The late Heian and Kamakura periods witnessed the rise of the warrior class, the Genpei War, and the establishment of the Kamakura shogunate. In this world, the tachi was carried edge-down from the belt and used primarily by mounted warriors.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eOver the centuries, many of these early swords were shortened to suit changing fashions and methods of combat. As warfare evolved and the uchigatana became dominant, older tachi were frequently altered to remain practical. Consequently, examples that preserve their original proportions have become increasingly uncommon.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe present blade offers a rare glimpse into that earlier world.

The deep koshi-zori, long tachi form, ubu tang, and overall workmanship point toward a period significantly earlier than most surviving Japanese swords.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eIn the opinion of the polisher, even the most conservative assessment would place the blade no later than the late Kamakura period, while an origin in the late Heian or early Kamakura period remains a possibility.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eAmong the traditions that may be considered, the workmanship strongly recalls the Ko-Naminohira school.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe Naminohira tradition of Satsuma Province is regarded as one of the oldest continuously active swordmaking lineages in Japan, with origins traditionally traced to the late Heian period. Unlike many later schools that developed increasingly elaborate temper patterns, early Naminohira work is often appreciated through its shape, steel, and overall atmosphere rather than conspicuous activity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eParticularly noteworthy is the jihada of this blade. The steel is primarily forged in itame-hada, while flowing masame appears along the ha and shinogi. This combination is frequently encountered in early Naminohira-related workmanship and contributes significantly to the blade's old appearance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eEqually important is the consistency between the blade's shape, steel, and tang.

The deep koshi-zori creates an elegant profile strongly associated with early mounted combat. Despite its substantial dimensions, the blade retains a balanced appearance that reflects the practical requirements of the period in which it was forged.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe blade remains ubu and retains a single mekugi-ana. Particularly notable is the position of the mekugi-ana, located significantly lower on the tang than is commonly seen on later swords. Together with the preserved shape of the nakago, it contributes greatly to the impression of age.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe jihada displays itame-hada with flowing masame along the ha and shinogi.
