What Yamato does

Yamato Denki Kogyo Kabushiki Kaisha (大和電機工業株式会社) is a Japanese functional plating manufacturer founded in 1944 and headquartered in Shimosuwa Town, Nagano Prefecture. The company operates a B2B job-shop model delivering electroplating and surface treatment for electronic substrates, semiconductor packages, micro connectors, and automotive components — including precious-metal plating, electroless UBM plating, lead-free RoHS-compliant processes, and proprietary spot/partial gold plating. Its technology stack extends into precision mechanical cutting and simultaneous 5-axis CNC machining, custom equipment design and fabrication, and analytical services (surface analysis via SEM/EDX/FIB, chemical analysis via ICP and titration).

Yamato's customer base is concentrated in automotive electronics (connectors, sensors, EV components such as DC/DC converters, battery terminals, and OCV/VVT parts), semiconductors, medical devices, and consumer electronics, with direct relationships to Japanese, European, and U.S. car makers and their Tier 1/2 suppliers. Quality and environmental systems (ISO 9001, ISO 14001, IATF 16949) underpin automotive qualification. The proprietary HLP高速レーザーメッキ™ high-speed laser plating technology, developed with Ibaraki University and M&M Laboratory, enables direct Au/Ag film formation on difficult-to-plate materials such as Ti-6Al-4V without traditional blast pretreatment and is protected by Trademark No. 5586531 and patent application 特願2017-168700.

The company operates a multi-entity group structure: the Nagano parent, wholly-owned Yamato Tec Co., Ltd. in Yamagata Prefecture (established April 1989), and wholly-owned Yamato Denki (Thailand) Co., Ltd. (acquired 100% in September 2018, renamed January 2019) operating three factories totaling 17,154 m² of land in Rojana Industrial Park, Ayutthaya Province. In October 2025, Yamato established ZUKU.tec合同会社 as a joint venture with Suwa Tokyo University of Science to commercialize university-developed new materials, combining academic research with the group's manufacturing capability. Headcount is approximately 420 in Japan (November 2024), 320-350 in Thailand, and 145 at Yamato Tec, with 91% new-graduate retention and 16.4-year average tenure. Distribution is direct enterprise sales via web inquiry forms and trade shows; revenue is generated through custom project quotes for plating, machining, and equipment manufacturing jobs.
