The Wakizashi in Daily Life and Battle — The Samurai's Companion Blade

What is Wakizashi—Measurements and Definition

Wakizashi refers to Japanese swords with a blade length of one shaku (approximately 30.3 centimeters) or more but less than two shaku (approximately 60.6 centimeters). Blades shorter than one shaku are classified as "tanto," and those two shaku or longer are classified as "tachi" or "uchigatana." This measurement-based classification has been carried forward into modern legal classifications under sword law.

For samurai during the Edo period, the wakizashi was a "secondary blade" carried at all times in combination with the long sword (uchigatana, two shaku or longer). In the practice of "nihon-zashi"—wearing a matched pair of large and small swords at the waist—the wakizashi was an essential component that demonstrated one's status as a samurai. From high-ranking samurai traveling to Edo for sankin-kotai to lower-ranking samurai of their domains, the practice of wearing two swords was the most visible symbol of samurai status.

Primary Uses of the Wakizashi

The practical applications of the wakizashi manifested in contexts different from those of the long sword (uchigatana).

• Self-defense and close combat indoors: During the Edo period, it was customary to remove long swords from the waist and place them aside when indoors in samurai residences and castle interiors. However, the wakizashi was permitted to be worn even inside buildings. This served as a means of self-defense against sudden threats indoors. With its shorter blade, the wakizashi was easy to maneuver in confined indoor spaces and became an effective weapon in situations where the long sword could not be used.

• Finishing stroke (tomezashi): In battles and duels, the wakizashi or tanto was used for the "finishing stroke"—a decisive blow to ensure the death of an opponent already felled by the long sword. When inserting the blade into gaps in armor, the shorter wakizashi's superior maneuverability made it more advantageous than the long sword.

• Seppuku (ritual suicide): The most symbolic use of the wakizashi was seppuku. In the ritual of seppuku, by which a samurai would choose honorable death, the wakizashi was used to cut the abdomen. This signified that the wakizashi was the most sacred and solemn instrument associated with "a samurai's death." Although kaishakunin—a role performed by another samurai's long sword to sever the head and ease suffering—was used, the individual's own wakizashi was the primary instrument of seppuku.

The Hierarchy of Dai-sho—Wakizashi Mountings and Status

During the Edo period, possessing a matched set of "dai-sho"—a combination of long sword and wakizashi—was proof of a samurai's status. Dai-sho was not merely a pair of tools; custom dictated that they be coordinated with matching mountings (koshirae), with differences in status expressed through the design, materials, and style of the metal fittings.

The highest rank of "koshirae" used as formal ceremonial dress by the shogun's household and daimyo was dai-sho featuring "mishidokoro-mono"—exemplary metalwork by the Gotou family metalworkers. Mishidokoro-mono consisted of three types of metal fittings (mekugi, kozuka, and kogai) coordinated in a unified design by a single master craftsman, and Gotou-family made mishidokoro-mono held the highest status as gifts exchanged among daimyo.

In contrast, wakizashi mountings used by lower-ranking samurai and ashigaru foot soldiers were often simple and utilitarian, featuring iron tsuba and leather-wrapped handles. This disparity was systematized as "mounting hierarchy," with different styles selected according to a samurai's circumstances of appearance—whether in public or private settings.

Regional Characteristics of Wakizashi

While wakizashi-producing regions often overlap with those producing long swords, some regions had specialized tendencies toward wakizashi production.

Contemporary Evaluation and Market for Wakizashi

In the contemporary sword market, wakizashi sometimes receive less prominent treatment compared to long swords (uchigatana and tachi), but their artistic value is equivalent to that of long swords. In fact, well-preserved wakizashi often show less wear than long swords and can have higher aesthetic value in some cases.

Price ranges vary greatly depending on condition, maker, and era, but typical unsigned wakizashi from the Edo period range from several hundred thousand yen upward, while signed works by renowned swordsmiths or exceptional koto pieces can reach several million to tens of millions of yen. Wakizashi accompanied by NBTHK conservation certificates or special conservation certificates are particularly valued by overseas collectors, as the authentication guarantee and grading are clearly established.

Wakizashi represent the sword category that most intimately embodies "a samurai's everyday life." While long swords symbolized public and martial contexts, wakizashi symbolized a samurai's private spaces, personal honor, and readiness for death. This cultural significance continues to imbue wakizashi with value beyond being merely "a short sword" in contemporary times.
