Before the break, Japan opened the scoring with Doan's cross, nodded down into Maeda's path.
A Powerful Start
Perisic scored Croatia's first major tournament goal from 14 yards in the 55th minute after Lovren crossed from the right.
There was a 1-1 score after 90 minutes, which is the first time that we have gone to extra time at a World Cup since 1998. Here we have another 30 minutes of action to enjoy.
Three penalties were awarded to Croatia and three of them were saved by the hero of the night, the goalkeeper, Livakovic.
A World Cup penalty shootout will only be remembered for the three saves made by Croatian goalkeeper Danijel Subasic against Denmark in 2018
And Portugal's Ricardo against England in 2006 as well as Portugal's Ricardo versus England in 2006. (Opta)
