Dee Chen in the UK is a shihan with the Birankai, though it's not clear whether that is the same as being an Aikikai Shihan.
Dear Mr Megann,

The presentation was made by Chiba Sensei,8th dan Shihan, Technical Director ,Birankai International.
I also sent you a email to your dojo.Unfortunately the mail did not get through .
