The Imperial Palace is the resident of the Emperor of Japan. It is built on the grounds of Edo Castle. The most convenient subway station is Tokyo Station.
The residential palace offers walking tours of select parts of its grounds. One could try his or her luck by queuing at around 9:00 am for a 10:00 am entrance or register and book a tour with the Imperial Household Agency online in advance. The latter method offers a guarantee entrance if the booking is accepted. They have daily quota of visitors for the free tours.
The tour lasts between an hour and ninety minutes depending on where one is taken as depending on the palace's requirements the tour may be curtailed and areas may be blocked.
The older parts of the palace feature the older parts of the former Edo Castle. The remnants of the old castle occupied by the shogunate of the 16th to 19th century are occasionally visible; however, most of the tour is an excursion through the outer buildings and offices of the current palace, the manicured gardens and the romantic, castle's gates and archaic bridges. One part of the garden resembles a giant bush, for example, but on closer inspection is shaped after a turtle, which is an omen of fortune and longevity in Japan. A part of the grounds was once called 'Fuji viewing' garden, but since skyscrapers of the business district have blocked the palace for years now, this has become an anachronism. The western grounds, which are near the 'eyeglass bridge and is actually on top of a massive underground parking lot, are what most people know of the castle as it is the site of the Emperor's New Year greetings that is broadcast on the news. The ceremonial hall/corridor is also where foreign ambassadors march through. On the day I was there two foreign ambassadors were carted with pomp and circumstance on the imperial chariot from Tokyo Station and, upon conclusion of their reception, back to the station. The ceremony was nice to see, but by the same token the tour was cut short.
The beautiful palace tour is free and available in Japanese, English and Chinese. These tours commence separately, but due to speed and logistics sometimes collide. If the explanations are unimportant to you or you speak Japanese I suggest taking the Japanese tour. The group is better behaved and more orderly. When I was there the Chinese tour group caught up with us and gave the palace security a lot of trouble as they strayed into forbidden areas and rushed for selfies and photographs to spots they were not allowed to go and were off limit thus annoying the guards and creating some fuss and upset the respective tour leaders.
Incidentally, the palace is surrounded by a beautiful garden and a moat. Tokyo Station nearby is a haven for food and pastry. One store was proudly selling Canadian maple syrup cookies made in Quebec. In particular, one store sells ekiben (station bento) from all over Japan, which means many regional meals and specialty train station food trays are on offer in that Tokyo location. The food should guide one's choice, but just for interest and cuteness sake two of the bentos are a Doraemon and a Bullet Train one. Try it.
Dining options are aplenty at Tokyo Station or walk ten minutes to the south (which is straight ahead as one exit's the palace's main gate) and the alleyways are full of dining options along the train tracks.
