The purpose of this study is to clarify the process of acceptance regarding the characteristics of Japanese swords in
Ji-Xiao-Xin-Shu “紀效新書”.
Ji-Xiao-Xin-Shu is a Chinese book on martial arts that was written in the 16th century. There were two editions of this book, one was published around 1560-1566 (the earlier edition), and the other was published in 1584 (the later edition).
In this paper, we focused on the
yao-dao “腰刀” and the
chang-dao “長刀” in those two editions of the book. The conclusions of our study are :
1. The
yao-dao in the earlier edition has some special features that were adopted from the Japanese sword such as a single edge, a long thin edge, and an edge that is longer than the hilt, and a slightly curved edge. The
yao-dao was used with a shield made of cane in the earlier edition of
Ji-Xiao-Xin-Shu. In the traditional Chinese military idea, a sword was used with a wooden shield, and both the sword and shield were very heavy. The
yao-dao and a shield made from cane were lighter than the traditional Chinese swords and shields, therefore, these new weapons replaced the old ones. Through this process, some features of the Japanese sword were accepted in the earlier edition of
Ji-Xiao-Xin-Shu.
2. In the later edition of
Ji-Xiao-Xin-Shu, the
yao-dao and the
chang-dao were described. There was an explanation about how to make the
yao-dao, and some special features that came from the Japanese sword were described in the explanations. While both the
yao-dao and the
chang-dao have special features that come from Japanese sword, they are distinguished from each other by the total length of the sword with the
chang-dao being longer than the
yao-dao. The
yao-dao was used with a shield made from cane, and the
chang-dao was used with a rifle in the later edition of
Ji-Xiao-Xin-Shu. In the earlier edition of
Ji-Xiao-Xin-Shu, the
chang-dao and rifle were also described, however, there were no explanations in detail. In addition, there was no guidance given on how to use the
chang-dao with a rifle. In the later edition of
Ji-Xiao-Xin-Shu, the special features of the Japanese sword were accepted through the military idea such as using the
chang-dao with a rifle.
