Mayumi san was awesome! She is very friendly, knowledgeable and fun to be with. We had a big day going to both sides of Tokyo, east and west, but we accomplished it in 8 hours because of her efficiency. In these 8 hours we learnt a lot about the history, religion and culture of Japan. She recommended other places for us to visit in our time and went out of her way to help my children buy some manga books. She also helped us get back to our hotel when she found us lost and disoriented with directions near Sunshine City. I highly recommend her as a guide.
