Yukiko was a wonderful person to tour Tokyo with. She is easy to have a conversation with while walking around; more like touring the city with a friend, not someone you're just meeting for the first time. Yukiko recommended the right mix of sites to interest my husband and I as well as our 7 year old (the ninja experience was a hit and he can't stop talking about it). She was very prepared and gave us brief background history on the various sites we visited, which we really appreciated. I highly recommend a tour with Yukiko.
