In Japan, I learn it as one of the classes of the schools.
kendo is the succession of the Bushido.
It is over in opening etiquette in etiquette entirely.

Korean Kumudo dojo pretends to be Japanese Kendo in U.S.A., and please be careful now because I gather students.
Kumudo copied Japanese Kendo in Korea in 1980, and it was made.
