.Ana Maria Naimasi scored the opening try from a Talei Wilson offload before Younis Bese scored back-to-back tries.

Minutes before halftime, TMO denied a try to Japan from Chiharu Nakamura because she failed to ground the ball on the try-line.
Japan was awarded a scrum which Marin Kajiki fed and gave the ball away to Michiyo Suda, who barged over the Fijian defence to score a converted try.
Fijiana led by 21-7 at the break.
The offloading queens of Fiji continued with their impressive performance in the second half with Lavenia Cavuru scoring a back-to-back try from Ilisapeci Delaiwau’s set-up and breaking from a Japanese tackle.
Cavuru slotted both conversions for a 35-7 lead before they were reduced to six players when Uluinasau was sin-binned for a foul play.
Despite a player down, Japan failed to take advantage and knocked the ball forward which gave a penalty play to Fiji and Wilson extended their lead with a consolation try to seal the win.
Australia on the other hand defeated Great Britain 19-0 in its semifinal clash.
Fiji will face Australia at 6.22pm.
