Usually the Kikuchi clan uses 'Maruni Narabi Takanoha' (in-line falcon's plumes inside a circle) or 'Maruni Chigai Takanoha' (crossing falcon's plumes inside a circle), but the family crest of the Tono Kikuchi clan is added the 'Hamon' (ripple) which refers to that the clan came from the sea, to the usual family crest, and shows as 'Maruni Narabi Takanohani Hamon' (in-line falcon's plumes with ripple inside a circle).
菊池氏は「丸に並び鷹の羽」もしくは「丸に違い鷹の羽」を用いることが多く、遠野菊池氏は通常の家紋に海路から入ったことを表す波紋が加えられ「丸に並び鷹の羽に波紋」で表す方が多いようだ。
