Oda Nobunaga was the man who began the unification of Japan — a warlord of ferocious vision who embraced innovation, adopted firearms when rivals clung to tradition, and dismantled the old power structures of feudal Japan with methodical ruthlessness. He called himself the "Demon King of the Sixth Heaven," and his enemies believed him.

His most famous blade, the Heshikiri Hasebe (圧切長谷部 — "Forceful Cutter"), was forged by Hasebe Kunishige, an exceptional smith active in the mid-14th century who worked in the tradition of the great Sōshū school. The sword's name derives from one of the most chilling stories in Japanese sword history: when a servant hid beneath a wooden shelf to avoid Nobunaga's wrath, Nobunaga pressed the blade down onto the shelf and cut clean through it — and through the servant beneath. The story gave the sword its name, and the story has never been forgotten.

The Heshikiri Hasebe is listed in the Kyōhō Meibutsu Chō — the great catalogue of famous Japanese swords compiled in the Edo period — and bears a gold appraisal inlay by the renowned appraiser Honami Kōtoku. After Nobunaga's death, the blade passed to Toyotomi Hideyoshi, and eventually to the Kuroda clan of Fukuoka, in whose possession it remains to this day.

Born a peasant, Toyotomi Hideyoshi rose to become Kampaku — regent of Japan — through sheer force of intelligence, charisma, and audacity. He completed the unification that Nobunaga had begun, built the magnificent Osaka Castle as his seat of power, and enacted the famous katana-gari (sword hunt) — confiscating weapons from the peasant class to ensure that only samurai bore arms. The man who unified Japan through the sword also ensured that only a defined class of people could ever wield one.

His most celebrated blade was the Ichigo Hitofuri (一期一振 — "Once in a Lifetime"), forged by the great Kamakura-period smith Yoshimitsu, who is widely considered the finest maker of tantō in Japanese history. The name reflects the sword's singular quality — this blade, the smith declared, was made but once in a lifetime. Hideyoshi prized the Ichigo Hitofuri above all his possessions, and after his death it was recovered by Tokugawa Ieyasu following the fall of the Toyotomi clan at the Siege of Osaka.

Hideyoshi's relationship with swords extended beyond personal use. He elevated the sword to a cultural and political symbol, commissioning elaborately designed ceremonial blades to reward loyal retainers and to demonstrate his authority to potential rivals. The sword, in his hands, became an instrument of statecraft as much as of warfare.

Tokugawa Ieyasu is remembered as Japan's great patient strategist — the man who waited, survived defeats and alliances alike, and finally emerged in 1603 as the first shōgun of a dynasty that would rule Japan for over 250 years of peace. His sword collection was legendary: swords passed to him from Nobunaga, from Hideyoshi, from defeated rivals, and from the spoils of the Siege of Osaka. He was among the most significant collectors of nihonto in Japanese history.

His personal favourite among all these blades was the Monoyoshi Sadamune (物吉貞宗 — "Auspicious Sadamune"), a wakizashi forged by the brilliant Sadamune, a student of Masamune and one of the great masters of the Sōshū tradition. Ieyasu believed the blade brought victory whenever he wore it into battle — and given his unbroken record of ultimate triumph, it is hard to argue with him.

His most historically significant sword, however, may be the Honjo Masamune — the greatest blade ever attributed to Japan's supreme swordsmith, which became the hereditary treasure of the Tokugawa shōgunate, passed from shōgun to shōgun for over 250 years. In December 1945, the last holder of the Honjo Masamune, Tokugawa Iemasa, surrendered it to Allied occupation forces at the Mejiro police station. It has not been seen since. Its whereabouts remain one of the great unsolved mysteries of the art world.

Miyamoto Musashi is perhaps the most famous swordsman in history — a rōnin (masterless samurai) who won his first duel at the age of 13 and went undefeated in over 60 recorded single combats across his lifetime. He founded the Niten Ichi-ryū school of swordsmanship — the "Two Heavens as One" style — in which the practitioner wields both the long sword and the short sword simultaneously, a technique considered unconventional and even impossible by the traditions of his time.

Musashi's relationship with the sword was philosophically unlike that of any other warrior in this list. Where Nobunaga and Ieyasu valued specific blades as symbols of power, Musashi famously cared little for the quality or cost of his weapon. He is said to have carved his famous sword from a boat oar at the Battle of Ganryūjima — and defeated his greatest rival, Sasaki Kojirō, with it. The sword, for Musashi, was not an object of reverence but a tool — and the true weapon was always the mind that wielded it.

His Go Rin no Sho (The Book of Five Rings), written in 1645 in a mountain cave as he approached death, remains one of the most studied texts on strategy, philosophy, and martial excellence ever written — consulted not only by swordsmen but by military commanders, athletes, and business strategists worldwide. Musashi's legacy is not a blade but a way of thinking.

Hijikata Toshizō was the iron-willed Vice Commander of the Shinsengumi — the elite pro-shogunate police force that enforced order in Kyoto during the turbulent final years of the Tokugawa period. Known as the "Demon Vice Commander" for his strict enforcement of the Shinsengumi code, Hijikata embodied the samurai ideal at its most absolute: loyalty to a cause he believed in, maintained until his death at the Battle of Goryōkaku in Hokkaido in 1869.

His blade is attributed to Izumi no Kami Kanesada — specifically the 11th generation smith of the Kanesada school, based in Aizu Province (modern Fukushima Prefecture). The Kanesada blades of this period were renowned for their sharpness, durability, and practical combat effectiveness — qualities that aligned perfectly with Hijikata's direct, aggressive fighting style. The geographic connection is significant: as the Shinsengumi retreated northward during the Boshin War, Aizu became their stronghold, and a blade from its most prominent smith was a logical choice.

The attribution lacks irrefutable documentary proof — no surviving blade has been definitively linked to Hijikata through physical evidence — but the historical logic is strong, and the Kanesada connection has been reinforced by generations of popular history, fiction, and the deeply held traditions of the Shinsengumi's descendants and admirers.

Sakamoto Ryōma is perhaps the most beloved figure of Japan's Bakumatsu period — a visionary who, in the space of a few extraordinary years, helped broker the alliance between the Satsuma and Chōshū clans that made the Meiji Restoration possible, founded one of Japan's first trading companies, and drafted a blueprint for modern constitutional governance. He did all of this while carrying a Smith & Wesson revolver in one hand and a katana in the other — a man who understood that the era of the sword was ending, and yet remained a swordsman to the last.

His sword was the Mutsunokami Yoshiyuki (陸奥守吉行), forged around 1688 by Morishita Heisuke, a smith who had moved from Settsu Province to Tosa (present-day Kōchi Prefecture) at the invitation of the Tosa domain. The blade was reportedly given to Ryōma by his elder brother, delivered with the assistance of Saigō Takamori and Nakaoka Shintarō, after an assassination attempt on Ryōma at the Teradaya Inn. It was this sword that Ryōma carried on the night of his assassination in Kyoto in November 1867.

In the final moment of his life, Ryōma reached for the Yoshiyuki rather than his revolver — the samurai reflex outlasting the modernist conviction. The assassin cut through the scabbard before the blade could be drawn. Ryōma was mortally wounded and died at 31, just two months before the Meiji Restoration he had helped to engineer would transform Japan forever. The sword's sheath still bears the cut mark from that night.

Honda Tadakatsu was, by almost universal contemporary assessment, the greatest warrior of the Sengoku period — a general who fought in over 57 battles without sustaining a significant wound. Oda Nobunaga, who had seen Honda fight first-hand, reportedly said: "Tadakatsu's bravery knows no bounds. He is a samurai among samurai." He served Tokugawa Ieyasu as one of the legendary "Four Heavenly Kings" — the four great generals whose loyalty and ability made the Tokugawa victory at Sekigahara possible.

Honda's most celebrated weapon was not a sword but a spear — the legendary Tonbokiri (蜻蛉切 — "Dragonfly Cutter"), forged by Fujiwara Masazane, a smith trained within the Muramasa school lineage. The spear takes its name from the story that a dragonfly landed on its blade and was instantly cut in two by the edge — so sharp it could slice without the creature even realizing it had touched the blade. Together with the Nihongo and the Otegine, the Tonbokiri is counted among Japan's three greatest spears.

Honda Tadakatsu died not in battle but from a self-inflicted accident while carving wood — the supreme irony of a man who had survived 57 battles unscathed. His legacy endures as the purest expression of the samurai ideal: absolute loyalty, absolute courage, and absolute mastery of the martial arts.
