Why it matters
Tsubame-Sanjo refers to the neighboring cities of Tsubame (燕市) and Sanjo (三条市) in Niigata Prefecture, which together form one of Japan’s most important metalworking regions. The area’s smithing history begins in the early Edo period, when farmers took up nail-making as winter work during the heavy Niigata snowfalls. Over centuries, that sideline grew into a full industrial cluster covering knives, tools, kitchen utensils, and stainless steel housewares.
Today the region is known worldwide for precision stainless steel products. Western-style kitchen knives from Tsubame-Sanjo compete directly with Seki and Sakai output. The local expertise in stainless steel processing, surface finishing, and precision grinding translates directly to scissor manufacturing.
Shear production
Tsubame-Sanjo’s direct scissor output is small compared to Seki. However, the region plays a meaningful role in the supply chain. Some scissor manufacturers source precision-ground steel blanks or sub-components from Tsubame-Sanjo workshops. The area is also identified as the home of precision convex edge blade technology, a critical advancment in scissor manufacturing that enables the ultra-sharp cutting edges found in premium Japanese shears.
Several scissor brands either manufacture in or source components from the Tsubame-Sanjo region, though most do not advertise this as prominently as Seki-based manufacturers do.
Visiting the region
The Tsubame-Sanjo area has embraced industrial tourism. The annual Factory Festival (工場の祭典, Kojo no Saiten) opens dozens of metalworking workshops to the public. It is a good opportunity to see the kind of steel processing and finishing work that feeds into the broader Japanese scissor industry.
