Hello Nobu-san,
My family and I all agreed that you were an outstanding tour guide for our stay in Kyoto! We were also impressed that you are only one of 5 people in Kyoto who has a license in being both tour guide and taxi driver. We hope you will continue to give people such a wonderful experience in learning about your city. I will refer your name and email address to any possible friends and family who plan to travel to Kyoto and might be interested in getting a taxi tour like us.
And remember that if you and your family ever have a chance to visit Honolulu, please let us know.
We would enjoy meeting you again.
