REPROCELL Japan GMP Facility
Cell-based Product Manufacturing for Clinical Research

The Tonomachi REPROCELL Regenerative Medicine Center is located in the King Skyfront area of Tonomachi, Kawasaki City, Japan. The King Skyfront is a global strategic hub concentrating Japan's most advanced life science industries and research institutions. Positioned directly across from Haneda Airport, the site provides an ideal environment for collaboration with domestic and international research and medical institutions.
GMP Facility for Manufacturing Cell-based Products
Our manufacturing center holds an MHLW license for the production of specified processed cell products (Facility No. FA3200006) under Japan’s Act on the Safety of Regenerative Medicine. This license requires compliance with strict quality, safety, and operational standards. Under this license, we are authorized to perform contract manufacturing of cells for clinical research, all within a fully audited and controlled quality management system
Facility Environment & Rigorous Quality Control
The facility includes multiple cleanrooms with graded air‐cleanliness levels, pressure-controlled zoning, and unidirectional personnel and materials flow to minimize contamination risk. All cell processing is performed in aseptic biological safety cabinets. Environmental controls are continuously monitored (temperature, pressure, and airborne particulates) with real-time deviation alerts. In addition, routine environmental monitoring of airborne, settling, and surface microbial loads is conducted across all classified areas.
Key Manufacturing Experience
Our center has a proven track record in the manufacturing of:
