Indian hockey men's team will take on Japan in the last pool stage match at the second leg of the Four Nations Invitational Tournament here at the Gallagher Hockey Stadium in Hamilton on Saturday. India had previously defeated Japan 6-0 in the first leg at Tauranga. While the team will look to clinch a third-straight win after beating hosts New Zealand 3-2 in the first match, followed by a stunning win against Belgium against whom India had lost twice (1-3 and 1-2) in the previous leg, Chief Coach Sjoerd Marijne wants his team to work on their shortcomings.
