It was 2005 when Ali sensei informed Dojo member that one his best Japanese friends and his master are coming to Iran. Takeshi Kasuda sense, the friend, came, but Ishigaki Shihan couldn't make the trip. Now we are happy to understand that Kasuda Sensei has promoted to 6th dan and entitled "Shihan". Picture below, Kasuda Shihan in brown in a dojo which Ali sense has practiced a lot.
