Hinata Miyazawa bagged her second brace of the Women's World Cup on Monday as Japan claimed a resounding 4-0 victory over Spain to top Group C with three straight wins.

Miyazawa's clinical finishes came on either side of her team's second from Riko Ueki as world No. 11 Nadeshiko Japan cruised to a 3-0 lead at the break against sixth-ranked Spain. Mina Tanaka buried a superb fourth goal eight minutes from time at Wellington Regional Stadium.

Japan, which has yet to concede a goal at the tournament, will face Group A runner-up Norway in the round of 16 on Saturday, when Spain takes on Switzerland.
