A small cloth called 'katano hira hira' (flaps on the shoulders) is attached to the back of banryo collar (perhaps, the cloth is a surplus made when the collar was cut out) and semamori nui (back sewn as a charm) is made from the cloth.
盤領だが背面に「肩のひらひら」という小さな裂がつけられ（おそらく襟をあけるときに出た生地であろう）、そこから背守り縫いを施している。
