Greetings from the president

As a specialized trading company responsible for providing components, we offer new value.

The origin of Sansei is a street stall set up in Akihabara after the war by founder Seiichi Adachi (who worked at Nakajima Aircraft Company). It has been over 60 years since Sansei became a corporation, and we have continued to provide components for many set manufacturers and EMS manufacturers, focused on connectors and switches, in a wide range of fields such as FA, robots, medical devices, and household appliances. In recent years, small lots and many kinds of manufacturing have become in demand in many industries. We are in an era when manufacturers must quickly and flexibly procure components on their own. Direct sales and e-commerce are proceeding throughout the entire world. However, we feel that in the electronic components industry, our role as as trading company is becoming much larger. Accepting this situation, our company is putting forth a new mid term management plan called “Reborn ~ Creating New Value” since 2021. It has 3 basic objectives: “improving customer satisfaction,” “expanding strategic stock,” and “building sales for high value added products.” We deeply understand customers’ business plans and manufacturing plans, and as a specialized company providing components, we will continue to strive as a group to offer new value.

President and Representative Director, Mitsutaka Mimura
