The Japan international is out of contract at current club CSKA Moscow in December, meaning he can join a club for free in January.
AC Milan held talks over the summer, and appeared firm favourites to seal the 27-year-old's signature come 2014 - but Honda admits that they are not his only option.
"Milan? They are an option, but not the only option. When the time comes, I will make a decision," Honda was quoted as saying on Football Italia when quizzed about his future destination.
"I have now decided I will leave my club at the expiry of the contract."
A host of Premier League clubs are reportedly keeping tabs on the 27 year-old, who scored in Japan's 3-1 friendly win over Ghana on Tuesday night.
