The 21-year-old Nigeria international underwent his medical on Tuesday before signing a deal, which includes an option for the Turkish club to buy him permanently at the end of the loan.
"The target is to get a lot of playing time and help Kasimpasa achieve their objectives," he told BBC Sport.
"I've come to Turkey to reciprocate the club's determination to bring me here. I want to show the manager and the fans that they have made a good choice and I am completely focused on breaking into the squad and prove myself here.
"They have strong faith in my ability and I need to prove it. Last season was difficult because of injuries which affected me both at club and international level but I have put all that behind me.
