About Japan MDM

Japan Medical Dynamic Marketing, INC. was established in 1973 as Hospital Services Co., Ltd., and changed its current name in 1981 based on the following philosophy.


Faithful to our corporate policy of “contributing to medical care,” we will demonstrate the characteristics of a trading company and a manufacturer in a well-balanced manner for the health of people in the world.


While broadly and deeply engaged in the medical industry, we will pursue robust business development and invest a lot of passion in developing original products.


With a broad view of the rapidly evolving medical industry and the new era, we will accurately grasp needs and promote business worldwide.

To fulfill the needs of the expanding medical field with valuable medical equipment, particularly in the field of orthopedics, Japan MDM has been promoting unique business development by integrating “trading company functions” and “development-driven manufacturer functions.”
