Me and Emelie visited the east gardens of the imperial palace on our first proper day in Tokyo. Most of the imperial palace grounds are off limits but the east garden is open to the public, free of charge. It is situated pretty much in the heart of Tokyo, near the central station, but even if is surrouded by walls of skyscrapers you have the most serene feeling walking around in there. Maybe it is because no subway lines run underneath the palace or the park. My favourite part was stalking and spying on the Japanese tourists, the are just ... delightful to observe. Emelies favaourite part was probably seeing the koi fish in the pond.
