High-pressure harness, small lot production of high-voltage harnesses for vehicles *Prototype available.
High-voltage harnesses for electrified vehicles and agricultural machinery available for mass production in small lots! As an independent company, we work with any manufacturer! Over 20 years of experience.
We are engaged in mass production (including prototypes) of various harnesses, from high-voltage harnesses in orange needed for vehicle and agricultural machinery electrification to signal systems. We can accommodate prototypes even when the development stage drawings are not finalized, and we can handle small to medium lot mass production at our domestic factory (with the latest dedicated equipment already introduced in the summer of 2024). We can also provide specified connectors (it will be necessary to provide end-user information to the connector manufacturer). *It is acceptable to supply parts. We can support mixed high-voltage harnesses where one side has connector A and the other side has connector B. In prototypes, we also manufacture harnesses using the latest connectors at the request of research and development departments from automobile manufacturers and parts manufacturers, and we can accommodate new connectors as well. 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 lithium batteries for drive systems. 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 about 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.
