CEO Messege



Kazuhiro Morita

We are celebrating a quarter of a century since our founding, and we would like to thank all of our business partners for their kindness.

The expansion of the network has brought the world closer to us.

In a global society without managers, there is no easy promise of success for a winner, and curiosity for diversity, respect for harmony, and continued sturdiness are essential.


Taking the opportunity of the opening of our website, Sumiko Air Co., Ltd. will continue to disclose information more than ever, ensure thorough compliance, and strengthen our efforts in environmental activities.

We also hope that we will be able to work together with our business partners for a new quarter of a century, with careful steering, by always remembering the starting point of the establishment of Sumiko Air, which is “we want this kind of function”.
