Kuroha Takes Triple Crown with Win in Pan-American Senior Katas

Miyuki Kuroha, a native of Ibaraki Japan and 4th Dan student of Sensei Yutaka Yaguchi at the ISKF Colorado Dojo located on South Broadway in Denver, won 1st in Kata in the Women's Black Belt 45 years and up category ( Senior division ), at the Pan-American Karate Championships in Mexico on Sunday, August 17,2014.

The victory was especially significant as it came after similar victories in kata in the ISKF U.S. Nationals and World Tournament ( known as the Shoto Cup). According to Sensei Yaguchi, the three events are the most important ISKF tournaments, and Kuroha, who represented the USA, may have been the first person ever to win the Triple Crown and take first in all three events.

The win came only three weeks after Kuroha fully from health problems that prevented her from training for many months.

The victory in Mexico was a very close thing. In the final round, Kuroha competed against Amy Okazaki, also of the USA, who performed the kata, Chinte while Kuroha performed Niju Shi Ho. The performances were judged a tie. 'I was surprised," said Kuroha."Amy did her kata very well. I thought she had won.''

In the second round, Kuroha performed Bassai Sho while Okazaki performed Jion. This time, Kuroha felt confident that she would win. She received a score of 21.9, which was enough for the win.

Asked whether she favored any particular strategy, Kuroha said only 'I believe in myself.'

Behind Kuroha and Okazaki, third winners were Marcia Ransom of the USA and Dawn Rivard of Canada.

Jeff Hermans, an ISKF Mountain States member from Vail, was part of the team that took 1st in Men's Senior Team Kata.
