Braids 2019 at Iga City will provide you a deep knowledge of Kumihimo through discussions and criticism by the Iga Kumihimo artisans and of course many types of Kumihimo tools as well. Immediately after Braids 2019, the Tenjin Festival will be held from 19 to 20 October so you may wish to plan this unique event into your itinerary.
This promises to be a wonderful event. I had an amazing time in Tacoma in 2015 and I am looking forward to Japan in 2019.
