What is a miao dao and how does it compare to a Japanese nodachi?
Updated Feb 2026
The miao dao is a Chinese two-handed long saber that developed during the Ming and Qing Dynasty periods, characterized by a long single-edged curved blade on a two-handed grip with a guard between blade and handle. Miao dao blades typically range from 35 to 50 inches in length, with the complete sword reaching 55 to 65 inches overall including the two-handed handle. The Japanese nodachi or odachi is the closest historical parallel - also a two-handed long sword with a long curved single-edged blade, typically 40 to 60 inches in blade length, that is associated with the Japanese samurai tradition. The two forms developed in historical proximity (both reaching mature development in the 14th to 17th century period) and show similarities in their overall approach to maximizing reach through blade length combined with a two-handed handle. The primary differences are in the specific blade geometry - miao dao blades show Chinese dao influence in their cross-section and curve profile, while nodachi blades follow Japanese sword geometry conventions - and in the fitting and handle traditions, which are distinctly Chinese and Japanese respectively.
