Yuko is everything you want in a tour guide: she spoke perfect English and was very friendly, personable, and flexible. She was very informative and knowledgeable about her city and, all in all, a very down to earth and pleasant person to spend the day with. We very much enjoyed being with her and highly recommend her for anyone wanting to explore Nagasaki. Let me add that it rained all day without stop — and we still enjoyed our day with Yuko!
