According to the Emperor Abdication Law, the range of 皇族 exclude the Emperor Emeritus (上皇, jōkō) and include the Empress Emerita Empress Emerita (上皇后, jōkōgō). The Empress Emerita is seen as equivalent to the Empress Dowager, thus ranking below the Empress.

The order of precedence in Japan does not list male and female members separately.

The Imperial Household Law (1889) did not make specific regulations regarding the order of precedence of princes and princesses. However, according to custom, the princes are ranked in accordance with their positions in the line of succession to the throne. The consorts rank behind their husbands. The blood princesses are ranked as if they are princes and siblings are ranked in terms of seniority.^[4]
