Akai-shū

The Akai-shū (赤衆, literally "Red Company" or "Red Group") were elite units of mounted samurai within the Takeda clan's army during Japan's Sengoku period (roughly 1467-1615). These units were distinguished by their red-lacquered armor and weaponry, designed to create a visually intimidating and cohesive force on the battlefield. Led by highly skilled and trusted commanders, the Akai-shū were known for their aggressive tactics and effectiveness in breaking enemy lines or delivering decisive blows.

The most famous Akai-shū was likely led by Takeda Shingen's retainer, Yamagata Masakage. His unit was particularly renowned for its ferocity and battlefield prowess. While the exact number and composition of Akai-shū units might have varied throughout the Takeda clan's history and under different commanders, the consistent use of red armor served as a clear identifier and a symbol of their elite status.

The use of uniform colors and distinctive equipment was a common tactic among Sengoku period armies to improve unit cohesion, distinguish friend from foe, and instill a sense of identity and morale within the ranks. The Akai-shū represents a notable example of this practice, contributing significantly to the Takeda clan's military reputation.
