"The City of Blacksmith" History of Tsubamesanjo
The genealogy of Monozukuri of Niigata Prefecture Tsubamesanjo goes back to the Edo period. From the early Edo period, it prospered as a place to create "Wakaku (Wakigi)". 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.
When entering the Meiji period, the experts of Kage had increased rapidly. Along with that, merchants start to trade in hardware products, making use of rivers, "Blacksmith City, Tsubame Sanjo" will be known to the world.
