Research Group on Metal Allergy and Product Safety

Purpose

A wide variety of metal accessories and everyday products are an essential part of our daily lives.

However, there have been numerous reports of skin irritation and allergic reactions caused by contact with metallic components in these products, sometimes leading to adverse health effects. It is estimated that a significant number of individuals in Japan, particularly women, are affected by metal allergies.

Metal allergy is a condition that can often be prevented through the appropriate use of products that do not release metal ions. In order to enable consumers to safely select and use metal products, it is necessary to establish appropriate regulations, including standards for metal release and labeling requirements.

In collaboration with industry and governmental organizations, we aim to create an environment in which consumers can confidently choose and use metal products.
