National Diet Building

The National Diet Building 国会議事堂, (Kokkai-gijidō) is the centre of the Japanese Government in Tokyo, and is where the country's parliament meets. Owing to its importance in the country's affairs, it features in many different films.

Gojira
After the residents of Odo Island and an expedition force led by Kyohei Yamane find Godzilla after he rises behind the island's hill, some of the residents and the expedition force return to Japan and tell the government what they had found from within the Diet Building. It is here where Yamane provides his theory as to how Godzilla came to exist. Later, during Godzilla's attack on Tokyo, he travels towards the Diet Building, and walks straight through the west wing, tearing large parts of the building down as he moves through it.

King Kong vs. Godzilla
After menacing Tokyo, King Kong arrives at the Diet Building and climbs it, somehow not breaking the building in the process. The J.S.D.F. roll in, and prepare to fire at the Giant Ape, but relent after it is discovered that Kong is holding Fumiko in his right hand. It is then that they decide to fire rockets containing Soma juice into the air while playing recordings of the Farou Island natives. King Kong falls asleep, freeing Fumiko and allowing the J.S.D.F. to take him to Godzilla via a series of balloons and a pair of Sikorsky H-19 Helicopters.
