The basics

The interior of the National Diet Building is decorated with cultural artifacts and artworks—such as bronze statues of the men credited with formulating Japan's first modern constitution—and extensive murals inside the Central Hall. The building sits on land once inhabited by feudal lords, and was once the home of the chief minister of the last shogun, giving the spot even more historical significance.

Tours of the House of Councillors are sometimes offered for groups of up to 10 people. To visit the lower house, a House of Representatives member is required as an escort, and so prior arrangements are necessary. If you are more interested in just seeing the exterior, join a sightseeing tour of Tokyo that passes by or stops at the National Diet Building—that way you can check off multiple attractions in one day.
