The subject Nobutaka 信高, a skilled sword craftsman of the Owari domain, primarily focused on creating robust Katana structures that met the increasing demands from brave Owari Samurais in full of martial spirit.
The 2nd generation NOBUTAKA was born in Keicho 8, (1603) as a legitimate child of 1st generation NOBUTAKA 慶遊信高 in Seki-kaji town Kiyosu Owari domain. He had moved to Seki-Kaji town Nagoya (now in Marunouchi 3 chome, Naka-ku, Nagoya) in 
Nagoya castle relocation , the 2nd month, Keicho 15 (1610). He obtained official district title "Hōki-no-kami" , in the 29th day, 8th month, Kanei 10 (1633) at 31 years old then had exclusively worked for Tokugawa Yoshinao 徳川義直 and the vassals of the Owari Tokugawas with as much as a one hundred koku stipend.
