The former AC Milan star, signed a one-year deal with Victory in August and despite a strong debut season, looks set to leave.
The 32 year-old has seven goals and laid on five assists in 18 appearances, although he missed a chunk of the season with a hamstring injury.
"I still don't decide where I will play next year," Honda said.
"But I knew that I would stay for just [one] year so I hope no one is surprised, no one is disappointed."
Victory still has at least three games and up to five remaining this season, including two AFC Champions League matches.
