In order to study medicine Eguchi Tōan went to old Yoshida Ichian’s place in the Banchō area of Edo. At that time, there was in the neighborhood a teacher of swordsmanship, to whom he used to go for training from time to time. There was a rōnin pupil there who one day came up to Tōan and said as a parting remark, “I am now going to realize a long-cherished ambition, one I have had for many years. I am informing you of this because you have always been friendly to me.” Then he walked away. Tōan felt uneasy about this, and when he followed him, he could see a man wearing a braided hat coming from the opposite direction.
Now the sword teacher was about eight or ten yards ahead of the rōnin, and in passing by the man with the hat he soundly struck the man’s scabbard with his own. When the man looked around, the rōnin knocked off the man’s hat and announced in a loud voice that his purpose was revenge. With the man’s attention being distracted by the confusion, he was easily cut down. A tremendous amount of congratulations came from the nearby mansions and townhouses. It is said that they even brought out money for him. This was a favorite story of Tōan’s.
