EMI Factory

What EMI Factory does

EMI Factory Co., Ltd. is a privately held Japanese medical device development company founded in October 2006 in Nagano by representative director Noriaki Emi. The company operates as a developer-manufacturer of specialized surgical instruments and supporting systems, organized into three product divisions: Surgical Device Products (minimally invasive surgery instruments for MICS/VATS/TAPP/LAP-C, super microsurgery instruments capable of handling 0.5mm vessels, perforator flap surgery instruments, and dental microsurgery instruments), Surgical Training Systems (the Go Surgeons web application and physical training simulators for rigid endoscopy across cardiovascular, thoracic, gastrointestinal, and super-microsurgery specialties), and Medical Automation Systems (proprietary motor control technology for medical robotics and a cancer cell examination module with web-based AI tissue assessment).

The company's underlying technology rests on proprietary motor control systems and ultra-precision instrument engineering developed in collaboration with practicing surgeons, including what it describes as the world's smallest needle thread for 0.5mm microvascular anastomosis. Manufacturing is conducted at the Okayama factory office, with product development and administrative functions at the Nagano headquarters and dedicated sales operations at the Tokyo office. The company holds Japanese Ministry of Health, Labour and Welfare authorizations for manufacturing and selling medical instruments and has obtained medical device sales approvals in various international markets.

EMI Factory monetizes through multiple channels: one-time sales of surgical instruments to hospitals and through overseas distributors; flexible contract structures for training simulators including outright purchase, rental, lease, and subscription; Amazon marketplace distribution of training products; and joint R&D / made-to-order development services for medical device manufacturers. Customer segments include surgeons and surgical teams across cardiovascular, thoracic, abdominal, reconstructive, and dental specialties; medical device manufacturers requiring motor control modules and automation solutions; and medical institutions and training centers. The company has cumulatively completed 255+ product development cases and shipped 26,000+ units, with products deployed in over 40 countries and regions worldwide (the company website cites 45 countries). The business is entirely self-funded with ¥20 million in registered capital, no disclosed institutional investment, and no acquisitions or partnerships in the public record.
