In
the 12th and 13th centuries, Japan developed into an aristocratic and
imperialist society. This is the time when Japan (called Edo before), had its
samurais. Samurais were related with middle and upper ranks of warriors trained
to become officers with unique techniques and strategies when it comes to
fighting (later known as bushido martial art). They were in service of their
clans or their lords. Zen Buddhism was also the religion of these trained
soldiers which furthered their work ethics and their principles of death and
killing.
