Why National Diet Building is special ?

The National Diet Building is the center of Japan's politics as it is the place where Diet sessions are held. The building is in Nagata-cho, Chiyoda ward, Tokyo, and features a pyramid-like tower in its center. It was completed in 1936 after 17 years of work involving a total of 2.54 million people at a cost of 25,736,000 yen.

The stately building is 206.36 m long and 88.63 m deep, with the central tower standing 65.45 m tall. Seen from the front, the building has a chamber for the House of Councillors on the right and one for the House of Representatives on the left. In the center hall directly under the central tower, the bronze statutes of Hirobumi Ito, Shigenobu Okuma and Taisuke Itagaki-credited with the formulation of the Constitution of the Empire of Japan (Japan's first modern constitution, also called the Meiji Constitution)-were erected to commemorate the 50th anniversary of the promulgation of the constitution. The central tower was the tallest building in Japan when it was completed.


What to explore at National Diet Building?

Groups of up to 10 people are allowed to look around the House of Councillors building without an advance reservation, visiting such places as the lobby for visitors, the chamber floor, the room built as a rest area for the Emperor, and the center hall. A referral from a House of Representative member is required to enter the lower-house building. In principle, the Diet Building is lit up from sunset to 10 pm every day. The practice started in 1990 to commemorate the 100th anniversary of the establishment of the Diet.

Quite a walk from the underground station but a very large and imposing building. You can go up 45 floors in about 20 seconds and on a clear day can see Mount Fuji their is a English speaking guide if you would like and she takes you around. A nice cafe at the top souvenir shop overall well worth a visit.
