Announcement Of Change Of Titles

We wish to announce that there has been a title change for Takashi Someda, previous title “CTO (Chief Technical Officer)” to  “CBO (Chief Business Officer)” and Naoki Kitora, previous title “CDO (Chief Data Officer)” to “CTO (Chief Technical Officer)”, effective January 1, 2021.
