THANK YOU! On June 30 - July 2, 2017, ISKF Colorado had our camp at Snow Mountain Ranch. Our guest instructor was Sensei Yaguchi. We had a wonderful time! Although many pictures have already been posted in social media, we have more pictures. Click here.

On December 17, 2016, Sensei Yaguchi had his last seminar at Lone Tree Recreation Center. With this seminar Sensei had finished all his official instructions. He retired from his organizational duties after over 60 years. As he is a legendary icon in Karate world, we will surely miss his presence and instructions.
