Narita

What Narita does

Narita Mfg., Ltd. (株式会社成田製作所) is a Japanese precision metal fabrication company founded in 1938 and headquartered in Nagoya, Aichi Prefecture. The company specializes in rail vehicle components—most notably gangways (horo/幌), the flexible connectors between train cars—where it holds 100% market share for Shinkansen applications and over 90% overall market share for Japanese rail vehicle connectors. Its rail product portfolio extends to doors, water and fuel tanks, ducts, structural components, and interior parts for Shinkansen, commuter, rapid transit, monorail, and LRV vehicles.

The company's second core business is aluminum welding and fabrication for motorcycle OEMs, producing body frames, swing arms, seat rails, fuel tanks, tank rails, and muffler heat guards for global manufacturers including Suzuki and Kawasaki Heavy Industries. Underlying capabilities include TIG, MIG, and CO2 welding of aluminum; sheet metal processing; precision machining; and anodizing (alumite surface treatment) at its dedicated Mito Alumite Plant (operational since 1997). The company holds 41 patents including 32 overseas patents, and maintains ISO9001 and ISO14001 certifications.

Narita operates a B2B custom manufacturing model with direct sales to rail vehicle OEMs (Nippon Sharyo, Hitachi, JR Group) and motorcycle manufacturers, supported by sales divisions at headquarters, manufacturing plants, and the Tokyo Sales Office. Revenue is generated through quote-based, multi-year contracts for bespoke components manufactured to customer specifications. The company has expanded internationally through a Chinese joint venture (Tangshan Narita Railway Products, 2000), a technical partnership with South Korea's Woojin OHM (1992), and a wholly-owned US subsidiary NARITA MFG., INC. in Illinois (2012). It diversified into the aircraft industry in 2013 and operates an adjacent graphic printing subsidiary called NAVICOM. The company is privately held, family-controlled (Narita family), with paid-in capital of ¥54 million and approximately 234-249 domestic employees plus 16 US employees.

Direct peers

• Nabtesco Corporation: Japanese manufacturer of precision components for rail vehicles (brake systems, door systems, gangways) and aircraft equipment; directly comparable to Narita as a tier-1 supplier of rail vehicle subsystems to Japanese and global rail OEMs.
• Yorozu Corporation: Japanese supplier of automotive and motorcycle suspension components (including aluminum-intensive parts); directly comparable manufacturing scope for motorcycle OEM aluminum components.
• Nippon Sharyo, Ltd. Japanese passenger rail vehicle manufacturer and Narita's largest customer; comparable as a Japan-based rail industry specialist, though upstream (vehicle assembly) versus Narita's downstream (component) position.

Broad incumbents

• Kawasaki Heavy Industries, Ltd. Diversified Japanese manufacturer of railway vehicles, motorcycles, and aerospace — both a Narita customer (motorcycle aluminum components) and an indirect peer in rail vehicle system integration.
• Knorr-Bremse AG: Global market leader in rail braking and on-board systems including door and gangway systems; serves the same global rail OEMs as Narita but at much larger scale and broader product scope.
• Wabtec Corporation (formerly Faiveley Transport): Global rail equipment supplier including gangway, door, and interior systems for passenger rail; Faiveley Transport historically competed directly with Narita in gangway technology before Wabtec acquisition.
• Hitachi Rail (Hitachi, Ltd.): Global rail systems integrator and Narita customer; operates across rolling stock, signaling, and services — a broader incumbent competing for integrated scope versus Narita's specialized component focus.
• Sumitomo Heavy Industries, Ltd. Diversified Japanese industrial manufacturer with transportation equipment and precision components divisions; comparable as a multi-plant Japanese metal-fabrication and OEM supplier with overlapping rail/motorcycle exposure.
• Aisin Corporation: Major Japanese automotive parts manufacturer with aluminum chassis and body components; relevant peer for Narita's aluminum motorcycle frame/swing arm business and precision metal fabrication competency.
• Westinghouse Air Brake Technologies (Wabtec) — Door & Gangway Division: Through the legacy Faiveley platform, this division directly competes in gangway and door systems for high-speed and commuter rail globally — the closest international comparable to Narita's gangway franchise.
