Great Britain have made a dream start to the women's hockey tournament, leading Japan 4-0 at half time.
Two goals from Alex Danson (6) and (27) and further strikes from Sarah Thomas (22) and Sally Walton (26) meant Team GB went into the break four goals to the good.
Team GB could not have wished for a better start to their Group A match at the Riverbank Arena as they look to qualify for the knockout stages.
