Naginata vs Nagamaki: Comparing Japanese Halberd Forms and Their Battlefield Use

Naginata and Nagamaki — What's the Difference Between These Similar-Looking Long-Shafted Weapons?

The naginata and nagamaki are both long-shafted weapons with blades attached to long handles, and their similar appearance often leads to confusion. However, they have clear differences in blade shape, handle length, usage, and historical development, and from a weapons history perspective, they are classified as distinct weapons.

When comparing historical documents, scrolls, and actual weapons, the difference between the two is most clearly evident in the "ratio of blade to handle." The naginata tends to have a long handle and shorter blade (handle 6-7: blade 3-4), while the nagamaki has a handle and blade of roughly equal length or a relatively longer blade (handle 5: blade 5-6). However, there is significant variation depending on period, region, and maker, and there are aspects that cannot be classified based solely on measurements.

Naginata Form and Origins — Development from the Late Heian Period

The prototype of the naginata dates back to the late Heian period (11th-12th centuries). The "naginata" — a long blade formed by extending the blade of a tachi into an elongated shape — was initially used by mounted warriors to sweep aside footsoldiers. The weapon's name derives from its primary function: the sweeping motion called "nagu" (striking at an angle).

The blade has a pronounced curve (sori from the base to mid-length), and the kissaki (point) is relatively small and rounded. The blade is single-edged, with the spine (mine) given thickness for durability. The handle is made of wood with an elliptical cross-section, finished with lacquer and leather wrapping, with an ishitsuki (butt cap) at the end to also serve as a thrusting weapon.

During the Kamakura and Nanboku-chō periods, the naginata developed into one of the primary weapons of footsoldiers, and warriors wielding naginata are depicted in the Mōko Shūrai Ekotoba. Later, when long spears rose in prominence during the late Muromachi and Sengoku periods, the naginata's role on the battlefield declined. However, in the Edo period, "naginata-jutsu" was established as a self-defense technique for female warriors and was passed down to the modern martial art of "naginata-dō."

Nagamaki Form and Combat Role

The nagamaki is a weapon that developed during the Nanboku-chō and Muromachi periods (14th-16th centuries), with a long blade (some with edge lengths exceeding 60-90 cm), and due to its long handle as well, its total length sometimes exceeds that of the naginata. Its hamon and jigane characteristics follow those of the sword, with high-quality blades characteristically manufactured using swordsmith techniques.

Due to its origins as "a weapon created by extending a tachi's handle," the nagamaki's handle often uses materials of the same type as tachi-koshirae (sword fittings). Furthermore, some nagamaki were designed so that if the blade were removed and fitted with a shorter handle, they could serve as ordinary tachi, allowing for versatile use of the same blade.

The reason the nagamaki was valued lay in its advantage in "blade length and distance management" when engaged with mounted warriors and long-shafted weapons. While the naginata specialized in sweeping cuts, the nagamaki allowed for diverse techniques including thrusts, overhead cuts, and sweeps. Records from battles during the Nanboku-chō period indicate that warriors known as "ōdachi users" wielded the nagamaki and achieved distinction.

Battlefield Applications — Differences in Usage and Formation

The use of naginata versus nagamaki varied depending on battlefield conditions, formations, and opponents.

Situations where the naginata was effective

• Repelling dense infantry (footsoldiers): spreading horizontally in line to deliver sweeping strikes
• Horizontal sweeping in confined spaces such as castle gates and corridors
• Anti-cavalry tactics for striking at the legs of mounted warriors' horses

Situations where the nagamaki was effective

• Single combat-like exchanges in open field battles
• Distance contests against other long-shafted weapons (long naginata, spears)
• Situations where an individual's martial skill could be maximized

While the nagamaki developed against the backdrop of intense individual combat during the Nanboku-chō period, in Sengoku-period group tactics, spears and bows were emphasized over individual weapons, causing the nagamaki to relatively decline, and the naginata shifted into the domain of female martial arts. This change demonstrates that the evolution of weapons is inseparably linked to changes in tactics.

Naginata and Nagamaki in the Modern Era — Status as Martial Art and Art Object

Today, the naginata is carried on as the martial art "naginata-dō," centered on female practitioners, with school martial arts and ranked system training organized under the All Japan Naginata Federation. The nagamaki has no corresponding established modern martial art and is often treated in the context of martial arts research and reconstructed practice of classical martial techniques.

As art objects and museum pieces, both naginata and nagamaki remain as actual specimens in sword museums, local samurai residences, and old houses, with some designated as Important Cultural Properties by the national government. Due to their scarcity compared to swords, they circulate less in the collector market, but high-quality nagamaki from the Nanboku-chō period command high rarity value, with some examples selling at auction for several million to tens of millions of yen.

The differences between the naginata and nagamaki extend beyond mere weapons morphology, reflecting differences in warfare styles, period sensibilities, and user classes in which each developed. Comparing the two provides a perspective for comprehensively viewing the evolution of Japanese weapons history, samurai culture, and martial arts.
