Koga ALL

What Koga ALL does

Koga All Co., Ltd. (古賀オール株式会社) is a Tokyo-headquartered Japanese steel processing and distribution company founded in 1947 and operating as a primary designated trading company for Nippon Steel, a status originally granted by Sumitomo Metal Industries in 1982. The company runs four integrated coil centers across Tokyo, Gunma, Miyagi, and Nagano, equipped with leveler shear, slitter, shearing, and mini leveler shear lines that process hot-rolled, cold-rolled, pickled, and surface-treated steel sheets to customer specifications. Through its wholly-owned logistics subsidiary Koga Logistics Co., Ltd. and a group fleet of approximately 50 trucks, Koga All delivers processed steel nationwide to over 500 manufacturing customers spanning automotive parts, construction materials, home appliances, industrial machinery, and metal processing. The company also operates related businesses including used truck sales through Asian Way Co., Ltd., and pursues sustainability initiatives such as heat-reflective coatings (awarded the FY2025 METI Minister Award), 100% non-fossil-electricity operations, and the Replaboard recycled construction material. In April 2026 Koga All completed a full corporate rebranding under the 'Koga for All' concept and a new leadership team led by President & CEO Teruhide Furuhata, positioning itself as a broader manufacturing-infrastructure partner rather than a pure steel intermediary.
