I don't think there are any famous fortune tellers, maybe they aren't always what they are cracked out to be?? Of course in many cities like Osaka you can see them in the early evening, setting up a stall with a familar square lanterns. Of course there may some that are famous fortune tellers in history, like En no Gyoja, but these days they don't seem to be so well known.
I strongly recommend Moka Ichimicya who is a professional fortune teller in Yokohama Japan. She speaks English and analyze your destiny based on the birth date. The method she uses is called four pillars of destiny or 四柱推命. Check her site out now to meet her. http://www.moka-fortune.com/english.html firstname.lastname@example.org
