The various safety studies necessary for developing food and other products are required to not only have accurate data, but need to adhere to standards and specifications established by the government and other organizations. In regard to safety studies that are conducted in compliance with these standards and specifications, the Quality Assurance Unit strives to ensure the credibility of the entire study by inspecting the data objectively and rigorously. In addition, it also ensures the reliability of seed cultures for production sent by the Yakult Central Institute to overseas plants on a regular basis.

　Furthermore, since it is important for each individual researcher to have greater awareness and self-management in order to properly carry out their daily research work, it conducts research ethics training in collaboration with each department at the institute.
