We had two tours with Yuki, one in Tokyo centre and one in Yokohama. On both occasions Yuki met us on time and with a big smile. We had exchanged e-mails prior to the tour so Yuki knew the sights we wanted to see. He then arranged the days so we saw everything we wanted. We went on the underground and the bus system and had two excellent lunches in traditional restaurants. Yuki was very knowledgeable and explained about the history associated with the sights. I would have no hesitation in recommending Yuki as a guide when you visit Japan.
