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.
