Kosogui is a former Japan U17 captain who has accrued some Conference League experience with his Swedish side. 

Eintracht feel Kosugi is ready to contribute

“In Keita Kosugi, we have signed a young left-back who, in addition to his technical skills on the ball, also brings a high level of pace and work ethic to the table,” SGE sporting director Timmo Hardung noted in a club statement. “He has already proven his qualities as a regular player in the Swedish league and in the European Cup and has great potential for improvement.”
