Our Partner: Nakajo Hardware – Forging Sanjo’s Soul into Steel


Nakajo Hardware Co., Ltd. is based in Sanjo, Niigata — a region with over 300 years of blacksmithing heritage. As both a distributor and brand curator, Nakajo connects Japan’s finest blades with chefs around the world, selecting tools that reflect precision, pride, and purpose.
The Brand: TAGAI
Their signature line, TAGAI, pays tribute to Sanjo’s forging legacy. Each blade is handcrafted by local blacksmiths who blend time-honored techniques with modern function — carrying forward the soul of Japanese craftsmanship.
The Visionary: Katsutoshi Nakajo
At the helm is Katsutoshi Nakajo, a passionate advocate for Sanjo artisanship. Known for his integrity and tireless work, he is both respected and affectionately called “a bit stubborn” by those who know him. His dedication has made him a key figure in promoting Sanjo's identity — both in Japan and on the world stage.
Our Collaboration
At Samurai Masterpieces, we are proud to partner with Nakajo Hardware. Many of our blades born in Sanjo are sourced through Nakajo’s trusted network — carrying forward stories forged in fire and refined by generations.
