In one anecdote recorded in the "Kōyō Gunkan", Bokuden was challenged by a mannerless ruffian. When asked about his style, Bokuden replied that he studied the "Style of No Sword". The ruffian laughed and insultingly challenged Bokuden to fight him without a sword. Bokuden then agreed to fight the man without his sword but suggested they row out to a nearby island on Lake Biwa to avoid disturbing others. The ruffian agreed, but when he jumped from the boat to the shore of the island, drawing his blade, Bokuden pushed the boat back out, leaving the ruffian stranded on the island. Bokuden explained: "This is my no-sword school". Bruce Lee was so fond of this story that in "Enter the Dragon (1973)" he teaches a bully a lesson about "Fighting without Fighting" when he offers to leave a junk and sail to an island.
