Permitting less fouls, Japan played stunning footy getting the Brazillians into a defensive mode.
Japan blazed through with several attempts, from striker Yuka Momiki that got countless wide shots from penalties before flanker Miyabi Moriy cracked the score board open in the seconds of the four minutes extra time before the break.
Brazilians stiff defence was not strong enough as Japan maintained ball possession and limited their fouls to pull in front.
It will be a deciding second half as the win for tonight determines the fate of both teams.
