This was our first trip to Japan. We only had 5 days, 1 being taken up by a visit to Disney Sea, so our explorations were not as extensive as we would have liked. We used the metro system extensively and found it to be very efficient and with a bit of study, not difficult to navigate. Also the daily temperatures ranged from 14 – 18 C and cooled down more in the evenings which did curtail some of our planned activities. We still got a good feel of the city and want to experience more so another trip will definitely be in our future. We also took an afternoon/evening trip down to Yokohama by rail. It had a different feel than Tokyo and we enjoyed our brief visit there as well.
