We used taxi driver/tour guide Naoki Doi during our recent trip to Kyoto. I want to echo how great he was. His English and his knowledge of the places he took us was excellent. He kept my 2 teenage girls engaged for the 6 hours we booked with him, no easy feat. I highly recommend him to anyone considering a guide in Kyoto. We found having a guide very helpful as our time was limited and public transportation, while available, is not as easily accessible or user-friendly in Kyoto as it is in Tokyo.
