Kohrai Gumi is a more advanced one layer Takadai braid.  It blends Plain Weave and Twill structures.  The appearance of the braid will be different depending on how these two structures are combined.  In this specific variation, Plain Weave is executed twice on each side, followed by two repetitions of 2-2 Twill on each side.  The literal translation of the name is “Light Will Come Braid.”
