This time, the 18-year-old Japanese kept his nerve to top all four boulder problems and win with 99.7 points, edging Lee by just 0.4."I'm really happy," said Anraku. "The routes were tough, but I managed to top all four, and that made me feel like I've grown,"said Anraku."I was nervous watching the others do so well, but once I got on the wall, I focused on enjoying every climb," the Japanese added.Following his Olympic disappointment, Anraku said he had spent the off-season training to address his weaknesses. "There were a lot of things I couldn't do last year. But today, I overcame many of them. My goal now is to win gold at the World Championships in September."Lee, who had also topped all four problems but needed more attempts, settled for silver with 99.3 points. Japan's Meichi Narasaki took bronze.The boulder discipline adopted a new scoring system this season, awarding 25 points for a top, 10 for reaching the zone, and deducting 0.1 for each failed attempt.In the women's final, Slovenia's two-time Olympic champion Janja Garnbret was absent, leaving room for fresh faces. Sanders seized the opportunity to take her second career World Cup gold, ahead of France's Oriane Bertone and Erin Mcneice of the United Kingdom."I definitely wasn't expecting it," Sanders said. "After the first boulder I was frustrated, and the second didn't go well either. But the third lightened my mood, and on the fourth I just gave it everything to get to the zone."Annie Sanders celebrates after the women's boulder final.

"There's still a lot to improve, but compared to before, I don't feel lost out there anymore."Xu Ziqi in action during the men's boulder event.
