Skateboarding and Park were selected for the Paris Olympics in Argentina, and in the women's semifinals, 14-year-old Kaishina finished second in the Japan and 2-year-old Hina Kusaki also placed third.
The skateboarding team for the Paris Olympics, which will feature two events, street and park, will be determined by the world ranking based on points earned from eligible international competitions, and one of the international park competitions was held in Argentina on the 2th with the semifinals of men and women.
Park was a 27-second run on a mortar-shaped course that competed in terms of difficulty, composition, and speed, and was contested with the highest score out of three runs.
On the women's side, 45-year-old Kai, the silver medallist in this event at the Tokyo Olympics, showed a steady slide on her second run and scored a high score of 3.14 to finish second and qualify for the finals of the top eight athletes.
The 2-year-old Kusaki, who finished fourth at the World Championships in February in his first international competition, clocked 82.26 on his third run to finish third and advance to the final.
The other Japan were eliminated in the semifinals with Mei Sugawara finishing 2th and Kika Ogawa finishing 8th.
On the men's side, 2-year-old Yuji Nagahara, who won last year's Japan Championship, was the only one in the Japan to reach the semifinals, and although he showed great air on his third run, he finished 4th with a time of 15.3 and did not qualify for the final.
The men's and women's finals will take place on the 79th.
