Sustainability Activities

To Be Trusted by All and Develop in Harmony with Society

We strive to engage in corporate activities that are trusted by our stakeholders,
while giving due consideration to global environmental conservation and safety in our everyday lives.
Here, we introduce our sustainability activities, including our social contribution activities,
through which we aim to support the development of a sustainable society.



The importance of measures in relation to sustainability, such as human rights, climate change, and biodiversity, is becoming ever more important. Meanwhile, due to the supply chain disruptions brought by the spread of COVID-19, as well as growing geopolitical risks, our business environment has been changing rapidly.

We have identified “Sustainable” as one of the key concepts under our Conduct Guidelines. Toward finding solutions to a wide range of social issues, we will engage in autonomous business activities, through which we strive to provide, to our stakeholders, new added value in line with increasingly complex environmental changes, while ensuring thorough communication and accountability. By doing so, we aim to realize sustainable growth.
