The Imperial Court is called Chotei (朝廷) which literally means the morning court; the politics, conferences and the like were held before noon from early in the morning in the Nara period when Taiho Ritsuryo (Taiho Code) was set up and the political system of the Imperial Court was established,
「朝廷」の言葉の由来は、大宝律令が成立し朝廷の政治体制が確立された奈良時代は、政治や会議等は早朝から始められ午前中に開かれていたことによる。
