Chiba Shūsaku Taira no Narimasa (千葉 周作 成政, 1793, Kese Village (now part of Kesennuma, Miyagi Prefecture), Japan – January 17, 1856) was the founder of the Hokushin Ittō-ryū Hyōhō (北辰一刀流兵法) and one of the last masters who was called a Kensei (sword saint). Most historians name him the greatest and strongest Samurai in history, not Miyamoto Musashi. This is because his life and duels are well documented and don't base on legends or on his self telled stories, like Musashis.
