We met Mayumi on our first full day in Tokyo. We could not have asked for a more patient, kind, knowledgeable, & energetic guide to introduce us to the biggest city in the world. She asked about our interests and then designed an itinerary around our interests while taking the time to show us how to navigate the multiple subways lines. Her insight as a local to the area was invaluable, and we also greatly enjoyed her company. We feel we not only learned a great deal about the city, but we made a new friend in her as well. We cannot say enough good things about this experience. She made all the difference in the world for us in our first experience with Tokyo, as we wanted to make the most of the short week we were going to be visiting. Highly recommend Mayumi!
