Japan for non-Japanese

I showed a vistor from the states around Tokyo today. I took her to Shibuya and Harajuku. She didn't seem to be interested in Japan's old stuffs (kabuki, sumo, shrine...) and very new stuffs (animé, costumes,...). Therefore, I felt difficulty showing her around. Even if you have a good command of English and you are Japanese, it is hard to teach others about Japan.
