ボウリング
Ten-pin bowling lanes are from the foul line to the center of the head pin (1-pin), with guide arrows (aiming targets) about from the foul line. The lane is wide and has 39 wooden boards, or is made of a synthetic material with the 39 "boards" simulated using marking lines. The approach has two sets of dots, respectively and behind the foul line, to help with foot placement.
