Officer
I am scheduled to assume the role of Group President and Chief Executive Officer of the Septeni

The Digital Marketing Business, our core business, has experienced various changes in the businessenvironment.

The rapid progress of digitalization in lifestyles, consumer behavior, working styles, and otherareas has led to the demand for digitalization at every starting point in society, and the demand for digitalmarketing is growing ever more.
I am very honored to receive a baton from Sato in such an era and be able to contribute to the growthof the Group with a new management team. With the Group’s mission and vision as a guide, we will work
