Riko is a very knowledgeable lady with a very friendly demeanor & good sense of humour as well as patience. She ensures that you get to do everything you have asked and offers alternatives if what you want is not available. She explains things in an easy to understand way and ensures that children are included in the tour by involving them. We not only learned about Japanese history and culture but also about what it was like to live in Tokyo (schooling, cars, metro system, shopping etc) and is honest about the "tackier" areas of the city. Riko was that good we were able to make our way across Tokyo ourselves on a different day using the railway as she had explained it so well! I would highly recommend Riko as a tour guide for Tokyo.
