Company Profile


Hokuichi workers are united in striving to be the customers’ go-to supplier.

Since its foundation in 1969, Hokuichi has been producing automotive components as its core product. Today, our automotive components are used in one in ten domestic vehicles, which is a milestone achievement. However, we are still not satisfied with what we have achieved.We will continue to take on new challenges and evolve as a leading supplier.
Hokuichi plans to apply its expertise to creating components used in various other fields, including medical devices, social infrastructure, and housing.

Employee development is high on our priority list. We are committed to developing an effective training system where each worker can pursue their technical learning.
The name “Hokuichi” means “Be the number one supplier in northern Japan”.
We envision that we will become the customers’-number-one-choice supplier. Our employees work hard every day to hear customers say,
“You can never go wrong with Hokuichi.”

Hokuichi continues to optimize its production system to provide competitive quality, cost, and lead-time.

Our job is to bring our customers a great deal of satisfaction through our products. To make this happen, we are focused on two things: enhancing automatization by installing the latest machines; and training employees. We strongly believe that these two elements need to go hand in hand to be a truly competitive supplier. We aim to be a manufacturer that can provide customers with safe and secure proposals and solutions.


We have built a unique production method consisting of three systems: manufacturing, quality, and control. We have improved production efficiency and stabilized quality.
