How does a short sword compare to a tanto in Japanese sword tradition?
Updated Feb 2026
In Japanese sword tradition, a tanto is a short sword - the two terms overlap significantly, with tanto being the Japanese-specific term and short sword being the more general English equivalent. A tanto has a blade length of approximately 15 to 30 centimeters, which places it well below the wakizashi and katana in the Japanese size classification system. The tanto was historically a weapon carried by samurai as a backup to the longer swords and was also used for ritual purposes including the formal suicide ritual known as seppuku. In Japanese blade classification, a sword with a blade under 30 centimeters is a tanto, a blade of 30 to 60 centimeters is a wakizashi, and a blade over 60 centimeters is a katana or longer sword type. The hamidashi tanto is a tanto variant with a small guard, as distinguished from the ko-tanto with no guard and the standard tanto which may have a full tsuba. The swords in this collection labeled as short swords span the tanto length range in these various forms.
