Tokyo Head Office
The Central Hub Where All Roles Come TogetherLocated in Chofu City, Tokyo, this is the core of DID. The wide variety of products handled—often in small quantities and many variations—makes it an ideal environment for employees across all roles to build broad expertise. Another distinctive feature is that all departments, including sales, logistics, and general affairs, work together under one roof.
Northern Kanto Branch
At the Forefront of the Electronics IndustryServing many customers in cutting-edge electronics industries, particularly medical equipment manufacturers. Due to the high demand for processed products where quality variations can easily occur, this branch is the only location within the group equipped with a dedicated quality control department.
Yamanashi Branch
"Team Yamanashi" — Working as One with the FactoryThis branch is paired with the only factory in the group capable of manufacturing large-scale processed products known as "Thick Cables" items. The branch and factory operate as one team, working hand in hand to support sales activities—making this location a prime example of DID's strengths.
Tohoku Branch
Business Expansion Driven by Growing Semiconductor DemandWith major semiconductor manufacturing equipment companies as customers, this branch has expanded rapidly by riding the wave of increasing semiconductor demand. In 2022, both the branch and the adjacent Daiichi Denzai Electronics facility moved into newly constructed buildings, making it one of the most dynamic locations in the group.
Hokuriku Branch
"Everyone Is Involved in Manufacturing"Equipped with a small-scale processing facility within the branch, this location delivers products tailored to local customer needs through a one-stop process. Guided by the philosophy of "everyone participates in manufacturing," the team operates as a tight-knit, highly skilled unit supporting craftsmanship with efficiency.
