What JMR does

JMR Co., Ltd. (JMR株式会社) is a privately held Japanese medical device manufacturer founded in 2011 and headquartered in Niigata Prefecture, in the Tsubame-Sanjo region historically known for precision metalworking. The company designs, develops, manufactures, and markets specialized surgical instruments and medical devices — primarily Class I devices — across multiple surgical disciplines including ophthalmology (cataract surgery aspiration tips), ear/nasal surgery (K-Cutter, Rhinomeasure V2, Tongue Lift), vascular surgery (Vein Stripper), orthopedics (Pelvicky pelvic splint, Wire Ring Roman Hook, Scaloon micro-instruments series with PVD coating), endoscopy (Endo Flower foreign body removal attachment), dentistry (PRF Stamper developed with Niigata University), and IV/catheter care (Namaran silicone fixation patches). Several products incorporate proprietary design elements such as spiral-step internal processing on the Solution Tip for cataract aspiration, and many are co-developed with named clinicians and academic institutions, embedding clinical feedback into the product development process.

The company operates a hybrid go-to-market combining B2B quotation-based sales to hospitals and surgical centers with a direct-to-consumer e-commerce channel (JMR ONLINE SHOP, launched in 2021) for select products. Revenue is generated primarily through one-time hardware sales of proprietary instruments, supplemented by recurring device maintenance services (PVD recoating, laser marking, and repair) offered to healthcare facilities. Distribution is domestic-only in Japan, with all products manufactured at the Niigata headquarters facility.

JMR holds ISO 13485 certification (renewed November 2019) and a Class I Medical Device Manufacturing and Marketing License (obtained August 2018 via the related B-Studio entity). The company has steadily expanded its catalog — adding multiple new SKUs each year between 2016 and 2023 — and has secured media coverage and exhibition presence (Go-Tech exhibition at Tokyo Big Sight, December 2022; Leverwell Nursing feature, 2023). No external funding rounds, institutional investors, or international expansion have been disclosed in the available data.
