The imperial residence is the place where the emperor of Japan lives. There is a moat outside. There are 3000 pines in it. It is one of the two green spaces in the city. We go in from the east gate and look at the double bridge far away. It is said that only two days of the year are limited. One is the birthday of the emperor and the other is the National Day of Japan. Now there is the square, where many local people have picnics and sports. It happened that I met the change of posts, but there was no special ceremony like the one I imagined. It was simple. So many stones on the ground are said to be anti-theft, because there is a sound when you step on them. There are two swans in the moat who have not been there for a long time.
