MINEBEA MITSUMI

Minebea Mitsumi helps OEMs turn tough constraints — size, power, speed, reliability — into advantages. Through an integration approach that blends precision mechanics with electronics and software, the company delivers system-level solutions for fast-moving markets such as EVs, AI, XR, and renewable energy. Its technology roadmap targets the “four highs” (high voltage, current, frequency, and speed) while vertically integrated “mother” factories and automated lines translate R&D into stable, high-precision mass production. A diversified global footprint — spanning 28 countries, 125 production and R&D bases, and 101 sales offices — adds resilience and supply assurance. Guided by a clear philosophy — providing better products, at a faster speed, in larger numbers, at a lower cost, and by smarter means — Minebea Mitsumi connects performance with progress. The company’s QCDESS strategy puts eco-efficiency at the center, with concrete goals: raise Green Products to 90% of sales, avoid around 4.0 million tons of CO₂ through product use, cut total greenhouse-gas emissions by 30%, and continuously strengthen the system for safe, mass, and stable supply of ultra-precision components. Talent development, diversity, and responsible procurement are embedded so that growth and sustainability advance together. For customers, this means dependable quality and delivery even in volatile conditions. Minebea Mitsumi backs its promises with business-continuity planning, global “local-for-local” production, disciplined financial management, and ongoing digital transformation — using AI and data to raise efficiency and responsiveness across the value chain. The result is a partner built for precision today and a sustainable, low-carbon future tomorrow.

Company History

Founded in 1951 as Japan’s first specialist in miniature ball bearings, Minebea Mitsumi (originally Minebea Co.) began by perfecting precision bearings for demanding applications. In subsequent decades, the company pursued an aggressive growth strategy, earning the nickname “Original M&A Company” as it expanded its capabilities through acquisitions in Japan and overseas. This strategy transformed Minebea from a niche bearing producer into a comprehensive precision parts manufacturer serving industries ranging from aerospace and automotive to information technology and consumer electronics.

A milestone came in 2017 when Minebea merged with Mitsumi Electric, uniting Minebea’s expertise in micromechanical components with Mitsumi’s strengths in electronic devices. The newly named MinebeaMitsumi fused ultra-precision machining technology with advanced electronics technology – a combination that paved the way for a greatly expanded product lineup and integration of capabilities. Today, the company’s history of innovation and strategic integration continues as it evolves to meet the needs of the IoT era and beyond, while staying true to its precision-engineering roots.

Production and Manufacturing

At the heart of MinebeaMitsumi’s manufacturing prowess is an ultra-precision machining foundation coupled with a vertically-integrated production system. The company’s production processes are vertically integrated from product development and component fabrication all the way through assembly, ensuring complete control over quality and performance. MinebeaMitsumi’s “mother” factories in Japan develop state-of-the-art manufacturing techniques (such as proprietary automatic assembly lines) which are then deployed across mass-production plants worldwide. This approach guarantees high precision on a mass scale – balancing micro-level accuracy with efficient large-scale output. Furthermore, by organically linking its R&D hubs with 125 production bases across Asia, Europe, and the Americas, MinebeaMitsumi maintains a robust global supply network. It can quickly deliver precision components to customers around the world while diversifying risk across its multiple production sites. In short, the company’s strength in ultra-precision machining, combined with vertically integrated and globally distributed manufacturing, enables a stable supply of top-quality components at any volume.
