Honda has been linked with a move to AC Milan and the player said that he would seriously consider a summer transfer should the Italian side make a bid.
"I don't know where I'll be taking the next step yet, but I know I've got a chance to play for a big club," Honda told the Japan Times. "I have until August so I'll wait and see.
"If I go to a big club, I'll become an infinitely better player. The improvement I'll make then will be anything but minor.
"I'm the type to soak up everything and anything in my surroundings, and if I play with better players, I'll get better. It's how I've been able to get this far in my career."
Honda's current deal at CSKA expires in December.
