Yumi is a lovable, sympathetic person with an acceptable English. If she has a deep knowledge of the history & culture of Japan - it was not apparent during our trip to Tokyo. The schedule she prepared was OK. (As far as I can judge). Her warm personality more than makes up for the a/m shortcomings.
TOUR GUIDE RESPONSE: Dear Dan, thank you very much for hiring me as your guide in Kanto region for your trip and feedback. Yes, I will study deeply and improve more about culture and history of Japan, especially in philosophical perspectives as you suggest. I wish your good health and happiness for all of your family, and success of your life. Sincerely, Yumi
