Introduction to EFA Laboratories

EFA Laboratories, Ltd. (EFA) specializes in Japanese asbestos analyses, survey and consulting services. The laboratory is centrally-located in Kanda-Jimbocho, Tokyo. It was established in April 2006 under a joint venture agreement with California-based Forensic Analytical Laboratories, Inc. and Tokyo-based environmental consulting company.
