1. In kendo, "Dao" is a kind of weapon, such as "Taidao"; In addition, there are more weapons and knives than swords in Japanese legends, such as the demon knife "Murakami". Therefore, "sword" in Japanese generally refers to a specific weapon, and the scope of "sword" in Bushido is larger than "knife".

2. The Roman word "kendo" in Japanese is pronounced as "kendo" (which can be pronounced according to the English International Phonetic Alphabet), and its pronunciation is similar to that in Chinese, which may be a translation habit.
