Hiruta Kogyo

What Hiruta Kogyo does

Hiruta Kogyo Co., Ltd. (ヒルタ工業株式会社) is a privately held Japanese automotive parts manufacturer founded in 1928 in Fukuyama, Hiroshima Prefecture, and now headquartered in Kasaoka, Okayama Prefecture. The company operates an integrated one-stop production process spanning advance development, 3D CAD/CAE design, in-house die and tooling fabrication, sheet-metal press forming, welding (spot, arc, TIG), painting, machining, assembly, and quality assurance. Its core product portfolio covers automotive safety-critical and structural components including suspension parts (cross members, arms, axle housings, torsion beams), pedal systems (brake and parking brake pedals), powertrain parts (differential cases, carriers), body/chassis, steering components, air-conditioning parts, and a growing EV components line (motor mounts, battery brackets, unit members). Adjacent revenue streams include industrial equipment and agricultural machinery parts (Caterpillar Japan, forklifts) and medical-device components such as stainless-steel manifold assemblies for medical gas regulators.

The company is a tier-1/tier-2 direct supplier to major Japanese and international automotive OEMs, including Mitsubishi Motors (a customer since 1946), Suzuki, Isuzu, Beijing Motors, and air-conditioning parts to Daikin Industries. Pricing is negotiated contract-by-contract with automotive customers under annual negotiation cycles; revenue is generated through hardware sales under long-term supply agreements. Its distribution model is a direct OEM supply arrangement with just-in-time delivery from local manufacturing bases. To serve global customers, Hiruta Kogyo operates 11 factories across 6 countries — Japan (Kasaoka HQ, Soja, Kibi, Toyohashi, Hiratsuka, Ota), USA (Crawfordsville, Indiana), Mexico (Silao, Guanajuato), Thailand (Bangkok, Chonburi via JV), China (Foshan, with Changsha branch), and Indonesia (Karawang) — supplemented by international partners including a 51% interest in Bangkok Eagle Wings, a JV with Summit Laemchabang, and a technical partnership with India's Madhusudan Auto. With roughly 1,020 employees as of April 2025 and successive domestic acquisitions (Kurefactory in 2023, Heian Seisakusho in May 2026), the company continues to consolidate capacity and capability while preserving a decentralized group structure led by founder-family Chairman Hiruta Shinzō and President/COO Oda Takayuki.

Revenue model

1. Automotive Parts Manufacturing and Sales: Design, development, and manufacturing of automotive components (suspension parts, pedal systems, powertrain parts, body/chassis parts, steering parts, air conditioning parts, EV components) sold directly to automotive OEMs and tier-1 suppliers. Revenue is generated through the sale of manufactured parts under long-term supply agreements with automotive manufacturers.
2. Industrial Equipment and Agricultural Machinery Parts: Manufacturing and sale of industrial machinery components and agricultural machinery parts, including parts for forklifts and other industrial vehicles. These non-automotive segments diversify the customer base and revenue streams.
3. Medical Device Parts: Manufacturing of precision medical device components such as manifold assembly cases for medical gas (oxygen, anesthesia) regulators, sold to medical equipment manufacturers.
