Completed in 1936, the National Diet Building is a prominent landmark in the government district, easily recognized by its terraced roof. The rows of ginkgo trees in front have made it a famous spot for autumn foliage, offering a striking contrast between the historic seat of Japanese politics and vibrant seasonal colors. The grounds are divided into north and south gardens: the north features a Western-style garden, while the south offers a traditional Japanese garden with an impressive multi-level stone waterfall—perfect for an autumn stroll.
