Treasure Knot Waterfall was where an Akodo samurai-ko was courted by a Matsu samurai. The maiden gave him a knot, telling him that when he could untie the knot, he would win her love. The Matsu took one look at the knot and sliced it with his wakizashi. The maiden took the rash act as an insult and one of the greatest Akodo/Matsu rivalries began.
