1800s Japanese Samurai Katana by Iyeshige — Original Mounts, Tameshigiri Inscriptions, High-Status Ownership
This is not a reproduction, a replica, or a decorative piece. This is a genuine 19th-century Japanese katana forged by swordsmith Iyeshige, presented with its original mounts (koshirae), and bearing inscriptions documenting that this blade cut through three bodies in a single stroke. It is a piece of Japanese cultural history of the highest order.
The tameshigiri inscriptions.
The inscriptions on this blade's nakago (tang) document a tameshigiri, a formal sword-cutting test, in which the sword passed through three bodies in a single stroke. Known as a tameshi-mei or saidan-mei (cutting signature), this kind of inscription was considered one of the highest validations a Japanese sword could receive, and it added enormously to a blade's monetary and cultural value. Tameshigiri was a formalized practice in Edo-period Japan (1603–1868) in which premium swords were tested on corpses, typically those of condemned criminals obtained from execution grounds, by specially appointed expert swordsmen called Otameshiyaku. Only the finest, most precisely forged blades could achieve multi-body cuts; the ability to cut through multiple stacked torsos in a single stroke was considered definitive proof of a blade's extraordinary quality. A sword bearing authentic tameshigiri inscriptions recording a three-body cut is a historically significant artifact and indicates a blade of the hisghest quality.
Who carried this sword — and what that tells us
Several indicators point to this sword having been commissioned by or presented to a samurai of high social standing. The tameshigiri testing of a blade was not a routine matter — it was expensive, formally arranged, and documented by appointed officials. Commissioning such a test was itself a statement of wealth, status, and seriousness. Premium swords with documented cutting records were prized possessions of clan leaders, senior retainers, and high-ranking warriors for whom a sword was both a functional weapon and a symbol of hereditary identity. The fact that this sword survives with its original koshirae intact further suggests careful, high-status preservation across generations as ordinary swords were frequently remounted, repurposed, or lost.
The sword was produced during one of the most pivotal periods in Japanese history — the late Edo through early Meiji era, when Japan was transitioning from a feudal military culture to a modernizing nation state. In 1876 the Meiji government issued the Haitorei Edict banning the wearing of swords in public — the first time in centuries that samurai were forbidden to carry their defining symbol. Swords made in the decades immediately preceding this prohibition are among the last produced within a living warrior culture.
This sword is offered as a complete set. It is presented with its original koshirae — the full decorative mounts including handle fittings, guard (tsuba), and scabbard. Also included are a shirasaya (plain unadorned wood storage mounts, the traditional Japanese method of safely housing an antique blade), a wooden blade for safe mounting to the saya when the live blade is not installed and a sword stand for display. The sword has been personally inspected by pre-eminent American Japanese arms expert Mike Yamasaki, and the the blade has been honed and sharpened. For this sword to survive two centuries with original koshirae and associated mounts is a remarkable act of custodianship across many generations.
