Discontinuation of Social Courtesies and Gifts to Medical Institutions and Healthcare Professionals

In line with recent global ethical initiatives, the Asia-Pacific Economic Cooperation (APEC) has established the Kuala Lumpur Principles̶voluntary guidelines that define ethical standards for interactions between the medical device industry, healthcare professionals, and patients.

The Kuala Lumpur Principles aim to promote greater transparency and integrity in relationships within the healthcare sector. These principles call for the avoidance of providing gifts, including items of nominal value, cultural courtesies, entertainment, or recreational benefits, in order to maintain a trustworthy and sound medical environment.

In response, the Japan Federation of Medical Devices Associations (JFMDA), the principal industry organization in Japan, has revised its Medical Device Industry Promotion Code to incorporate these principles.

As a member company of the JFMDA, our organization will comply with the revised code and will begin phasing out the provision of social courtesies, gifts, and similar offerings to healthcare professionals starting January 2026. Details regarding the implementation of this policy will be provided as they become available.

We appreciate your understanding and cooperation as we work to uphold the highest ethical standards in our industry.
