The Japan international is set to sign permanently with Inter in the coming days.
"I think his transfer is just a formality," Cesena sporting director Lorenzo Minotti told Radio Sportiva on Saturday.
"A deal was pretty much already agreed in January, but then there were a few bureaucratic problems. The signatures are just missing now."
The Japanese international, an attacking left-back, joined Inter on loan in January just six months after moving to Serie A.
"The deal will certainly be concluded next week, where we will also talk about a few interesting young Inter players who could come to us," Minotti added.
