Connect people and society
DAIICHI DENSHI SANGYO CO.,LTD.

Company Introduction

Greetings

We will continue to create and realize dreams together with you.

In 2025, our company proudly celebrated the fiftieth anniversary of its founding. Over this long journey, we have been able to carry forward our business thanks to the support of so many people—our valued clients, suppliers, local communities, employees who have dedicated themselves to the development and continuity of our business, and their families. To all of you, we extend our heartfelt gratitude.

During this time, we have expanded our bases in Japan (Amagasaki City and Akashi City, Hyogo Prefecture), as well as in China, Hong Kong, Laos, and Thailand. Through daily efforts and trial and error, we have strived to become a company that can serve each country and region, embodying our corporate mission of “connecting people and society.” This is not a goal with an end point. The more we continue and pursue it, the more we realize that we must adapt to changes in society and reflect on our own actions. We aspire to be a group that constantly examines our behavior and thinking, and that makes honest, sincere efforts toward endless goals. We want to be a group that spares no effort in creating dreams and realizing those dreams together with all who support us.

Our current main business is the processing and manufacture of wiring harnesses, as well as the sale of various electronic materials and equipment. These products may not often be seen directly by many people, as they are usually small components within our customers’ final products. Yet without them, those products could not fully demonstrate their performance and functions. Though small and unobtrusive, they play an important role in supporting everyday life. With quiet pride, we will continue working with our employees to be a company that serves you more widely and deeply.

Furthermore, we will never forget the spirit of challenge that sustained us when we began as a small trading company of electronic materials and equipment. We will continue to embrace flexibility and boldness as we explore new business fields and new markets, including overseas. With this spirit, we aim for sustainable growth together with you.
As we look ahead to the next fifty years, we sincerely ask for your continued support and guidance.
