The Japan international has been a key member of Walter Mazzarri's team this season.
"Tottenham have been following him for a while but there is nothing more than that," Roberto Tukada told Calciomercato.
"He still has more than two years left on his contract with Inter and we want to renew.
"I think we will talk during the summer. The player is happy at Inter and there is no reason to think he will change teams."
