Our strengths
A thorough commitment to on-site operations. Leveraging our expertise in the steel and rare metals sectors, and our strong international network centered in Japan, Mexico, and India, we address our customers' challenges from procurement to quality control and trade operations, always with a practical, on-the-ground perspective.
Message from the President
“The Power to Sell Begins with the Power to Buy.”
For Japanese manufacturers to remain competitive in the global market, we believe it is essential not only to ensure a stable supply of high-quality raw materials from around the world to Japan, but also to bring Japanese products and technologies to global markets.
Drawing on our experience at Metal One, a leading steel trading company, we take into account global developments and international business practices, as well as tariffs and regional content requirements, to build optimal supply chains and support stable manufacturing operations.
At YAMAZAKI Co., Ltd., we also strive to foster mutual understanding between suppliers and customers. By working together on technical specifications and quality requirements and pursuing continuous improvement, we aim to build long-term relationships based on trust.
In August 2026, we established the Mexican Chamber of Commerce in Japan. By connecting Japanese and Mexican companies, we help create new business opportunities and contribute to the sustainable development of economic relations between Japan and Mexico.
