Mitsubishi Materials Corporation is shaping Japan’s industrial transformation through a century-and-a-half legacy of mining, metals, and materials innovation that now powers the global shift toward sustainability.
As one of the oldest members of the Mitsubishi Group, Mitsubishi Materials traces its origins to 1871, when Tsukumo Shokai — precursor to the Mitsubishi Group — ventured into mining, laying the foundation for a business that would become a cornerstone of Japan’s industrial development. “Our roots go back more than 150 years, and throughout that time, we have continued to evolve with society’s changing needs,” said President and CEO Tetsuya Tanaka.
Today, the company’s operations rest on four strategic domains: the Resource Circulation Business, which engages in copper smelting and recycling; the Advanced Products Business, producing copper-processed products and electronic materials; the Cemented Carbide Tools Business, supplying high-performance tools for automotive and aerospace machining; and the Renewable Energy Business, advancing geothermal and solar power projects.
Mitsubishi Materials continues to operate on a global scale while maintaining Japan’s long-standing reputation for precision, responsibility, and innovation. The company’s integrated supply chain — from resource extraction to high-value manufacturing — allows it to respond swiftly to shifts in global demand while supporting partners seeking stable, sustainable material solutions.
Circular Economy and Innovation
From its early days in mining, Mitsubishi Materials has evolved into a leader in circular resource management. The company focuses on recycling resources by extracting metals such as copper from used and discarded products, then reintroducing them into new production cycles. “Natural resources are limited,” Tanaka said. “Recycling used products, especially electronic circuit boards, which we call E-Scrap, is positioned as a core part of our future business.”
This circular approach defines the company’s long-term vision, expressed in Our Commitment: “For people, society and the earth, circulating resources for a sustainable future.” Mitsubishi Materials is pursuing innovation across diverse domains and actively seeking global partners to advance this mission — from recycling and scrap-processing firms to technology companies developing new reuse and refining solutions.
“We are open to all partnership formats,” Tanaka said. “Whether it is joint ventures, R&D collaboration, or recycling partnerships, we want to work with companies that share our commitment to circulation and sustainability.”
The company also foresees strong opportunities in North America and Europe, where locally rooted recycling and resource recovery are advancing amid strengthened resource management across countries and regions. Mitsubishi Materials aims to build a resilient value chain by localizing its resource recycling business in North America and Europe.
Copper, AI, and the Future of Materials
“Copper is indispensable for the future,” Tanaka said. “As AI and electronic devices expand worldwide, demand for our materials will continue to grow — and so will our business.” Looking ahead, the global expansion of artificial intelligence and data centers will drive soaring demand for copper, a critical component in power and electronic infrastructure. In these circumstances, Mitsubishi Materials identifies major growth potential in developing circular frameworks for metal resources and expanding the scope, regions, and scale of operations.
At the same time, stricter resource management in regions such as Europe and the United States is reshaping global trade in recyclable materials. Rather than relying on imports of waste for processing, Mitsubishi Materials plans to establish local recycling bases abroad, working closely with partners to build new circular ecosystems within regional markets. This localized, sustainable model positions the company at the forefront of Japan’s drive to achieve net-zero industrial growth.
With its long history, diversified business base, and forward-looking environmental strategy, Mitsubishi Materials represents the new face of Japan’s industrial strength, one grounded in both tradition and transformation. “As a company, we aim to circulate resources for the betterment of society,” Tanaka said. “Through more than 150 years of history and innovation, we will continue contributing to a sustainable global economy.”
