It’s unimaginable to think about Japan without its iconic swords, like the katana, wakizashi, and tanto. It would be like imagining the US without the Statue of Liberty or Paris without the Eiffel Tower. Japanese swords are more than a symbol of a country, however. These tools of warfare are the manifestation of a divine entity or “kami.” For many Japanese and outsiders, the Japanese sword, especially the katana, is the soul of the legendary Samurai.
Japanese sword-making is in a class of its own, with a rich history spanning over 1,500 years, featuring over 12,000 katana kaji or Japanese swordsmiths and over 30,000 makers of sword furniture like mountings and fittings. Of this number, 15 are the most famous. Who are they, and what did they contribute to the growth and evolution of iconic Japanese swords?
Join us in exploring the world’s top 15 famous Japanese swordsmiths, from ancient to contemporary Japan.
Ancient Masters of the Japanese Blade
Japanese swordsmithing has been around for at least 1,500 years, although determining the who’s who in unrecorded history can be challenging. However, scouring through countless archives and anecdotal reports, we’ve listed 5 of ancient Japan’s most historic (read, revolutionary) swordsmiths. The philosophies of these masters of the blade echo through eternity, and even 21st-century locksmiths still adhere to the swordmaking principles of Japan’s greatest swordsmiths. It should set you up to understand everything you need to know about the Samurai sword.
1. Goro Nyudo Masamune

Considered by many sword experts and Japanese cultural savants as one of the greatest Japanese swordsmiths, Goro Nyudo Masamune was instrumental in catapulting Japanese blades and craftsmanship to the world stage. Showcasing his remarkable swordsmithing prowess during the late Kamakura Period (between 1288 and 1328), Masamune perfected the Soshu-den style. This technique created a Japanese sword with unbelievable strength and sharpness, and it could slice through enemies with a single slash.
Masamune’s Soshu-den style also made the katana and other Japanese swords works of art. These blades are renowned and valued for their unparalleled aesthetic beauty. Masamune’s blades, fondly called “Masamune’s masterpieces,” often feature a harmonious balance of hada or blade pattern and exquisite martensite crystals called nie.
A millennium later, many of Masamune’s swords, including Japan’s perfect sword, the legendary Honjo Masamune, are revered as Japanese national treasures. These blades embody the pinnacle of Nippon metallurgy, while Masamune’s influence shaped sword-making traditions for generations. Unsurprisingly, Masamune is often viewed as the embodiment of excellence in Japanese swordsmithing.
2. Amakuni Yasatsuna

Centuries before Masamune transformed Japanese sword-making, Amakuni Yasatsuna developed and created some of the earliest versions of the tachi, the Samurai katana’s predecessor. Yasatsuna created long, reliable, curved blades for warriors during the Nara Period between 710 and 794 AD.
Sword experts regard Yasatsuna for his durable blades with superior cutting abilities and intricate hada patterns. The Dojigiri Yasatsuna exemplifies Yasatsuna’s exceptional craftsmanship. Unsurprisingly, this sword is one of Japan’s “Five Swords Under Heaven” or Tenka-goken. Legends say the Dojigiri or “Slayer of Shuten-doji” was used by the Heian folk hero and Samurai warrior Minamoto no Yorimitsu to slay the Shuten-doji monster.
Yasatsuna’s innovations laid the groundwork for the development of Japanese swordsmithing, influencing techniques and styles that persisted for centuries, including Masamune’s era.
3. Sanjo Munechika

Following in the footsteps of Yasatsuna, Sanjo Munechika is a highly acclaimed Japanese swordsmith known for forging and smithing the Mikazuki or “Crescent Moon” sword, a Heian Period tachi, revered for its beautiful crescent-moon-shaped temperline (hamon). It was the favorite sword of Ashikaga Yoshiteru and is one of Japan’s “Five Swords Under Heaven.”
Munechika’s works are a thing of beauty. It marked an era when swords transitioned from mere tools of war to objects of artistry. His swords combined precision functionality with breathtaking beauty. Unsurprisingly, many of his swords were used by the emperor and nobles. He refined Yasatsuna’s techniques, turning deadly swords into artwork, and laying the foundation for the Yamashiro sword-making tradition. This sword-making school is venerated for its elegant swords.
Sanjo Munechika stands out for his dedication to impeccable craftsmanship, enduring blade sharpness, and elegant proportions. He is a foundational figure in Japanese swordsmaking.
4. Hikoshiro Sadamune

A Masamune disciple, Hikoshiro Sadamune’s contributions to Japan’s swordmaking excellence nearly rival his master’s. Many Masamune scholars consider Sadamune one of the legendary swordsmith’s most accomplished students.
Sadamune’s Japanee blades are characterized by their perfect balance, refined craftsmanship, and intricate details. The blades feature elegant hamon patterns, especially his irregular wave tempering pattern. Scholars see Sadamune’s swordmaking style as gentler than that of his master, Masamune. He is credited for advancing Masamune’s pioneering techniques while adding his distinct style.
One of Sadamune’s most distinguished works is the Tachi Sadamune, a long, curved sword with unmatched aesthetics and dependable functionality. Many consider Sadamune a “genius artisan,” reflecting his role in elevating Japanese sword smithing and sword-making to an art form. It secures his place among the greatest swordsmiths in history.
5. Sengo Muramasa

Few Japanese master swordsmiths can be as controversial yet still legendary as Sengo Muramasa. This skilled swordsmith of the Muromachi Period is recognized for his ultra-sharp blades—so sharp that pundits called his swords “blood-thirsty.” Legends say if one must draw a Muramasa sword from its scabbard, the blade must draw blood before re-sheathing; lest the Samurai is cursed. Some say the sword forces its wielder to wound himself or commit suicide before it can be returned to the scabbard.
It is worth noting that Muramasa swords are a favorite of Tokugawa Ieyasu’s Mikawa samurai. Unfortunately, when these warriors fell in battle, people assumed it was because of the extreme sharpness of Muramasa swords. Hence, they believed it was cursed.
Cursed or not, Muramasa swords, like the Myoho Muramasa or Sublime Dharma sword (an Important Artwork in Japanese Culture), are revered for their exceptional sharpness, which can only come from the skilled hands of Sengo Muramasa.
Muramasa’s work during the Muromachi Period featured innovative techniques that resulted in hyper-durable, well-balanced, and super-sharp swords with signature temperlines. When combined with Muramasa swords’ aura of mystique, it’s unsurprising that many sword enthusiasts and collectors seek such swords. His contributions to metallurgy and focus on functionality have left a lasting impact on the Japanese tradition of exceptional sword-making.
Edo Period Innovators
From the ashes of the troubled, conflict-ridden Sengoku Period came a time of internal perpetual peace, strict social order, economic growth, a stable population, and the growing popularity of arts and culture. While Japanese swords remain essential, they require modification to suit ceremonial requirements and other social gatherings. Hence, the Edo Period (or Tokugawa Shogunate) bred a different class of Japanese swordsmiths – artistic yet devout in the ancient ways of swordmaking.
6. Izumi no Kami Fujiwara Kunisada
Under the tutelage of one of Japan’s most famous Osaka Shinto smiths, Horikawa Kunihiro, Kunisada etched a name for himself in the world of Japanese swordsmithing during the early Edo Period. He is well-known for katana and wakizashi swords, featuring exceptionally sharp blades, called Owazamono. Interestingly, some scholars believe Kuinisada blades can rival Muramasa swords in extreme sharpness.
Also known as Tsuda Sukehiro II, Kunisada was an influential swordsmith known for creating swords with distinct hamon featuring strong nie. He popularized the toranba billowing wave temperline style, giving Kunisada’s blades a unique charm without losing their practical excellence.
Kunisada’s work embodied the refined artistry of Japanese swordsmithing during the early parts of the Edo Period, making these blades highly sought after by sword collectors and enthusiasts. These swords represent the pinnacle of Osaka sword-making traditions. Unsurprisingly, it’s where you can get some of the best Japanese swords in the world.
7. Nagasone Kotetsu

Although Kotetsu started as a blacksmith specializing in armor, this famous Edo Period craftsman transitioned to sword-making to become one of Japan’s most celebrated swordsmiths. Like many swordsmiths of the era, Kotetsu focused on improving the katana’s aesthetic qualities by integrating highly intricate horimono of blade carvings, including Sanskrit symbols, gods, dragons, and other mythical creatures and deities. One of his best works featured a juzuba hamon pattern, resembling a row of rosary beads.
His blades are not only extraordinarily beautiful. They are robust and sharp, too—they could cut through helmets, rendering such body protection useless against a skilled Samurai wielding a Kotetsu sword.
Kotetsu’s work exemplifies the pinnacle of Japanese sword-making, characterized by a balance of elegance and strength, making his swords highly valued by Samurai and collectors. His innovative techniques and meticulous craftsmanship solidified Kotetsu’s legacy as one of the finest swordsmiths of his time.
8. Yasutsugu Kichizaemon
Traditional Japanese sword-making relied on satetsu ironsand to make tamahagane steel. While the Edo Period remained relatively peaceful, this resource was becoming scarce. Enter Yasutsugu and his pioneering efforts to introduce foreign or imported steel (nanban tetsu) into tamahagane steel to create equally stunning, sharp, and durable blades.
Yasutsugu wasn’t only instrumental in introducing foreign elements to traditional swordsmithing. He also specialized in saiha – re-tempering older swords to restore their edge. Moreover, his blades featured deep, consistent sugaha hamon with small undulations. The blades had horimono or carvings. Yasutsugu was the first to inscribe the Tokugawa Shogunate’s family crest – the holy oak symbol – on the sword’s tang.
Yasutsugu’s works seamlessly blended traditional and modern techniques, ensuring strong, sharp, and beautiful swords while fueling the continuing evolution of Japanese sword-making.
9. Noda Hankei
An esteemed sowrdsmith during the second half of the Edo Period, Noda Hankei is well-recognized for his phenomenal artistic approach to sword-making, often following the Soshu Den tradition (a system originating during the mid-Kamakura Period in the 12th century).
He is known for his unique and often experimental sword designs, including intricate blade carvings and elaborate temperline patterns.
Hankei might not be as popular as Masamune or Muramasa, but this Japanese swordsmith can hold his own. His work reflects a deep understanding of metallurgy and a commitment to pushing the boundaries of traditional swordsmithing.
10. Minamoto no Kiyomaro
Many scholars consider Kiyomaro the “last master swordsmith,” figuring prominently during the late Edo Period. His swords are celebrated for their perfectly executed hamon, elegant hada, and robust construction. Some say Kiyomaro was Masamune reincarnated. His blades featured stretched kissaki, fine-wood grain ji-gane, and shallow sori.
It’s worth pointing out that demand for Samurai swords was waning around this time. Kiyomaru’s efforts to revive traditional sword-making techniques are recognized by many as instrumental in keeping the spirit of the Samurai (and by extension, traditional swordsmithing) alive.
We wouldn’t have contemporary Japanese swordsmithing masters without Kiyomaro’s dedication to safeguarding Japan’s cultural heritage. Unsurprisingly, many collectors and sword enthusiasts seek Kiyomaro swords (despite being expensive) for their exceptional quality and historical significance.
Famous Japanese Katanakaji of the 20th and 21st Century
Contemporary Japanese swordsmiths carry forward the rich legacy of crafting katana, tanto, wakizashi, and other Japanese blades. They keep the ancient art of swordsmithing while embracing innovations to meet modern tastes. Modern katana kajis keep the Samurai spirit alive, uphold the cultural heritage of Japanese sword-making, and guarantee its relevance in the 21st century while inspiring new generations of swordmakers, craftsmen, and enthusiasts worldwide.
11. Yoshihara Yoshindo
Yoshihara Yoshindo is one of the 20th-century’s most celebrated swordsmiths, having descended from 10 generations of famous sword-makers. He is one of Japan’s Living National Treasures, recognized for his unmatched dedication to preserving traditional sword-making techniques, particularly the Masamune Soshu tradition (although Yoshihara switched to Bizen-style sword-making in the 1970s.

15. Ono Yoshimitsu
While Yoshimitsu isn’t a Living National Treasure (yet), there’s a good chance he will. Born in 1948, Ono Yoshimitsu is one of Japan’s best swordsmiths—a Mukansa, revered by experts as one of the greatest honors a swordsmith can receive.
