"Honcho Bugei Shoden" (Short Stories of Japanese Masters of Martial Arts), written in 1716, lists many anecdotes of swordsmen including a tale about the duel on Ganryu-jima Island; the tale in question was told by Morikazu Juroemon NAKAMURA, a vassal of Tadahide MATSUDAIRA of the Amagasaki clan; according to that, like the description of "Numatake-ki," Musashi went to Funa-shima Island with many followers while Ganryu went by himself.
様々な武芸者の逸話を収集した『本朝武芸小伝』（1716年）にも巌流島決闘の伝説が記されており、松平忠栄の家臣中村守和（十郎右衛門）曰くと称して、『沼田家記』の記述と同様、単独渡島の巌流に対し武蔵側が多くの仲間と共に舟島に渡っている様子が語られている。
