Masahiko was very accommodating since we had to change days due to our flight delay. He was also very nice to meet us at our hotel and printed up a sheet with the name of our hotel in Japanese so we could get back on our own after he dropped us off at the the Robot show on Shinjuku. His tour needs more than 2.5 hours to see all the sights. Unfortunately, we weren't able to enjoy golden gai--we walked quickly through it. It would have been interesting to go into one of the taverns to see what's it like. His pace was very fast and we sometimes had a hard time keeping up. His English was okay.
