Aaron Wolf won the men's 100-kg division at judo's world championships on Saturday, while compatriot Sara Asahina settled for silver in the women's over-78-kg class.
As two Japanese judoka were eliminated in the second and third rounds of the men's over-100-kg category, the country ended the individual competitions with seven gold medals, four silvers and one bronze from 14 divisions combined for both genders.
Japan tied the second-most golds it has won at a world meet, excluding the openweight categories, since the men's and women's contests were merged in 1987, one less than the eight it bagged at the 2010 championships in Tokyo.
