President’s Message

Ever since Koatsu Gas Kogyo Co., Ltd. was founded in 1958, our corporate activities have been inspired by our basic philosophies of “Harmony among People, Technology and the Environment” and “Safety and security” and we have been on a constant quest to contribute to social development and to help enrich people’s everyday lives through our gas business, chemical products business and IT solution business.

We have remained steadfast in this commitment over the years and as society has developed in different ways. Today, the severity of various social issues is intensifying and the international community is striving to create a sustainable society by achieving the SDGs and other goals. In such a situation, I believe it is vital for us as managers to always refer back to our company’s original driving commitment and fundamental starting point.

Our business environment may be changing on a near daily basis. We believe that being more responsive to change and how to stay ahead of the curve will be the lifeblood of companies in the future.

We are determined to continue steadily implementing measures that will enable us to evolve into an even stronger company that enjoys sustainable growth fueled by stepping up to the next challenge of change for progress, and with a future-oriented perspective that looks one step ahead, keen sense of speed, flexible judgement and unswerving corporate philosophy.

In these uncertain and unclear times, we will reassess the “character of Koatsu Gas Kogyo Group” and, whatever the situation, the Group as a whole will respond flexibly and flexibly, building long-term relationships of trust with our customers and becoming a company that is needed by society.

We look forward to your continued understanding and support.
