Kennedy, who joined the J-League club in June, has netted three times in his first three appearances prompting plaudits from his Japan international strike partner.
"He just plays a nice, simple game," Tamada told the Daily Yomiuri.
"If you're free, he has the vision to pick you out and he's so tall that he can win everything in the air.
"He's your classic target man.
"He's pretty good technically, and he can hold up the ball if we need him to. We didn't have a player quite like him before, and I personally wanted someone like him."
"The guys on the team, the whole club has made it quite easy for me to settle in," Kennedy said.
"From day one, they've helped with everything, and it's important."
