Keiko was our ideal guide, providing lots of information without us needing to ask. Her knowledge of history is wonderful. Exactly what we wanted. She even brought photos of the Imperial family and illustrations of what Tokyo looked like in the past. She guided us seamlessly around Senso-ji Temple, it's market street and Imado Shrine. Imado was a new one for her but Keiko still provided us plenty of information about it. We had four different guides for our 10 day trip to Japan and Keiko was by far the best!
