▪️ Musashi Daijo Korekazu
Hello, world! Thank you for checking our daily posts. Today, we would like to introduce another renowned maker.
Musashi Daijo Korekazu (武蔵大掾是一) was active during the early Edo period (1648-1673). The maker’s name Korekazu lasted seven generations. He belonged to the Edo Ishido school, which flourished during the Edo period. He played an essential role in spreading the fame of Edo Ishido school (江戸石堂派) nationwide.
The first-gen Korekazu was originally from Omi (近江, Today’s Shiga prefecture). It is said that he was a descendant of Ichimonji Sukemune(一文字助宗) from Bizen(Today’s Okayama prefecture). He moved to Edo and founded the Edo Ishido school at the beginning of the Edo period.
This school became one of the most popular ones in Edo city, Musashi Koku. And the third-gen Ishido Korekazu became an Okakaekaji for the Edo government in 1721, exclusively forging swords for the Tokugawa clan.
