In the early days of the Kanonaga period, due to the repeated flooding of the Igamasagawa River flowing through the center of the Sanjo town, farmers have difficulty making a living by agriculture alone. Therefore, by inviting craftsmen of Japanese nail making from Edo and teaching farmers their manufacturing technology, production of Japanese nails will begin in this area. Then a new smithing technology is transmitted, and products are changed from Japanese nails to sickles and kitchen knife, etc. At the same time, blacksmiths who inherited the technique of tradition are nurtured, and blacksmiths started as farmers' side jobs in the era of Japanese nail will also be established as professional smiths.
