Okocha will once again team up with former Bolton number two Phil Brown, who is now in charge at the KC Stadium.
"Phil influenced me to come here and I hope I will repay him for that," revealed the 34-year-old playmaker.
"He has given me another opportunity to come and enjoy life in England.
"Hull made it clear how ambitious they are. They have a new chairman at the club and they want to take Hull to a new level.
"I've got those ambitions and I'm glad to be back on the scene.
"The KC Stadium reminds me of the Reebok and hopefully I can achieve at Hull what I achieved at Bolton.
"It is a very physical league, but if I can play in the Premiership, then I won't have any problems playing in the Championship."
