Doshu Yoshigasaki graded four people to Ninth Dan, three from Italy, and Sensei Burgess. These Ninth Dans are arranging a seminar next year in Italy to commemorate the passing of Yoshigasaki Sensei. The plan at the moment is that the majority of the seminar will be taught by the four Ninth Dans but an opportunity will be given for younger instructors to teach a small portion of the course as well.
The exact venue and other details are still being worked out. Of course, this is all subject to how things are with the pandemic come February.
