How does a tanto differ from a wakizashi in terms of size and use?
Updated Feb 2026
The tanto and wakizashi are both short Japanese swords, but they occupy distinct size categories with different historical roles. A tanto has a blade length of 15 to 30 centimeters and an overall length in its saya of 30 to 45 centimeters. A wakizashi has a blade length of 30 to 60 centimeters and an overall length of 50 to 80 centimeters. The boundary between the two categories is approximately 30 centimeters of blade length - blades below this are tanto, blades above are wakizashi. Historically, the tanto was the personal side arm of samurai and was worn alongside the katana, while the wakizashi served as the shorter sword in the formal daisho pairing. The tanto's compact size made it useful in confined spaces and in situations where the full reach of a katana was not available. As collectibles, tanto display differently from wakizashi: the shorter blade is more appropriate for desk and shelf display at close examination range, while the wakizashi occupies an intermediate space between the compact tanto and the full-length katana.
