Follow this link to an excellent response by Karl Friday to two questions posed by Scott R. Brown;

“1) Did the Bushido code, whether written out or not, exist as a concept in historical Japan?

2) Was the Bushido code used as a means to foster yamatodamashii in the soldiery during WW II?”

This should be of interest to anyone who has practiced any form of the bugei.
