President’s Message

President’s Message

Since the Company’s founding in 1958, we have pursued the basic philosophy of “Harmony among People, Technology, and the Environment” and “Safety and security.” Through our gas business, chemical products business and IT solution business, we have strived to carry out our corporate activities with the intention of contributing to the development of society and the prosperity of people’s lives.

This desire has remained unchanged as time has passed and society has developed. As various social issues become more serious and the international community strives to realize a sustainable society, including the achievement of the SDGs, we believe that management that returns to this starting point will become even more critical.

In recent years, the speed of change in the management environment has continued to accelerate, and it has become necessary for companies to have management systems that can flexibly respond to various changes without being bound by preexisting concepts.

Even in this rapidly changing business environment, based on our unchanging corporate philosophy and while continuously keeping the balance between opportunity and risk in mind, we will consolidate the thinking powers and technological strengths that we have cultivated since our foundation and unite as a Group to steadily implement new measures for future growth in order to develop our business and contribute to a sustainable society.

We continue to build long-term relationships of trust with all of our shareholders, sincerely address social demands, work to achieve sustainable growth and enhance our corporate value, and aim to be a group company that is needed and trusted by society.

We look forward to your continued understanding and support.
