What makes tachi koshirae different from katana mounts?
Updated Mar 2026
A tachi koshirae is designed for suspension from the waist with the edge facing downward, which directly influences its proportions and fittings. The saya on a tachi typically features two sets of kurikata - the knobbed fixtures through which the sageo cord is threaded - allowing the sword to hang securely in the correct carry position rather than being thrust through a sash as a katana would be. The tsuka (handle) is also generally longer and more curved to accommodate the different draw angle. On display, a complete tachi koshirae with matched sageo cord, ito wrap color, and tsuba design presents a far more unified aesthetic than a blade mounted with uncoordinated fittings - which is why collectors pay close attention to the harmony of the full ensemble rather than focusing on the blade alone.
