After a comprehensive 7-0 win over the hosts Bangladesh in their opening fixture of the 10th Hockey Asia Cup, Pakistan next faces Japan on Friday at Dhaka's Maulana Bhashani Stadium.
Japan is yet to reach the podium at the Asia Cup though they have finished fourth no less than four times.
Japan's lone victory came at the 2007 Asia Cup in Chennai, India where they defeated the Green Shirts 3-1.
That defeat meant Pakistan failed to reach the semifinals of a continental event (Asia Cup/Asian Games) for the first time. They eventually ended at the 6th spot.
