Tokyo Station is located in Mauronouchi so the area is one of the first spots you will see if you are arriving in Tokyo by the Shinkasen Bullet train.

Located east of the station is the Tokyo International Forum, this impressive building serves as a group of halls and an exhibition space, the building is well worth a visit as there is a pretty good tourist information desk there.

Venture a couple of blocks west of the International forum and you will find huge grounds of the Imperial Palace surrounded by a moat. The palace is only opened on new years day and the Emperors birthday but the east and Kitanormaru are opened regularly with the latter being home to the martial arts hall known as Nippon Budokan.

The area is borded by the Tokyo Station on the east side while the Kudanshita Subway Station is located on north side of the Kitanormaru gardens near Budokan. Marunouchi is only about 4 blocks south east from the Ginza area and is well worth a stroll there.
