Honda is moving to Milan from CSKA Moscow.
"I am certain Honda has the quality to play in Serie A," said Zaccheroni.
"He has the right characteristics to shine at a world class side like Milan, whether they are physical, technical or moral characteristics.
"Keisuke is a player of great personality and on top of technique I consider that to be fundamental in a player. This aspect will really help him.
"He will find a lot of competition, as Milan in their history have had some extraordinary players wear the Number 10.
"Honda must not consider signing for Milan as the pinnacle of his career, though. The important thing is not to arrive at Milan, but to arrive at Milan and be able to play consistently."
