Shimotsuki Kozaburo is a member of the Shimotsuki Family and a swordsmith who crafted the Great Grade Meito Wado Ichimonji and Enma. He was born in Wano Country, but illegally departed from there 55 years ago[1] and eventually settled down in what became Shimotsuki Village in the East Blue. There, he fathered a son named Koushirou, making him the grandfather of Koushirou's deceased daughter Kuina.[2]


All that has been seen of Kozaburo is a silhouetted profile of his head. He appears to have wild, spiky hair with a topknot, as well as a large nose. He wore a high-collared piece of clothing around his shoulders.[2]


Kozaburo appeared to be adventurous in his past, as he departed from Wano to adventure despite that being illegal. He was also caring, as he helped to save a village in the East Blue from bandits.[2]

Kozaburo forged the swords Wado Ichimonji and Enma, which were classified as Great Grade Meito.[1] 55 years ago, he illegally set out to sea. He eventually ended up in a village in the East Blue and helped save it from bandits. He fell in love with a woman while training the villagers in swordsmanship, and decided to stay in the village. 4 years later, he fathered a son named Koushirou.

He was still living in the village around a decade before the present day, as Roronoa Zoro once overheard him use the cry "Sunacchi" while training.[2][3]


  • Kozaburo's name has the same structure as his son Koushirou's, as both names begin with Kou and end with rou, and contain a number in the middle: zabu meaning three and shi meaning four.
