I think this tour is a gem to explore inside an old town of Tokyo, which you might not be able to do it yourself without a guide. Our guide is very informative. However, there is a requirement I'd like to suggest for people who are willing to join. You should have no issues related to walking fast, such as knee issues or else, because this tour is a walking tour and required to visit many places in complex small walking roads including uphill and downhill. Otherwise, you may not be able to catch up with the group. Besides that, I strongly recommend this tour.
