History-”Sanjo as a Town of Blacksmith” & “Hocho-Kobo Tadafusa”

Sanjo is well-known as “a town of blacksmith” as well as a town of hardware production highly praised by the people inside and outside Japan. Ikarashi River is located in center of Sanjo. Once upon a time, the river, which is called “Abare-Gawa(river)”, was well-known for having been flooded again and again from old times. During three years from the second year of Kanei era(1625), Otani Seibei, who was served as a governor’s officer of Edo-Bakufu(the government in Edo era), came to give aid to poor peasants at the area because of often deluges of the Igarashi River. He also invited blacksmiths to teach them how to make Japanese hand-forged nails for their side business.

In the first year of Kanbun era(1661), new forging techniques was introduced from Aizu area to Sanjo. Thanks to them, the blacksmiths in Sanjo were getting to be specialized while the production that they made became divergent from nails to sickles, saws, and kitchen knives.

With increase in number of the specialized blacksmiths, marchants gradually appeared to deal with hardware products made in Sanjo. They used rivers such as Igarashi River and Shinano River(the longest river in Japan) to expand their business area. As a result of that, they also contributed to make Sanjo well-known as “a town of hardware products” throughout the country.

In these forging histories in Sanjo, the founder, Sone Torasaburo started  Tadafusa from nothing since the 23rd year of Showa era(1948). He made various kinds of knives such as sickles, short swords and kitchen knives by use of his forging techniques from his apprenticeship to make hand-forged metal scales. He gradually started to be specialized to make fishing knives and then also address to create kitchen knives for home and professional use and special knives for Soba up to today. Since the company’s foundation, we effort to generate “real good products” to our customers by hand through every single process to make each knife with our enthusiasm.
