I started the walk from Tokyo Station and walked along the moat of the Imperial Palace towards the National Diet Building (Parliament), and ended in front of the Prime Minister's Residence.
Inside the Tokyo International Forum. This building is one of the rare non-blocky buildings in Tokyo.
The view of the Shinkansen platforms of Tokyo Station.

The Ministry of Justice Building
Close up of the Diet building. Even though Japan is a free country, you can't walk up to the front gate of the building unlike in other countries. The front lawn/courtyard is fenced off.
