Hikaru Naomoto and Aoba Fujino scored two minutes apart in the first half to lead Japan to a 2-0 Women’s World Cup victory over Costa Rica on Wednesday, and the Japanese qualified for the knockout stage later when Spain beat Zambia. Japan and Spain — 5-0 winners over Zambia — were the first teams in the tournament to move on to the round of 16. Japan and Costa Rica kicked off in front of a sparse crowd of 6,992 at Dunedin Stadium, a huge differential from the record sales of over 1.5 million tickets for this year’s tournament.
