Rei position

Two short lines of tape mark the positions in the center of the contest area where the two contestants stand to perform their "Rei" (bows) at the beginning and end of a contest. The two lines are approx. 5cm wide, 30cm. long, and are approx. 3.64m apart. One of the lines is red, and the other is white. Viewed facing the front, the red line is on the right, and the white line is on the left.
