The '' or 'Chancellor of the Realm' was the head of the ''
Daijō-kan'', or Department of State in
Heian Japan and briefly under the
Meiji Constitution. The position, along with the rest of the ''Daijō-kan'' structure, was initially created by the
Code of Taihō in
702.
The Chancellor presided over the Great Council of State, and controlled the officers of the state, in particular the
minister of the left (左大臣, ''Sadaijin'') and
minister of the right (右大臣, ''Udaijin'') , as well as four great councillors and three minor councillors. The ministers in turn controlled other elements of the government.
As the
Fujiwara clan, which dominated the
regency, gained influence, the official government offices diminished in power. By the 10th century, chancellors had no power to speak of unless they were simultaneously regent, or otherwise supported by the Fujiwara. Although the position continued in name until 1885, by the beginning of the 12th century, the office was essentially powerless, and was often vacant, as the regents, who sometimes acted as minister of the left or right, held all the administrative power over the government. It was briefly resurrected under the
Meiji Constitution with the appointment of
Sanjo Sanetomi in
1871, before being abolished completely in
1885.
