, crafted with layers of lacquer, not only protects the blade but also showcases the artisan’s skill in achieving a flawless finish. Each component of Koshirae is crafted with utmost care, reflecting centuries of tradition and the artistic sensibilities of Japanese swordsmiths. 

Famous Japanese Swordsmiths

Masamune

Masamune is often regarded as Japan’s greatest swordsmith, known for his exceptional craftsmanship during the Kamakura period (1185-1333). His swords are revered for their superior quality, exquisite beauty, and unparalleled sharpness. Masamune’s blades are characterized by their graceful curves, flawless forging techniques, and the ability to retain a sharp edge while remaining resilient. Legend has it that his swords possessed a gentle and benevolent spirit, known as “Masamune’s soul” or “Masamune’s blessing,” which brought good fortune to their wielders.

Samurai clans favored Masamune’s swords and even bestowed them as gifts between lords and rulers. Many of his works are considered national treasures of Japan, held in high esteem for their practicality in battle and artistic and spiritual significance.

Muramasa

Muramasa, believed to have lived during the Muromachi period (1336-1573), was known for his unmatched skill in creating blades of exceptional sharpness and cutting ability. However, his swords were also said to possess a cursed or bloodthirsty spirit, often called “Muramasa’s curse” or “Muramasa’s evil edge.”

According to folklore, Muramasa’s blades had a violent propensity and were believed to drive their wielders into a frenzy or bloodlust during battle. Samurai were said to avoid Muramasa swords, fearing their unpredictable nature and the potential for tragedy. Despite this reputation, Muramasa’s craftsmanship was highly regarded, and his swords are noted for their distinctive hamon (temper line) patterns and cutting prowess.

Both Masamune and Muramasa remain iconic figures in Japanese sword history, representing contrasting styles and the rich cultural heritage surrounding swordsmithing in Japan. Their legacy continues to captivate enthusiasts and collectors worldwide, with their swords serving as tangible connections to Japan’s martial past and artistic traditions.

Legendary Swords in Japanese Mythology

Kusanagi-no-Tsurugi

Kusanagi-no-Tsurugi, known as the “Grass-Cutting Sword,” is one of Japan’s Three Imperial Regalia. According to myth, the storm god Susanoo discovered this divine sword inside the tail of the fearsome eight-headed serpent, Yamata no Orochi. Banished from the heavens for his mischievous behavior, Susanoo encountered Orochi terrorizing the land. To appease the serpent’s hunger, Susanoo proposed a challenge: if Orochi could consume seven barrels of sake (rice wine) from Susanoo’s daughters, then he would allow it to do so. As Orochi prepared to consume the eighth maiden, Susanoo intervened. During the battle, he found Kusanagi-no-Tsurugi within one of Orochi’s tails. Impressed by the sword’s beauty and power, Susanoo presented it to his sister, the sun goddess Amaterasu, as a reconciliation gift. Kusanagi-no-Tsurugi became one of the Three Sacred Treasures of Japan, symbolizing the imperial family’s divine right to rule.

Totsuka no Tsurugi, another of Susanoo’s swords, was discovered within Orochi’s tails, highlighting its association with heroic deeds and mythical battles.
