Censorship in the Empire of Japan

Censorship (検閲, Ken'etsu) in the Empire of Japan was a continuation of a long tradition beginning in the feudal period of Japan. Government censorship of the press existed in Japan during the Edo period, as the Tokugawa bakufu was in many ways a police state, which sought to control the spread of information, including Christianity, the influx of Western ideas, pornography and any political writings critical of the shōgun and government.
