What is the correct blade length for a wakizashi versus a tanto and a katana?
Updated Feb 2026
The Japanese sword classification system defines blade categories by specific length ranges that create a clear hierarchy. A tanto has a blade below 30 cm - it is classified as a knife or dagger rather than a sword. A wakizashi occupies the range from 30 to 60 cm blade length, defining it as the shoto or short sword category. A katana occupies the range above 60 cm blade length, typically 70 to 80 cm in most production pieces. In the daisho pairing, the katana is the daito or long sword and the wakizashi is the shoto or short sword - the two together represent the complete samurai blade set. A tanto is shorter than a wakizashi and is a separate category rather than a variation of the companion blade format. The visual hierarchy of these three lengths is immediately apparent when pieces are displayed together.
