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 in his family.
From Aoi Art: this work has approx. 3cm Suriage Machiokuri. The Nakago has gold inlaid Saidanmei. It is rare to find Hizento with Saidanmei so this is an importance piece. Suguha with deep Nioikuchi has changes. The edge is soft. The blade is wonderfully
made. Gold inlay has no omissions and beautifully done. Yamano Kauemon Nagahisa is a famous cutter for Saidanmei. We truly recommend this to you.
