Tadayoshi 1st had a lot of pupils and after the second had succeeded the family, many pupils helped him a lot and secured his prosperity. He succeeded to Oumi Daijo in July of Kanei 18 and he kept on making swords for 60 years. Tadahiro produced numerous swords, but among them, 2nd is really popular. He passed away at the age of 81, in Genroku 6. Mutsu Daijo Tadayoshi 3rd, Harima Daijo Tadakuni, Kawachi Daijo Masahiro, and Dewa Kami Yukihiro…There were lots of great pupils from his school. And he also got supported by Nabeshima
Domain and monopolized hollandaise iron, he made unique Jigane and he allowed its production only within his family. This blade is made right after his father passed away: around Kanei 13.
