By the commission Yoriyuki MATSUI, Karo (chief retainer) of the Hosokawa family (later Yoriyuki became the lord of Yatsushiro-jo Castle), Musashi made a wooden sword after the one which he had used in the duel at Ganryu-jima Island; the wooden sword still remains.
また、細川家家老で後に八代城主になった松井寄之の依頼により巌流島の試合で使用した木刀を模したと伝えられる武蔵自作の木刀が現在も残っている。
