National Diet Building

The stately National Diet (Parliament) Building is a must-see Tokyo tourist attraction. Standing three-stories high on Kasumigaseki Hill, this elegant building is the center of Japan’s parliament, or Diet. Admire its German-influenced architecture from outside or venture indoors for a free guided tour to learn more about its history and role in government.

The National Diet Building in Tokyo took 17 years to build, with construction finished in 1936. It stands 65.5 meters tall, and over 2.5 million people worked on its construction. All building materials were locally sourced, including the glossy marble interiors. A tall, pyramid-shaped tower is located in the center of the building, along with bronze statues of Japan’s founders in the palatial central hall.
Although you’ll need an invitation to tour the House of Representatives, free guided tours are available should you wish to visit the House of Councilors. You’ll get an inside look at the chamber floor, central hall, and even the Emperor’s rest areas – a remarkable addition to any Tokyo sightseeing itinerary.

Opening Times:
The National Diet Building is open Monday through Friday, between 9:00 and 16:00. It’s closed on Saturday, Sunday, and Holidays.
