What Tanaka Denki Kogyo does

Tanaka Denki Kogyo (田中電機工業株式会社) is a privately held, family-controlled industrial technology and IT services company founded in 1929 in Hiroshima, Japan. The company operates four specialized business divisions: the EC (Electric Control) Division designs and manufactures electrical control panels, instrumentation panels, high-voltage receiving panels, and power device durability testing equipment; the IT Division provides software design and development, IT equipment sales and maintenance, and IT consulting, with a strategic IBM Japan partnership recognized via the 2021 IBM Japan Excellence Award and 2022 consecutive-year IBM Business Partner recognition; the Solution Division delivers comprehensive automation technology solutions; and the MS Division provides manufacturing maintenance services.

The company's revenue model is diversified across hardware sales (control panels, electronic substrates), IT services and software, managed services (maintenance via MS Division), and consumer products (electrolytic hydrogen water ionizers distributed under agency arrangement with Japan Trim, and hydrogen-water-cultivated Aki Komachi strawberries). Go-to-market is sales-led through dedicated division-level field sales teams targeting Japanese manufacturing enterprises, government/education customers (Hiroshima Prefecture/City school computer procurement), and consumer segments. Distribution is domestic-only across multiple Hiroshima-region offices and factories (Hiroshima City, Higashihiroshima, Akitakata, Shobara, Fukuyama).
