The Embodiment of the Bushido Spirit: Discover the Past and Present of the Japanese Sword

Historically recognized as one of the world’s three greatest cold weapons*, the Japanese sword has garnered fame for its razor-sharp lethality and refined craftsmanship, embodying the essence of Eastern aesthetics. These qualities make it highly sought after by collectors. Some legendary swords, exquisite designs, graceful curves, and meticulous detailing, are still regarded as “National Treasures” in Japan. The duality of its nature—both a violent weapon and a work of art—lends the Japanese sword an unparalleled allure among cold weapons.

The History of the Japanese Sword

The history of the Japanese sword can be traced back to the mid-Heian period. During this time, ancient Chinese and Korean swords were introduced to Japan, producing numerous imitations. These early swords, differing from the commonly seen curved blades like the tachi, were mostly straight-edged and held more symbolic than practical value, often crafted to reward meritorious subjects by the emperor and other authorities. By the late Heian period, as the samurai class began to rise, the demand for Japanese swords increased significantly, prompting substantial modifications for practical use in combat. Straight blades gradually evolved into curved ones, and manufacturing techniques improved considerably.

With the advent of the Kamakura period, the samurai class came to power, heralding a golden age for Japanese sword forging. Swords were classified into various types to meet specific needs, such as tachi, katana, wakizashi, and tanto. Historical records document as many as 26 distinct types of Japanese swords.

The Japanese sword’s esteemed reputation among the samurai was largely due to its rigorous and intricate manufacturing process. Creating a sword involved numerous meticulous steps, such as refining steel, quenching, forging, shaping, tempering, finishing, and engraving. Each stage demanded precise control over temperature, timing, hammering techniques, and steel quality. The steel, often sourced from high-grade iron sand in Japan’s western Honshu mountains, was vital to the process. Producing a high-quality sword typically required a team of specialized artisans working together for over six months. A single misstep—such as an error in heating or hammering—could render all previous efforts futile.

Historically, not only the Japanese but also their Chinese neighbors were deeply impressed by the sword’s capabilities. During Kublai Khan’s invasions of Japan in 1274 and 1281, the sharpness of Japanese swords left a profound impact on the Mongol cavalry, alongside the natural factors like the so-called “divine winds.” A Southern Song general, Zheng Xin’nan, who participated in these campaigns, remarked in Xin Shi Da Yi that “the Japanese sword is extremely sharp.” During the Ming dynasty, frequent Japanese pirate raids along China’s southeastern coast further cemented the Japanese sword’s deadly reputation.

Despite its military implications, the Ming dynasty admired and envied the craftsmanship of Japanese swords, which they described as “unattainable with our hammering techniques.” Consequently, they heavily imported Japanese swords to equip their troops. By the mid-Ming dynasty, swords consistently accounted for a significant portion of Sino-Japanese trade, with prices often soaring to astronomical levels. For instance, one Japanese sword sold for five times the price of a comparable Chinese weapon.

The Symbolism and Status of the Japanese Sword

In feudal Japan, the value of a good sword extended beyond its craftsmanship and lethality—it was also a symbol of the wearer’s identity and status. Beginning in the Kamakura period, only samurai were permitted to carry swords. A samurai would typically carry two swords: a longer tachi as the primary weapon for combat or self-defense, and a shorter wakizashi as a backup, used if the main weapon broke or was lost. Some warriors, like the famed dual-wielding swordsman Miyamoto Musashi, utilized both swords simultaneously in battle.

For the samurai, a sword was more than a weapon—it was an extension of their honor. Commoners were prohibited from touching or interfering with a samurai’s sword. In 1742, Tokugawa Yoshimune’s Kujikata Osadamegaki codified this practice, granting samurai the “Kiri-Sute Gomen” privilege. This allowed samurai to execute any commoner who defiled their sword, provided they reported the act and offered evidence of provocation.

Feudal lords treated swords as symbols of their power and authority. Legendary swords were revered and treasured even amidst political turmoil. Offering a treasured family blade to a lord as a token of submission often carried a value far greater than land or wealth.

By the late Heian period, artisans began engraving their names on the tangs of their swords as a mark of craftsmanship. Over time, this gave rise to dynasties of swordsmiths who specialized in forging famous blades. These families, often patronized by samurai or feudal lords, held a unique social standing. Among them, the infamous creator of “cursed blades,” Muramasa, stands out.

The Decline and Legacy of the Japanese Sword

The Meiji Restoration marked a turning point in the Japanese sword’s history. In 1876, the Meiji government issued the Haitorei (Sword Abolishment Edict), banning the wearing of swords by anyone outside the police or military. This effectively ended the samurai class and questioned the relevance of bushido, the warrior ethos.

During Japan’s militaristic resurgence in the 1930s, the Japanese sword reemerged as a symbol of nationalist pride. While these modern replicas resembled traditional tachi in appearance, their combat utility had diminished, serving primarily as ceremonial props to evoke the bushido spirit among the populace.

The Spirit of the Japanese Sword

Throughout Japan’s history, the Japanese sword has been intrinsically linked to the samurai. Despite its violent origins, its refined aesthetics and craftsmanship have earned it recognition as an art form. Like the bushido spirit, which blends virtues such as honor, courage, and integrity with a darker history of militarism, the Japanese sword remains a symbol of Japan’s cultural heritage.

Today, iconic swords like “Mikazuki Munechika” and “Doji-giri Yasutsuna” are displayed in the Tokyo National Museum, representing not just exquisite craftsmanship but also the transmission of cultural values. While Japan can no longer forge swords of ancient quality, its dedication to precision and excellence—its shokunin (artisan) spirit—persists in other domains.

The preservation of traditional culture is one of Japan’s defining characteristics. Many ancient Chinese traditions that have faded in their homeland remain alive in Japan, from tea ceremonies to kimono craftsmanship. Even the Japanese sword traces its origins to China’s Tang dynasty swords, showcasing the enduring impact of cultural exchange. Today, Japan’s commitment to preserving and elevating classical traditions has earned it recognition as a global symbol of Eastern culture.
