Social Contribution

Hiyoshi aims to be “social- and technology-oriented” with its corporate motto, “No company exists without social contributions and competence.” In line with this motto, we have maintained a commitment to contributing to both domestic communities and international society since our early days. Through over 50 years of activities, we have received more than 50 certificates of appreciation and commendations from the Minister of the Environment, the Minister of Health, Labour and Welfare, governors and various associations. Based on these achievements, as well as our philosophy, we will continue expanding our cross-border activities to further address environmental problems.

International Society Contributions

As environmental problems have no national boundaries, environmental conservation activities are not effective unless they are approached on a global scale. Therefore, Hiyoshi is engaged in activities to transfer their half-century's worth of expertise over to developing countries.

Domestic Community Contributions

Adhering to the concept that “No company exists without social contributions and competence,” we have cooperated with domestic communities and endeavored to support them through various contributing activities for many years.
