   We have appointed a person in charge of the handling of personal information. We have clearly defined the employees who handle personal information and the scope of personal information they handle, and have established a reporting and communication system to the person in charge in the event that any facts or signs of violations of laws or handling regulations are identified. We conduct regular self-inspections of the status of personal information handling, as well as internal audits and third-party reviews.
