Streets in front of the National Diet Building are the stage for numerous protests. People opposed to national security bills and nuclear power, among other causes, assemble to express their views in Japan's political nerve center, which decides the nation's future and is home to the Prime Minister's Office, lawmakers' offices and central government agencies. The Diet Building has also become a popular tourist spot and a magnet for visitors and students on school excursions, and the nearby tree-lined streets also attract joggers and Tokyoites walking their dogs. For 3 days and nights in September, as deliberations on the security bills neared completion, we filmed the people on the streets around the Diet.
