The Ministry of Ceremonies (治部省 Jibu-shō?) (lit. the department of governance affairs) was a division of the eighth century Japanese government of the Imperial Court in Kyoto), and it is sometimes identified as the "Ministry of the Interior". This bureaucracy was instituted in the Asuka period and formalized during the Heian period. The Ministry was replaced in the Meiji period.
The ministry was organized to address the ceremonial aspects of the Imperial year, to manage the ceremonial nature of formal relations with China, Korea, and other nations, and to oversee the maintenance of Imperial tombs and mausoleums. The ceremonies of the Imperial Household evolved over time.

- maintenance of the roster of names of officials
- oversight of the succession and marriage of officials of and above the fifth grade of rank
- oversight of formalitie relating to deaths, funerals and the granting of posthumous rank
- management of the memorial activities which honor the anniversaries of the demise of a former Emperor
- monitoring and recording of the names of all the former Emperors, so that none of those names shall be used by any of the succeeding Emperors nor by any subject
- adjudication of disputes about the order of precedence of the various families 
- supervision of all matters relating to the music 
- registration of names of Buddhistic temples, priests and nuns 
- reception and entertainment of foreigners and managing to their presentation to the Emperor
