Hasebe Kunishige

From Yamashiro to Sōshū—Hasebe Kunishige's Unique Position

Hasebe Kunishige was a sword smith who flourished in Kyoto during the Namboku-chō period. While his origins are subject to various theories, his most distinctive characteristic is his unique style, which was grounded in the Yamashiro tradition while actively incorporating the techniques of the Sōshū tradition. He is counted among the Ten Great Disciples of Masamune and is highly regarded as a sword smith who demonstrated exceptional skill among the Yamashiro smiths of his time, particularly influenced by the Sōshū tradition.

After the fall of the Kamakura shogunate, during the tumultuous Namboku-chō period when the influence of the Sōshū tradition spread throughout the country, Kunishige established his residence in Yamashiro while studying the robust jigane and hamon of the Sōshū tradition, elevating these techniques into his own distinctive style. The jigane is characterized by masame mixed with itame, with deep and thick nie. The hamon displays intense patterns of gunome-midare or near-all-hardened styles, embodying the robust beauty characteristic of the Namboku-chō period.

Wide and Robust—The Blade Aesthetics of the Namboku-chō Period

Most of Kunishige's works possess the wide, long, and robust construction style that was fashionable during the Namboku-chō period. Blades in the ōdachi (great tachi) style—with wide blade width, thick spine, and prominently extended kissaki—reflect the practical demands of warfare during tumultuous times, while also showcasing Kunishige's exceptional prowess as a sword smith, representing true masterworks.

In addition to tachi, fine examples of tantō and katana also survive, all combining beautiful jigane with intense hamon. The jigane, with flowing masame through itame and thickly accumulated nie, possesses a distinctive presence that could be called 'Kunishige-hada' (Kunishige surface). While his style inherits the traditions of Osafune Kanemitsu of Bizen and Masamune of Sōshū, it does not lose the elegance of Yamashiro, maintaining a unique synthesis of multiple traditions that continues to captivate viewers.

Heshikiri Hasebe—Oda Nobunaga's Pressing-Cut Anecdote

The blade that secured Kunishige's fame for posterity is undoubtedly the 'Heshikiri Hasebe.' Currently designated as a National Treasure and housed in the Fukuoka City Museum, it is known as one of the most celebrated blades in the Kuroda family collection.

The name 'heshikiri' (pressing-cut) derives from an anecdote involving Oda Nobunaga. When Nobunaga rebuked a tea attendant who hid under a shelf, he reportedly drew his sword and pressed-cut through the shelf itself. The name comes from the fact that he 'pressed-cut' (heshikiri) through the shelf, and the anecdote is widely known as illustrating both Nobunaga's stern temperament and the extraordinary cutting ability of Kunishige's blade.

Nobunaga bestowed this sword upon Kuroda Kanbei (Takutaka), and it became a treasured heirloom of the Kuroda clan. Later, when Kuroda Nagamasa established the Fukuoka Domain in Chikuzen, the Heshikiri Hasebe was passed down as the domain's treasured blade through successive generations and is carefully preserved in the Fukuoka City Museum to this day. The beauty of the blade's form, combined with its historical significance tied to Nobunaga and the Kuroda clan, secures its position as one of the most famous swords in Japanese blade history.

Hasebe Kunishige's Sword-Making Technique—The Fusion of Sōshū and Yamashiro Traditions

From a technical perspective, Kunishige's sword-making was at the forefront of his era. By combining the refined jigane-forging techniques he learned as a Yamashiro smith with the nie techniques of the Sōshū tradition, he created a distinctive jigane beauty that was unmatched by his peers.

The hamon primarily consists of gunome-midare with deep nie or all-hardened style, and Sōshū-specific features such as kinsuji (golden lines) and sunagarashi (sand-flow patterns) are evident throughout. When polished, the nie in the edge gleams white, creating a striking contrast with the dark, subdued forging surface of the jigane. This interplay of light and shadow is the defining characteristic that allows Kunishige's works to be instantly recognized.

Additionally, the nakago (tang) is slim with fine file marks, and the signature characters are carved deeply and boldly. The signature 'Hasebe Kunishige' is rendered in powerful strokes, conveying the maker's confidence and conviction. While signed works by his hand are not numerous, all that survive are ranked as first-class, and their authenticity is highly reliable in appraisals.

Kunishige's Connection to Sendai and the Northeast, and His Historical Legacy

While the Heshikiri Hasebe passed from Nobunaga to the Kuroda family, from the perspective of the relationship between swords and military leaders, Date Masamune of the northeast and Sendai also cultivated a similar sword culture. Masamune's beloved sword, the Shokudaikiri Kanemitsu (crafted by Osafune Kanemitsu), exemplifies the iconic status of a great general's blade, and like Kunishige's works, it has remained a symbol of an illustrious warrior's legacy. The fact that Kunishige's blades, born in the turbulent Namboku-chō period, took deep root in both subsequent Japanese blade aesthetics and warrior culture provides an important perspective when viewing Japanese sword history from Sendai, where TOUKENZA is based.

Hasebe Kunishige fused two great traditions—Yamashiro and Sōshū—and embodied the robust beauty befitting the tumultuous Namboku-chō period. By leaving behind the Heshikiri Hasebe, a supreme blade of legendary renown, his name is forever inscribed in Japanese sword history.
