The center of Japanese politics, the National Diet Building houses both chambers of the National Diet, Japan’s legislature. The House of Representatives meets in the left-wing and the House of Councillors meets in the right. One of the city’s most impressive buildings—constructed almost entirely of Japanese materials—and featuring a pyramid-shaped dome in the center, also makes it appealing to visitors.
