Yasuhito Endo, Shinji Okazaki and Keisuke Honda scored in the first half to give Japan a big lead against the tournament debutants in wet and windy conditions at Hunter Stadium.
Maya Yoshida scored after the break from Shinji Kagawa's cross to complete the rout.
Ahmed Mahajna was sent off mid-way through the second half to make it a tough first tournament start for the Palestinians, who qualified by winning the 2014 AFC Challenge Cup in the Maldives.
Japan has won four Asian Cup titles in the past six editions and is seeking a record fifth continental crown in Australia.
