Sadao Araki
The Army and Navy were concerned that the number of swords extant were too few to accommodate the needs of the growing officer corps. With backing from the Household Ministry, the Army Ministry, and the Ministry of Culture, a swordsmithy (the , "Japan sword and forging society") was established on 8 July 1933. Kajiyama Yasutoku and Miyaguchi Yasuhiro were appointed as swordsmiths by Army Minister General Sadao Araki. The kanji was taken from the shrine and affixed with a character from their personal names () to form their sword names. Kotani Kenzo and his cousin Kajiyama Toshimichi were their uncle's assistants.
