Sorato Anraku led a Japanese men's podium sweep at the sport climbing lead World Cup in China's Wujiang on Sunday, while reigning world champion Ai Mori took out the women's competition.

The 16-year-old Anraku claimed his third straight lead World Cup win after reaching 39+ in the final, beating Shion Omata on 30+ and Taisei Homma on 26+ in the final meet of the season.

Anraku, this year's overall bouldering winner, comfortably wrapped up the lead title to become the first man to win both in his first senior World Cup season.

Mori reached 36+ for her win on the day, followed by Austria's Jessica Pilz who ended on 31+ and Japan's Natsuki Tanii on 26+.

Mori finished fourth overall for the season.
