We really had a great time touring Akihabara, Kappabashi (Kitchentown) and Imperial Palace with Sayoko. She helped us with getting lesser price at one of the flea market on our way to Akihabara. She brought us to Kappabashi and we found a very good knife shop there. She even tried to find us a proper place for us to pray and eat halal food. She likes to make new friends and want to know you more. She is flexible with time and did not mind to extend/change her plan to accommodate us. My daughter really liked her a lot and made and impact on our stay in Tokyo. We were very comfortable when touring Tokyo city with her.
I highly recommend Sayoko :)

Kazu did a great job and helped us a lot in exploring Ginza and Tokyo Skytree area. Although we did not get the chance to go to the viewing deck in the Skytree (the queue to buy entrance tickets was very very long) but he gave us alternative to view the Tokyo city at the 30th floor in the next building (its free of charge). He also helped us find Halal food and patiently waited for us while we went shopping like crazy in Uniqlo (unbelievable price!). He picked us up at the hotel lobby and sent us back to the same spot although its already more than 7 hours guided tour. I strongly recommend Kazu to you!
