The Scot will face either Jarkko Nieminen or Igor Andreev in the second round should he beat Ito, whom he has never played.
Should Murray then come through potential match-ups against Bernard Tomic and Alexandr Dolgopolov, he would likely face David Ferrer in a tricky quarter-final before meeting the king of Roland Garros in the semi-finals Rafael Nadal.
Nadal faces Simone Bolelli in the first round, while world number one Novak Djokovic plays Potito Starace and Roger Federer goes up against Tobias Kamke.
Djokovic and Federer could be set for a repeat of their epic last-four clash in 2011, which the Swiss won in four sets to end the Serb's 43-match winning streak.
Djokovic has won the three Grand Slams since then at Wimbledon, the US Open and in Australia. Should he claim a fourth in a row, he would be the first man to do so since Rod Laver in 1969.
Ito reached the second round of this season's Australian Open - his best showing in a Grand Slam - before going down to Tomic.
World number four Murray lost in straight sets to eventual champion Rafael Nadal at the semi-final stage last year.
