NIIGATA PREFECTURE, JAPAN - Media OutReach Newswire - 21 January 2026 - Located close to the heart of Niigata Prefecture, the Tsubame-Sanjo area is a traditional Japanese  mecca of craftsmanship with a 600-year history dating back to the Muromachi period, when metal casting first flourished here. It is about two hours from Tokyo by bullet train. Many products beloved both in Japan and around the world are born here, from kitchen knives and Western-style cutlery to tools and outdoor gear. To preserve the techniques behind these diverse products, the central region situated around Tsubame-Sanjo has established initiatives that include certifying highly skilled artisans as Niigata Ken-O Meisters. 

But Tsubame-Sanjo's appeal extends far beyond technical excellence. Here, a distinctly Japanese philosophy thrives among craftspeople who finish each product with the end user in mind, infusing their work with warmth and care. Take the knives from Hinoura Hamono Koubou, for example. This blacksmith workshop uses proprietary methods grounded in scientific research, achieving both exceptional edge retention and ease of use. Blades that fuse over a century of forging expertise with innovative thinking have earned acclaim both at home and abroad. Meanwhile, Gyokusendo, a copperware house with over 200 years of history, continues to practice tsuiki doki, the traditional art of hand-hammering copper plates into elegant vessels. These pieces, which marry the beauty of handcraft with functional design, have won admirers from around the world.

From Nails to Knives: The History and Evolution of Craftsmanship
Tsubame-Sanjo's metalworking tradition traces its origins to Japanese nail-making some 400 years ago. Frequent flooding from the Shinano and Igarashi rivers created strong demand for nails to rebuild structures in this region. These nails found use not only in homes, but also in shrines, temples, and ships. As they circulated widely, nail-making became one of the foundations of local metalworking. Over time, production expanded to farming implements such as hoes and shears, then to kitchen knives, Western-style tableware, and other everyday tools, the industry evolving with each era's needs. After the Meiji period, stainless steel cutlery and tool manufacturing took off. Today, the region boasts such a diverse concentration of metalworking expertise that locals say there's nothing that cannot be made. Tsubame City and Sanjo City are home to thousands of small- and medium-sized enterprises, each bringing its own distinctive techniques and designs to global markets. In these communities, a guiding philosophy endures: don't simply inherit tradition; move forward by improving it. While honoring time-tested techniques, local manufacturers embrace new materials and contemporary design, ensuring constant evolution.
