Tokyo Radiator Mfg. Co., Ltd. specializes in the manufacture and sale of heat exchangers and body components primarily for commercial vehicles, construction machinery, industrial machinery, and agricultural machinery. Its core product portfolio includes high-efficiency radiators, intercoolers, EGR coolers, oil coolers, cooling modules, fuel tanks, oil pans, SCR tanks, and sub tanks. The company caters mainly to markets in Japan, China, and Southeast Asia with a focus on lightweight, high-performance, and environmentally compatible cooling solutions tailored for diesel, petrol, and fuel cell electric vehicles.
Founded in 1938 and headquartered in Kawasaki City, Japan, Tokyo Radiator leverages advanced manufacturing technologies such as ultra-deep drawing for pressing and assembling components. The company actively develops products that support carbon neutrality, including radiators for fuel cell electric vehicles and modular cooling systems that balance thermal efficiency with emissions reduction. Tokyo Radiator operates subsidiaries like Chongqing Tokyo Radiator Co., Ltd. in China and PT. Tokyo Radiator Selemat Sempurna in Indonesia, facilitating its regional footprint.
In recent developments, Tokyo Radiator has undergone significant strategic shifts, including the buyback of its own shares, which resulted in former parent company Marelli Holdings reducing its stake substantially by February 2023. The company also transitioned to the Standard Market of the Tokyo Stock Exchange from the Second Section in April 2022. Financially, fiscal year 2024 showed notable growth in operating and ordinary income, despite a net loss attributable to shareholders. Tokyo Radiator maintains partnerships and licensing agreements for manufacturing technology with companies in Thailand and Indonesia, and pursues governance improvements amid shareholder activism. The company continues to innovate in thermal management products to meet evolving automotive emission regulations and energy transition goals.
