Types and Structure of the Naginata—The Complete Overview of the Weapon Passed Down by Female Martial Artists

What is the Naginata—Its Position in the Japanese Sword System

The naginata is a type of Japanese sword characterized by a curved blade attached to the end of a long shaft, forming a unified structure between blade and haft. It is a long-hafted weapon. The name "naginata" is said to derive either from "nagu"—the action of sweeping broadly—or from the archaic word "nagatana" (long sword) that became corrupted over time.

In sword classification, the naginata belongs to the category of "long-hafted weapons" and is distinct from "worn swords" such as the tachi and uchigatana. While in modern usage the terms "naginata" and "chōtō" (long sword) are sometimes used interchangeably, strictly speaking, chōtō can also refer literally to a long blade.

Structure of the Naginata—Components of Blade, Haft, and Butt

The main components of a naginata are as follows.

Blade (natane): A single-edged curved blade, typically 1 to 2 shaku (approximately 30 to 60 cm) in length. It features a spine (mune) and edge (ha), with the curve (sori) varying by period and school. The tang (nakago) is inserted into the haft and secured with a mekugi (peg). Blade shapes vary widely, from gracefully curved forms like the "nadening" to nearly straight forms like the "sugunaginata."

Haft (e): Made of wood with a standard elliptical cross-section. The length typically ranges from 5 to 8 shaku (approximately 150 to 240 cm). Unlike the handles of tachi or uchigatana, the grip section is often left unwrapped in cloth or leather, though this varies by school.

Butt (ishizuki): A metal ferrule attached to the end of the haft, serving to protect the haft when thrust into the ground and to counter attacks from behind.

Seppa and habaki: The naginata also features ferrule-like fittings that reinforce the junction between blade and haft.

Historical Development of the Naginata—From the Heian to Edo Period

The origins of the naginata are believed to date to the late Heian period, with the earliest historical records documenting its use by Buddhist warrior monks (sohei). Historical texts record that armed monks at major temples such as those in Nara and on Mount Hiei used long-hafted weapons to counter mounted samurai.

During the Kamakura through Nanboku-chō periods, the naginata was widely used on the battlefield as the primary weapon of infantry. It excelled at the sweeping motion to strike the legs of mounted warriors and was well-suited for group deployment in close combat. During the turbulent Nanboku-chō period (14th century), naginatas grew larger, and the "ōnaginata" (great naginata) emerged.

With the advent of the Muromachi period, the spear (yari) gradually replaced the naginata on the battlefield. The spear was easier to manufacture and exceeded the naginata in length, making it better suited for organized group deployment in large-scale military campaigns. Consequently, the naginata relinquished its position as the primary weapon on the battlefield to the spear.

During the Edo period, the naginata established itself as a "woman's weapon," a cultural institution practiced by samurai women for self-defense and martial arts. Naginata training became part of the bride-training curriculum for daughters of samurai families, and the notion that "the naginata is a woman's weapon" became deeply embedded in society.

Types of Naginata—Classification by Shape and School

The naginata can be classified into multiple types based on its shape and the schools that use it.

Nadening (graceful naginata): Characterized by an elegantly curved blade, this form is common among older naginatas from before the Muromachi period. With a pronounced curve along the edge, it is well-suited for sweeping motions.

Shōbu-zukuri naginata (iris-patterned naginata): Featuring a cross-section resembling iris leaves in the shinogi-zukuri style, this form combines durability and sharpness. It is commonly seen as a practical tool among samurai.

Sueki to Shintō-period naginatas: Crafted by master blade smiths, these naginatas sometimes feature blade quality comparable to tachi and uchigatana. Most extant naginatas of artistic merit date from this period.

Modern naginata (training): Specialized training equipment designed for contemporary naginata-do competitions. Bamboo or wooden practice naginatas are used in training, with protective armor worn as standard in matches.

The Tomoe-style naginata and Shizuka-style naginata are regarded as the two major forms of the weapon. The Tomoe-style features a pronounced curve and bold proportions, said to derive its name from Tomoe Gozen, the female warrior famous for her exploits in the Genpei War. The Shizuka-style displays an elegant form with a subdued curve, named after Shizuka Gozen, the concubine of Yoshitsune. In classical schools, the two major stylistic divisions of Tomoe-school and Shizuka-school correspond to these shape differences, and the degree of blade curvature has traditionally served as an indicator for determining a school's lineage.

Modern Naginata-dō—Its Continuity as a Women's Martial Art

In contemporary times, the naginata is inherited as a systematized martial sport known as "naginata-dō." The All Japan Naginata Federation (established in 1955) oversees the practice, with training conducted at schools and martial arts halls throughout the country.

A distinctive feature of naginata-dō is that over 90% of competitive participants are women, a result of the cultural tradition of the "woman's martial art" inherited since the Edo period. However, male practitioners have been increasing in recent years, and mixed-gender competitions are being developed.

A ranking system recognized by the All Japan Naginata Federation has been established, with grades from first dan through eighth dan and titles such as renshi, kyoshi, and hanshi. International tournaments are held, and active efforts to promote the sport throughout Europe, America, and Asia are underway.

The preservation and study of historical naginatas as art objects is undertaken by institutions such as the Society for the Preservation of Japanese Art Swords, and multiple naginatas have been designated as Important Cultural Properties. Collectors of swords apply the same artistic evaluation standards to naginatas as they do to tachi and uchigatana.

According to statistics from the All Japan Naginata Federation, approximately 50,000 people participate in the sport, making it one of the largest female-centered martial arts competitions in Japan. In classical schools, traditions such as Jikishin Kage-ryū and Masaki-ryū have transmitted naginata techniques to the present day, forming the foundation of modern naginata-dō's technical system. Internationally, the World Naginata Federation oversees organizations in various countries, and competitive and promotional activities are conducted across multiple nations, including Europe, America, and Asia.
