What FEC does

FEC Co., Ltd. (株式会社エフイーシー) is a privately-held Japanese systems integrator and software developer headquartered in Fukushima City, Fukushima Prefecture, founded in April 1980. The company operates across two principal lines: traditional enterprise IT services — custom system development, ERP and business software resale, hardware supply, and network design/construction — and a smaller but technically distinctive proprietary IoT product business built around the I2C Interface Driver and IoT Trial Kit. Its customers span manufacturing (automotive, semiconductor, rubber), educational institutions, local government, healthcare providers, retail/wholesale, and agricultural cooperatives, with activity concentrated in Fukushima Prefecture and the broader Tohoku region of Japan.

FEC's core proprietary technology is the I2C Interface Driver, a DLL-based API that exposes I2C sensor register operations as simple property reads and writes in VB.NET and C#, enabling business application developers to build IoT systems on Raspberry Pi 3 with Windows 10 IoT Core without embedded programming expertise. The I2C Driver supports 12 device types including temperature, humidity, barometric pressure, acceleration, gyro, light, color, CO2/VOC, and motor controllers, with calibration processing handled internally (e.g., 20-bit BME280 correction). The company complements this software with the IoT Trial Kit, a pre-integrated hardware platform combining 12+ sensor modules, USB adapters, ARM Cortex-A53 network controllers, splitters, and data logger software, protected by proprietary multi-layer circuits (LC filters, 6V+ ESD protection, 25kV/μs isolation). As an authorized dealer and solution partner, FEC also resells and implements Microsoft (Gold Certified Partner since 2006), Oracle, OBC奉行 ERP, Fujitsu FM Network, Grape City Leyser school accounting, and はぐくむ保育 nursery care systems, plus its own Equipment Maintenance Management, Production Management, and Asset Management software products.

Revenue is generated through a mix of professional services fees for custom system development, perpetual software licensing for the I2C Driver (¥71,760 standard single license; ¥95,760 site license), hardware unit sales for IoT sensors and trial kits (¥39,800–¥59,800 per sensor module), and recurring or maintenance contracts on third-party ERP and business software resale. Distribution is direct-to-enterprise via field sales and system engineers in Fukushima and Tohoku, supplemented by email-driven self-serve ordering for IoT products and a partner/reseller channel for Microsoft, Fujitsu, OBC, Grape City, Ricoh, and Xerox offerings. FEC holds a wholly-owned subsidiary in Xi'an, China (established 1988) and a related international trading company (established 1994), though day-to-day revenue remains overwhelmingly domestic.

Scale indicators4 records

Recent moves10 records

Expansion highlights3 records

Broad incumbents

• NS Solutions Corporation: Japanese systems integrator spun out of Nippon Steel, serving manufacturing, finance, and public sector with custom systems and IT consulting. Comparable to FEC's vertical (manufacturing-heavy) systems integration focus and ERP-style application development.
• CTC (ITOCHU Techno-Solutions): Major Japanese IT services company providing systems integration, network solutions, and cloud services. Comparable to FEC's enterprise IT solutions and network design business, though at vastly greater scale and geographic reach; competes for the same type of mid-market enterprise customers.
• Fuji Soft Incorporated: Major Japanese systems integrator providing embedded software, IT solutions, and BPO services. Comparable to FEC's combined IT services + embedded/IoT capabilities but operates at much larger scale across Japan, representing a competitor for enterprise customers and a potential acquirer.
• Yokogawa Electric Corporation: Global industrial automation and process control company with deep sensor and instrumentation portfolio. FEC's earliest IoT work was developed with Yokogawa; they represent the industrial incumbent against whose installed base FEC positions its I2C trial kit for factory applications.

Emerging players

• Idein Inc. Japanese edge-AI/IoT startup whose actcast platform enables sensor data collection and AI inference on edge devices including Raspberry Pi. Comparable to FEC in targeting Raspberry Pi-based IoT deployments for Japanese enterprises, with overlapping customer use cases (factory, retail, facility monitoring).
• KERS Co., Ltd. (M5Stack Japan distributor): Japanese distributor and integrator for M5Stack and other IoT development platforms. Comparable to FEC's IoT trial kit concept — bundled sensor modules and developer-friendly APIs — though targeting a broader hobbyist/maker audience rather than FEC's enterprise vertical.

Others

• OBC (Ōbunsha Business Consultants): Japanese ERP/accounting software vendor whose 奉行シリーズ FEC resells and customizes. Listed here as a partner/upstream vendor relationship rather than competitor; understanding OBC's roadmap and partner program is critical to FEC's ERP business.

Direct peers

• Braveridge: Japanese IoT hardware platform company that designs and manufactures sensor modules, BLE/Wi-Fi modules, and end-to-end IoT solutions for Japanese enterprises. Comparable to FEC's I2C/IoT product line in providing integrated sensor-to-cloud platforms targeting Japanese manufacturers and infrastructure operators.
• Future Corporation: Japanese IT consulting and systems integration firm serving manufacturing, distribution, and financial services. Comparable to FEC's custom systems development business for mid-market Japanese enterprises, though at substantially larger scale (multiple thousands of employees) and broader geographic coverage.
• Switch Science: Japanese electronics retailer/distributor specializing in IoT development boards, sensors, and maker-focused components. Directly comparable as a seller of sensor kits and developer tools in Japan, though with a different channel model (e-commerce vs. direct inquiry) and broader maker/hobbyist audience.
