Imperial_Household_Agency

The Imperial Household Agency (宮内庁, Kunai-chō) (IHA) is an agency of the government of Japan in charge of state matters concerning the Imperial Family, and also the keeping of the Privy Seal and State Seal of Japan. From around the 8th century AD, up until the Second World War, it was known as the Imperial Household Ministry (宮内省, Kunai-shō).
The Agency is unique among conventional government agencies and ministries, in that it does not directly report to the Prime Minister at the cabinet level, nor is it affected by legislation that establishes it as an Independent Administrative Institution.
