Defending champion Japan had to make do with a share of the points as it was held to a 0-0 draw against North Korea in its second game of the women's competition at the East Asian Cup on Thursday.
Striker Yuki Ogimi twice went close to marking her 100th national team appearance with a goal in steamy conditions at Hwaseong Stadium, but the well-organized North Koreans stood firm and the result leaves both teams with four points.
Women's world champion Japan opened with a 2-0 win over China on Saturday and North Korea beat South Korea 2-1 on Sunday.
