The buildings on this site were built and paid for by several 13th or 14th century Shogun and their men. To mark the areas built with their money and men, an identifying symbol was carved into a wall. Can you see the little circle with the lines across it?
There were lots of buildings with lots of purposes, historic and current, but we didn't actually see where the Emperor's family lives. I just know that you can't see it from outside the gates.
The day with the group ended after the second tour and Allan and I walked to Ginza. Ginza is the 5th Avenue of Tokyo, great shopping. Allan didn't buy me the $3,000 coat that I really liked.
We were looking for dinner when we saw this guy. It was December 24th. He was cooking in one of the cafes in the path to the train. We dubbed him 'Ninja Santa'.
