Ippodo's teabags are made from materials compliant with Japan’s Food Sanitation Act. However, at this time, we have not conducted specific tests to measure microplastics in our products. Research on the impact of microplastics (0.001mm–5mm in size) and even smaller nanoplastics on the human body is still ongoing.
We will continue to monitor studies conducted by public and specialised institutions both in Japan and internationally.
