This period saw the transformation of armor from the bulky, ornate "ō-yoroi" to the lighter, more flexible Tosei-gusoku.

The evolution of Tosei-gusoku was not merely a product of necessity but also reflected the changing societal ideals and the aesthetic sensibilities of the samurai class. The meticulous craftsmanship and elaborate embellishments on these armors were emblematic of a warrior's status, courage, and honor.
