As we were walking up to Kiyumiza-dera Temple, which is basically a pedestrian mall filled with tourist stuff. There was a store that catered to Japanese celebrity type items. No dice, simply the young clerk giving me the X sign with his hands. Which to me was about the only off putting thing in Japan, but that seems to be a young people thing and they can be just as annoying no matter where in the world they are. :) Now my last chance was the final leg of the trip back in Tokyo.
In Tokyo stayed at the Marriott in Ginza (great location, three major subway lines right outside the door) and then time was running short. Luckily the plucky hotel staff helped me out and pointed me to Yamano Music on Chuo Dori. A five minute walk from the hotel (well for me... the advantage of being tall). So we stopped by while looking for dinner and I met with some success.
