共産主義思想はいつ日本に流入した？
Socialist thought in Imperial Japan appeared during the Meiji period (1868–1912) with the development of numerous relatively short-lived political parties through the early Shōwa period. Left wing parties, whether advocating socialism, Marxism or agrarianism, provoked hostility from the mainstream political parties, oligarchs and military alike, and many were either banned or went underground soon after formation. Although occasionally winning a seat in the lower house of the Diet of Japan, left-socialist parties played little role in the government of the Empire of Japan.
