Kokkashugi (国家主義) was the ruling ideology of the Empire of Japan, particularly during the first decades of the Shōwa era. It is sometimes also referred to as Emperor-system fascism (天皇制ファシズム, Tennōsei fashizumu), Japanese-style fascism (日本型ファシズム, Nihongata fashizumu) or Shōwa Statism. Developed over time following the Meiji Restoration, Kokkashugi incorporated ultranationalism, traditionalist conservatism, militarist imperialism, and a dirigisme-based economy.
