The experienced former Stuttgart striker is eager to begin his career in the J-League as the club look for the goals to help fend off relegation
The 11-year Stuttgart veteran will wear the No. 33 shirt alongside new team-mate Diego Forlan and Japan international Hotaru Yamaguchi.
In explaining his reasons to come to Japan, Cacau cited the high level of play in the country's J-League as well as the recommendation of former Kashima Antlers player and manager Jorginho.
"I'm honoured to have signed a contract with Cerezo and want to experience joy with everyone," Cacau said in Japanese at the start of the question and answer session.
"I want to use what I've experienced in my career to support Cerezo not just as a player, but as a person.
"I feel that I'm most comfortable as a second striker. I'm confident in my ability to control the ball and distribute passes to my team-mates."
Cacau, who played alongside Samurai Blue members Shinji Okazaki and Gotoku Sakai at Stuttgart, is expected to make his bench debut as early as August 23 when Cerezo face defending champions Sanfrecce Hiroshima.
"We made the offer [to Cacau] because of our trouble scoring this season," club president Masao Okano commented.
Cerezo are currently in 15th place after 19 rounds.
