As part of the Meiji reforms, a single aristocratic class, the kazoku, was created in 1869 by merging the kuge (the court nobility in Kyoto, of which the kugyō was a part) and the daimyōs (the feudal land holders and warriors). In the 1870s, the organizational structure of the court itself was also modernized.
In the period after the Second World War, the kazoku was abolished, as a part of post-war Japanese reforms. The remaining political powers of the Emperor were transferred to the constitutional government of Japan, and the responsibility for state matters concerning the Emperor and the Imperial family was consolidated entirely into the Imperial Household Agency.
