Mabuchi Motor Co., Ltd.: history, ownership, mission, how it works & makes money

From a modest start as Tokyo Science Industrial Co., Ltd. on January 18, 1954, Mabuchi Motor has grown into the world's leading small electric motor maker-producing about 1.4 billion units annually-and built a global footprint with 32 consolidated subsidiaries, 10 sales offices, 13 factories and 2 R&D centers; listed on the Tokyo Stock Exchange (6592), the company reported net sales of ¥196,212 million for FY2024 while profit attributable to owners fell to ¥12,831 million (down 33.9% year-on-year), a performance set against strategic moves like the 2024 acquisition of OKI Group's precision small motor business and the establishment of OKI M･E Co., Ltd., a workforce of 911 employees (6/30/2025) within a consolidated group of 17,678, ISO 9001 and ISO 14001 certifications, a 2015 stock split that raised shares outstanding from 37.875M to 70.927M, and a dominant market position-about 70% share in motors for automotive door mirrors, door locks and A/C dampers-driven by decentralized manufacturing (largely in China), continuous R&D, and a mission to deliver quieter, longer-lived motors while pursuing sustainability and a 2030 management plan focused on human capital and global expansion.

Mabuchi Motor Co., Ltd. (6592.T): How It Works

• Core products: brushed and brushless DC motors, coreless motors, gear motors and drive modules.
• Main end markets: automotive (including power mirrors, power seats, HVAC actuators), home appliances (vacuum cleaners, power tools, electric shavers), office equipment (printers, cameras), and industrial equipment.
• Competitive strengths: high-volume manufacturing scale, process control, miniaturization expertise, and global sales/aftermarket network.

• Manufacturing and selling small electric motors and assemblies to OEMs and tier suppliers across automotive, consumer electronics, appliances and industrial sectors.
• After-sales and spare part sales for installed motors, and custom engineering projects for specific customer applications.
• Growth via strategic acquisitions and technology licensing to expand product range and address higher-value segments.

• Acquisition impact: The 2024 purchase of OKI Group's precision small motor business is intended to broaden product offerings (precision/medical/industrial niches) and create new revenue streams through higher-margin, precision motor applications.
• Profitability challenge: Despite a nearly 10% sales increase to ¥196,212 million, profit attributable to owners fell 33.9% to ¥12,831 million-reflecting mix shifts, input-cost pressure, FX effects and investment in capacity/technology.
• Product application breadth: The diversity of end uses (power drills, vacuum cleaners, digital cameras, automotive actuators, office machinery) spreads commercial risk and provides multiple growth vectors as OEMs electrify and automate products.
• Innovation focus: Continued investment in miniaturization, brushless technologies and integrated drive modules aims to capture more of the global small-motor market and move into higher-value solutions.
