Umezawa

What Umezawa does

Umezawa (梅沢無線電機株式会社) is a privately held Japanese electronics company headquartered in Tokyo that designs, manufactures, and sells proprietary embedded computer modules and electronic components for industrial customers. The company operates two own-brand product lines: the HT series of PC/104 bus CPU and I/O modules (including CPU modules HT1010, HT1030, HT1040, and HT1070, plus more than 15 expansion modules covering digital I/O, serial communication, Ethernet, GPIB, motion control, and storage) and the UEC series of Z80- and 68000-based card-sized CPU boards (UEC-Z02A, Z04B, Z07, Z77A, Z77G, and UEC-68K). The HT9177 bus adapter allows UEC Z80 boards to interoperate with the HT I/O ecosystem, and the company also offers embedded solutions and surveillance camera solutions as service lines.

The company has been a 100% wholly-owned subsidiary of Takebishi Corporation (株式会社たけびし), an electrical and electronics technology trading company, since April 1, 2020. It distributes through three domestic sales offices in Tokyo, Sendai, and Sapporo, a direct e-commerce web shop, and joint trade show appearances with its parent. End customers are Japanese industrial IoT and embedded systems integrators, as well as electronics manufacturers building custom industrial computing platforms; specific named end customers are not disclosed. The company was an early entrant in card-sized embedded microcomputer boards, having pioneered that form factor in 1987 (Showa 62), and emphasizes long product life cycles, in-house firmware development, and vertically integrated design from circuit and PCB layout through enclosure design.

The business model is hardware sales of proprietary CPU and I/O modules, supplemented by contract design services and solution offerings, with publicly listed pricing on a small set of developer tools (e.g., UEC-MONZ80 and UEC-MONZ77 monitor programs at ¥4,000 each excluding tax). Revenue, headcount, and ownership-level financials are not publicly disclosed. Recent operational actions include two Tokyo headquarters relocations (December 2021 and November 2024), the closure of the Sapporo retail storefront in June 2025, and the August 2025 consolidation of the Technical Promotion Department within the Sapporo office.

Core offering

Umezawa designs, develops, and manufactures proprietary embedded computer modules and industrial electronic components in Japan. The portfolio centers on two own-brand product families — HT series PC/104-bus CPU and I/O expansion modules and UEC series Z80/68000-core card-sized CPU boards — sold to industrial customers for IoT infrastructure, factory automation, and machine-control applications. The company also provides embedded design services covering circuit/PCB design, firmware development, and contract manufacturing.

Product overview

Umezawa (梅沢無線電機株式会社) develops and sells embedded computer modules, electronic components, and industrial computing systems. The product portfolio consists of two main own-brand lines: HT series (PC/104 bus modules) and UEC series (Z80-6800 core CPU boards), plus contract design and manufacturing services. The HT series includes four CPU module models (HT1010/DOS, HT1030/H8, HT1040/H8 with TCP/IP+USB, HT1070/Armadillo-Linux) that serve as the computing core, accompanied by 15+ expansion I/O modules covering digital I/O (HT2010-HT2070), serial communication (HT3080), programmable I/O (HT3070), Ethernet (HT3060), motion control (HT3030, HT3035), GPIB (HT3020), and storage (HT3040, HT3010-F00). The UEC series comprises five Z80/68000 CPU board models (UEC-Z02A, Z04B, Z07, Z77A, Z77G) ranging from basic to Flash-equipped variants, with the HT9177 bus adapter enabling HT series expansion modules to be used with UEC boards. The company also offers embedded solutions and surveillance camera solutions as service offerings.
