Social Activities

Working in Harmony with Local Communities

At each of its business sites, the Mitsui Chemicals Group believes that relationships of trust, based on close-knit relations with everyone in the local area, are crucial to the normal and stable operation of its businesses. The Group thus provides opportunities for communication with everyone in the vicinity of its facilities.

Local Communication at Each Business Site

At each of our business sites, we engage in communication with the neighborhood communities, and the comments and opinions we receive are reflected in the management of our business sites as appropriate.

For example, we invite local residents living in the vicinity to opinion exchange meetings and tours of our facilities. At the opinion exchange meetings, we provide an overview of the Works and showcase our efforts to protect the environment, safety initiatives and activities designed to contribute to society. Lively discussions have ensued from residents living in the vicinity of our facilities speaking about their day-to-day feelings and any requests they have. Additionally, we receive complaints/grievances on plant operations through various channels, including by direct contact or through local government, and each plant has a tracking mechanism in place to consider and implement appropriate responses.
