Message from the President

Our Company, which grew out of Isuzu Marine Engine Inc. founded in 1947, made a new start in 2013 as Isuzu Motors Engine Sales when we incorporated the industrial engine business of the Isuzu Group.
All of our products leverage Isuzu’s experience with building light weight truck engines with low fuel consumption and outstanding environmental performance.
Our goal is to contribute to society by supporting affluent living as a trusted partner while responding flexibly to changes in this era of uncertainty about the future, strengthening our ability to meet diversifying customer requirements regarding quality, cost, and deadlines, and enhancing customer satisfaction.

Management Policy

Ensuring Compliance

Isuzu Motors Engine Sales aims to be a sound company which contributes to society and is worthy of 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 fulfil 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 judgement. Our culture supports interactive communication and active reporting, liaison, and consultation for a speedy resolution when there are any doubts.

Basic Compliance Policy

1.Gaining Customers' Trust
We will gain our customers' trust by providing socially valuable products and services that enrich their lives.
2.Fair and Sound Activities
We will conduct business in the spirit of free and fair competition. Further, as a good corporate citizen committed to a healthy and fair relationship with host governments, we resolve to avoid contact with any anti-social groups or organizations.
3.Disclosure of Corporate Information
We will disclose corporate information to both shareholders and the public in a timely, appropriate and fair manner.
4.Respecting Employees
We will provide a safe, comfortable working environment, with respect for employees' individuality, so that they can make the most of their abilities.
5.Protecting the Environment
As a good global citizen, we will work to protect the environment through our business activities, and continually strive to take the initiative with environment preservation activities locally and worldwide.
6.Contributing to Society
As a good corporate citizen, we will make a positive contribution to society.
