Ensuring Compliance

Isuzu Motors Engine Sales aims to be a sound company that contributes to society and is worthy of the trust-a company where all officers and employees are aware of and take responsibility for their own conduct.
One of the three principles of our Management Policy is “continuously maintaining internal control and thorough compliance.” In order for the company to fulfill its corporate responsibility to society, to contribute to society, and to be worthy of trust, we recognize that compliance activities are the most important management task, and it is no exaggeration to refer to these activities as “risk management” on which company survival depends.
For these compliance activities to be effective, it is fundamental that every single individual upholds a high level of ethical and moral values and behaves in accordance with internal and external rules. To achieve this, we work hard to build a corporate culture that facilitates an ongoing practice of self-examination, including questioning whether something in day-to-day work is against laws and regulations, internal rules, or general good judgment. Our culture supports interactive communication and active reporting, liaison, and consultation for a speedy resolution when there are any doubts.
