Support for small lot production of high-pressure harnesses (mass production and prototypes)
Over 20 years of experience as an independent wire harness specialized factory! We handle everything from prototypes of high-voltage harnesses for electric vehicles to small and medium lot mass production.
We are engaged in mass production (including prototypes) of various harnesses needed for electrification, ranging from high-voltage and strong electrical systems for automotive and industrial use to signal systems. We can accommodate prototypes even when the drawings are not finalized during the development stage, and we can handle medium-lot mass production at our domestic factory. It is also possible to procure specified connectors (providing end-user information to the connector manufacturer is necessary). *We can also accept supplied parts. In prototypes, we manufacture harnesses using the latest connectors upon requests from the research and development departments of automotive manufacturers and parts manufacturers, and we can also accommodate new connectors. In mass production, we have numerous achievements, including harnesses for car air conditioning, fuel pump systems, main harnesses for snow removal machines and riding lawn mowers, as well as onboard chargers for EVs and drive lithium batteries. We have extensive mass production experience, ranging from crimping, soldering, and shielded cables to small lead wire processing and main harnesses with over 300 circuits. We own more than 500 applicators, primarily for automotive use.

Company information
Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
