Free from radioactive contamination 

After the terrible reactor accident in Fukushima in March 2011, we are understandably often asked about the contamination of our teas. For this reason, we regularly have samples analysed in an independent German laboratory. 

Thanks to the great distance between the KEIKO organic tea gardens in southern Kagoshima and the Fukushima region to the north, all analyses since 2011 have confirmed the safety of all KEIKO teas.
