Why do samurai carry two swords?

The short answer

Samurai carried two swords known as the daishō12. This pair consisted of a longer katana and a shorter wakizashi14. The wakizashi was a secondary weapon designed for self-defense and use in confined spaces where the katana was impractical1. Carrying these blades represented the samurai's authority, honor, and way of life12. While the wakizashi was an inseparable companion to the katana1, the daishō eventually became a symbolic emblem of power for aristocratic bureaucrats3.

What the evidence shows

Practicality and Defense

The wakizashi served as a shorter blade for self-defense1. Its length allowed it to be drawn and used effectively in indoor settings or confined quarters1.

Daggers called tantō were also carried for personal protection and close combat2. The wakizashi was often the preferred choice for these situations2.

Social Status

The daishō represented the social power and personal honor of the samurai2. Only samurai were permitted to wear this specific set of two swords2.

By the end of the Tokugawa era, the daishō served as a symbolic emblem of power for samurai who were aristocratic bureaucrats3.

Legal Requirements

The Tokugawa shogunate required samurai to wear a katana and a shorter sword in pairs2. Following a law passed in 1629, samurai on official duty were required to wear two swords3.

Samurai were also granted the privilege of carrying two swords3.

Our take

This part is our own interpretation, not a sourced finding.

It is striking that the daishō transitioned from a practical tool for close-quarters defense to a symbolic emblem of bureaucratic power3. This shift shows how a functional weapon can become a primary marker of social identity12.

What we can't say for sure

The sources do not state the specific reason why samurai were given the privilege of carrying two swords3. They also do not state the specific reason why they were required to wear two swords while on official duty3.
