Haruna Asami scored an ippon victory against Tamami Yamazaki in the women's 48-kg final to capture her first title at the All-Japan invitational weight class championships on Saturday.

London Olympic silver medalist Riki Nakaya won his second consecutive title at 73 kg at the tournament, which doubles as the final qualifier for the world judo championships in Rio de Janeiro this summer.

The 25-year-old Asami scored yuko points with an outer-leg sweep and body drop against Yamazaki before deploying a "seoinage" shoulder throw to end the match after 3 minutes, 33 seconds.
