What 第一電材（株） does

第一電材株式会社 (Daiichi Denzai Co., Ltd., 'DID') is a privately held, independent Japanese trading company founded in 1968 and incorporated in 1969, specializing in electrical wires and cables. The company is headquartered in Chofu, Tokyo and operates through fourteen locations (ten domestic branches across Kanto, Tohoku, Chubu, Hokuriku, Kyushu, and Kansai, plus Hong Kong and two Shenzhen sites) and a wholly-owned manufacturing subsidiary, Daiichi Denzai Electronics Co., Ltd. With access to over 200 wire and cable manufacturers and a direct sales force of 'Professional Wireists' who undergo a roughly one-year logistics rotation before external selling, the company delivers proposal-based engineering to enterprise customers in semiconductor manufacturing equipment, medical devices, precision measurement, communications infrastructure, machine tools, and food machinery.

The technology stack centers on three product categories: custom-made products (robot cables, complex multicore cables, low-outgas cables, EtherCAT cables, custom connectors, flexible printed circuits); original DID-branded cables holding multi-jurisdictional certifications (FD/FDS, STO/TC(CE), UL2990 CE2S, UL2517 V2S, NEC CL3 2464); and suppliers' standard catalog items including thermocouples, heat-resistant cables, ultrafine coaxial cables, optical fiber, high-frequency coaxial, and machine vision cables. Through Daiichi Denzai Electronics, the group performs in-house processing (cutting, stripping, crimping, custom unit assembly) at six Japanese factories, with a dedicated quality control department concentrated at the Northern Kanto Branch given medical-equipment tolerance sensitivity.

The revenue model is transaction-based B2B distribution: DID purchases wires, cables, connectors, IC sockets, and electronic materials from manufacturers, adds a margin through pricing for value, and resells to industrial customers, while also generating revenue from processing and assembly services via its group factories. Pricing is quote-based, varying by customer, volume, specification, and processing required — no public list pricing exists. Distribution operates direct-to-enterprise from a Japan-centric base with Greater China regional support. Representative Director Takuya Umezawa (in role since 2005) has driven the company's 'second founding era,' with disclosed revenue of JPY 10 billion achieved in 2021 and stated growth targets of JPY 50 billion within three years and JPY 100 billion by the 60th fiscal year.
