What Nemoto Kyorindo Co. does

Nemoto Kyorindo Co., Ltd. (株式会社根本杏林堂) is a privately-held Japanese medical device manufacturer founded in 1939 and headquartered in Bunkyo-ku, Tokyo, with manufacturing and R&D operations in Kawaguchi, Saitama. The company specializes exclusively in contrast media injectors used in CT, MRI, angiography, and intravenous pyelogram (IVP) imaging, and operates across three primary device categories—CT injectors (Dual Shot GX 7, Smart Shot, Auto Enhance A-800), MR injectors (Sonic Shot 7, acot S), and angiography injectors (PRESS DUO elite, PRESSPRO GEO-150)—supported by an IVP pump, a network-based information management system (CE Evidence), and proprietary disposable consumables. Underlying technology centers on proprietary electromechanical engineering, including non-magnetic ultrasonic motors for MR-suite use, dual-cylinder/dual-head configurations for simultaneous contrast-and-saline injection, real-time pressure monitoring, body-weight-based protocol delivery, and the CUG (Contrast Agent Use Guidance) safety system integrated into angiographic injectors.

The company operates a direct enterprise field-sales model in Japan through six regional offices (Tokyo, Osaka, Nagoya, Sapporo, Fukuoka, Sendai) that engage hospital radiology and imaging departments, supplemented by a customer service hotline and after-sale maintenance operations. Revenue is generated through hardware sales of injector systems, recurring revenue from proprietary disposable syringes and extension tubes, and after-sale installation, inspection, and maintenance services; pricing is not publicly disclosed and is contact-based via regional offices. International sales are managed through a dedicated International Division at the Tokyo headquarters. Certifications include ISO 9001 (2001) and ISO 13485 (2003). The company is led by President and Representative Director Shigeru Nemoto (根本 茂), consistent with founder-family governance, and has no identified institutional, private equity, or venture capital ownership.

Core offering

Nemoto Kyorindo Co., Ltd. designs, develops, manufactures, and sells contrast media injection systems and related consumables for diagnostic imaging. Its product portfolio spans CT injectors, MR-compatible injectors, angiography injectors, and IVP pumps, supplemented by the CE Evidence network-based data management platform and disposable syringes/tubes. The company also provides after-sale installation, inspection, and maintenance services for its medical devices across Japan and select international markets.

Product overview

Nemoto Kyorindo Co. is a Japanese medical device manufacturer specializing in contrast media injectors for diagnostic imaging. The product portfolio is organized into three core device categories—CT injectors (Dual Shot GX 7, Smart Shot, Auto Enhance A-800), MR injectors (Sonic Shot 7, acot S), and angiography injectors (PRESS DUO elite, PRESSPRO GEO-150)—supplemented by a urological IVP pump. The company also offers CE Evidence, a network-based information management system that centralizes contrast examination data across injector devices. Disposable syringes, extension tubes, and service/maintenance programs round out the ecosystem. The injectors share common design principles: body weight-based dosing protocols, pressure monitoring, and dual-barrel/saline flush configurations for multi-phase injection scenarios.

Direct peers

• Bayer (Medrad): Bayer's Radiology division (formerly Medrad) is the global market leader in contrast media injectors across CT, MR and angiography, with deep OEM relationships to imaging equipment vendors — the most direct overlap with Nemoto's product portfolio.
• Bracco Imaging: Italian-based Bracco is a leading contrast media supplier that also develops and sells contrast injectors (e.g., Empower line) across CT, MR and angiography — directly competing with Nemoto in both injector hardware and imaging consumables.
• Guerbet: French-based Guerbet is a global contrast media and imaging solutions company (OptiStar, Illumena injectors) that competes with Nemoto across CT/MR contrast injection, particularly outside Japan.
• ulrich medical: Germany-based ulrich medical develops and manufactures contrast media injectors (CT motion, max 3D) and spine products, making it a close mid-sized direct peer comparable in scale and product focus to Nemoto.
• Medtron AG: Germany-based Medtron AG is a specialized contrast media injector manufacturer (Accutron HP, MR injection systems) targeting CT and MR injectors — directly comparable to Nemoto in scope and product specialization.

Broad incumbents

• GE Healthcare: GE Healthcare manufactures CT and MR scanners and also produces contrast injectors (e.g., OptiVantage) alongside its own contrast media. Its OEM bundling with imaging systems makes it a broad incumbent overlapping Nemoto's CT injector offering.

Emerging players

• AngioDynamics: AngioDynamics markets angiographic contrast injection systems and disposable accessories, overlapping Nemoto's PRESS DUO / PRESSPRO angiography injector portfolio in the cardiovascular imaging segment.

Regional players

• Shenzhen Anges Medtech: China-based medical device manufacturer offering CT/MR contrast injectors and consumables across Asia-Pacific, providing regional competition in markets neighboring Nemoto's Japanese stronghold.
