  • Miyoshi Nagamachi was born as the first children of Miyoshi Nagamasa(三善長政). After his father passed away, his uncle Masatoshi taught him sword making instead.
  • His original smith name was Miyoshi Michinaga(三善道長), but when he received the ZURYOUMEI(受領名) of Mutsu-daijo(陸奥 大掾),  his smith name was registered as Nagamichi(長道) by mistake, but he adopted that name and started using it from then.
  • His style was largely influenced by Kotetsu, so that Nagamichi was also called as Aizu Kotetsu.
  • He was known for making a sword with high-cutting ability. In collaboration with a sword tester, Yamano Hisahide(山野久英), Miyoshi Nagamichi succeeded in making a very sharp sword. A few of his swords exceed even those of Kotetsu. And he was among the best swordsmiths in the record of sword sharpness, called Kokon Kaji Biko(古今鍛冶備考) written by Yamada Asaemon(山田浅右衛門).
