What Tatsuta does

TATSUTA Electric Wire & Cable Co., Ltd. is a Japan-based diversified industrial manufacturer founded in 1945, publicly listed on the Tokyo Stock Exchange (TSE: 5816) and operating as part of the JX Advanced Metals Group. The company operates seven business segments — infrastructure wire, industrial equipment wire, functional film, functional paste, fine wire, sensor & medical, and environmental analysis — and holds what it describes as "overwhelming global market share" in its functional films business. Its three product pillars are: electric wires and cables (industrial equipment wires, broadcasting cables, high-frequency coaxial cables, and the KORIKI™ high-strength cable line); electronic materials (WILMINA™ EMI shielding films for FPC/FFC, functional pastes for via-filling, SMT and circuitry, and gold/silver/copper/palladium-copper bonding wires); and sensors and medical products (water leakage detection systems, OCT interferometer modules, PDT light diffusers, fiber Bragg gratings, and optical fiber couplers). The company also provides environmental analysis services (dioxins, soil, water, air, asbestos, industrial waste) through the Tatsuta Environmental Analysis Center.

The company's underlying technology stack rests on polymer compounding, fine particle dispersion, optical fiber processing, and functional paste formulation. Proprietary technology assets include KORIKI™ high-strength cables based on special alloy technology with dramatically improved bending resistance; metalizing-type via-filling pastes (MP series) that form intermetallic layers with PCB electrodes for high-speed data transmission; OCT interferometer modules with stable state-of-polarization characteristics against temperature changes and wideband optical fiber couplers with high wavelength flatness from 840nm to 1700nm; FBG manufacturing capability across an unusually wide 530nm–2100nm wavelength range with proprietary orthogonal fusion for polarization-maintaining fiber lasers; water leakage sensors with 3ml or less detection sensitivity, weak-energy circuit design (12.5VAC or lower), wire-break detection, and NFPA262 compliance; and nano-copper ink technology licensed from Copprint for PCB metallization. The functional films business achieved Scope 1 and 2 carbon neutrality in April 2022, with CO2 emissions reduced 68% by FY2022 (to 6,365 tons from 21,829 tons in FY2019) and a 90% reduction target by FY2025. The company holds ISO 22301 BCMS (since July 2016), ISO 27001 ISMS (since January 2023), RoHS compliance, UL94 VTM-0, NFPA262, and a 98.3% recycling rate across Japanese operations.

TATSUTA runs a B2B enterprise field-sales model, going to market via direct inquiry forms, the affiliate company Tatsuta Tachii Electric Cable Co., Ltd., overseas manufacturing in Malaysia for silver wire, and active participation in industry trade shows (MD&M West, CAR-ELE JAPAN, MEDICA, TATSUTA EXPO online). Pricing is quote-based and not publicly disclosed. Revenue is generated predominantly through hardware sales across the three product pillars and through environmental analysis services, with end customers being major manufacturers in semiconductors (LEDs, memory, NAND), automotive (heat-resistant sensors, water-cooling battery sensors, EV wiring), industrial FA/robotics (KORIKI cables), communication equipment (PWB pastes, FPC/FFC shielding), medical devices (OCT, PDT), data centers and critical infrastructure (water leakage detection), and broadcasting/media (high-frequency coaxial cable). The company employs a horizontal segmentation approach across seven end markets. In April 2023 TATSUTA established a dedicated New Business Development Department focused on global open innovation with startups and M&A; this unit has executed the UTM Corporation share acquisition (announced August 2025), a strategic license and equity investment in Copprint Technologies (January 2023), and is engaged with six startups in total.
