Japan 3, Sweden 1
Sixth-ranked Japan started off their tournament with a hard-fought win over a Sweden club that enter the Olympics with their lowest ranking ever at ninth.

Akane Shiga fed Rui Ukita, who scored on a breakaway to make it 2-1 and Haruna Yoneyama added an empty-netter with a minute left to seal the victory.
