Taiyo Shoji

What Taiyo Shoji does

Taiyo Shoji (大洋商事株式会社) is a privately held Japanese specialty steel trading company founded in October 1947 by former employees of Mitsubishi Corporation's metals and machinery departments. Headquartered in Tokyo (Chuo-ku), the company trades and distributes special steel materials (carbon steel, alloy steel, stainless steel, high-tensile steel, and super corrosion/heat-resistant steels such as titanium and Inconel), non-ferrous metals, metal powders produced via atomization, industrial machinery, plant-related equipment, IT/optical thin-film products, and finished cast and forged components. Its service portfolio extends beyond pure trading to include in-house processing: precision lost wax casting with tolerances as tight as ±0.13mm, cold/warm/hot precision forging (200g–4,000g weight range), and fiber laser cutting (May 2023 installation of a Tanaka FMR II 45X-TI12000 machine at the Urayasu Warehouse).

The company operates an integrated supply chain combining materials trading, custom parts manufacturing, and logistics services. Revenue is generated primarily through transaction-fee-based trading of specialty steel and processed parts to enterprise customers, supplemented by warehouse storage, cutting, and laser processing services delivered through wholly-owned subsidiary Taiyo Unso Co., Ltd. Customer segments include automotive (turbochargers, transmission components), construction machinery (cranes, excavators, hydraulic systems), steel mills (electric furnace parts, rolling mills), and IT/optics manufacturers (thin-film coatings, laser components, medical imaging). Distribution is executed through a direct enterprise field-sales model across six domestic Japanese branches and overseas group companies in China (Taiyo Special Metals Zhejiang, Taiyo Shoumao Pinghu, Shanghai office), South Korea (Taiyo Korea, Busan), Thailand (Siam Taiyo Shoji JV; TIDY METAL JV with Dainics Kogyo), and the Philippines (TAIYO SUBIC PHILIPPINES). A US subsidiary (TAIYO AMERICAS INC.) established in 2017 was closed in December 2022.

Taiyo Shoji's most recently disclosed annual revenue (FY2026, January period) was 441 billion JPY, down from 455B JPY in FY2025 and 513B JPY in FY2024. Headcount as of April 2026 stands at 132 standalone employees and 318 including affiliates. The company has maintained debt-free operations for decades, holds ISO 14001 certification (since January 2006), and is led by President and CEO Kitadai Hiroaki (北代 広明), who assumed the role on April 27, 2022, succeeding Kita Shinichi.
