What Meidensha does

Meidensha Corporation (株式会社明電舎, TYO:6508) is a Tokyo-headquartered, publicly traded industrial manufacturer and engineering services provider founded in 1897 and formally incorporated in 1917, employing approximately 10,082 people on a consolidated basis as of March 31, 2026. The company operates across four reporting segments: Power Infrastructure Systems (transformers, switchgears, transmission and distribution equipment for utilities), Water Infrastructure Systems (water and wastewater treatment including proprietary ceramic flat membrane units), Industrial Electronics and Mobility (motors, inverters, EV/HEV drive units, and electronic components), and Field Engineering Services (maintenance, remote monitoring, and facility management for installed equipment). Technology differentiation rests on power electronics, ceramic membrane water treatment, electrochemical and water quality measurement instrumentation, and high-purity ozone gas generation systems for semiconductor ALD/MBE processes (Meiden Nano Process Innovation). Meidensha sells primarily via direct enterprise field sales in Japan and through wholly-owned group companies across Asia, Europe, and North America, with a 27.9% overseas sales ratio and operations spanning 65+ countries; FY2025 consolidated net sales were ¥326.1 billion. Recent product launches include the HJ-Neo battery charge/discharge system (2023-09), HOE-1000M2 high-precision gas measurement instrument (2024-07), and ongoing commercialization of Pure Ozone Generator and OER surface treatment systems for semiconductor manufacturing customers.
