Marketing Communications

Our group aims to create a society where people can live long, safe, comfortable, and healthy lives even in the era of 100-year lifespans, through a variety of housing-related products and services, including detached houses for sale.
When purchasing real estate, due to the highly specialized nature of the product or service, it is necessary to provide easy-to-understand explanations that Customer can understand accurately. Iida Group Holdings carefully and accurately represents the quality and value of our group's products and services, and conducts responsible marketing activities. We conduct marketing communications based on the following concepts with the aim of gaining and expanding brand recognition and improving brand value.

Conduct public relations activities that place the highest priority on transparency and fairness.

We will respond with the highest priority on transparency and fairness to the various press and ultimately to society.

Appropriate information disclosure

We strive to provide the latest information regarding products, services, businesses, etc. in an appropriate, easy-to-understand, fact-based, and non-misleading manner.
In addition, we will always be considerate to all Customer and will not use discriminatory or offensive expressions. In marketing communications aimed at children, special consideration should be given to the way they are expressed, and avoid depictions or depictions that encourage activities that are dangerous or inappropriate in light of their physical, mental, or social abilities. I don't express myself.

Aiming for overall optimization rather than individual optimization

In our public relations activities, we strive to not only achieve individual objectives, but also contribute to achieving the objectives of the group, the real estate industry, and society as a whole.
