Kanpō (, literally "Official report") is the official gazette of the Japanese government. Its official publication started in 1886, from the National Printing Bureau of the Ministry of Finance.
Japanese people historically relied on the kōsatsu, a wooden plaque placed at shukuba and other important places, to learn of proclamations made by either the shogun or the local daimyo. As the literacy rate improved and the modern nation emerged under the Meiji government, the kōsatsu was abolished in 1873 and eventually replaced by the Kanpō, the Japanese government gazette, which is now available on the Internet.
