Emperor Akihito and Empress Michiko with their family in November 2013
Members of the Imperial Family show themselves to the general public during celebrations for the new emperor's enthronement. Emperor Emeritus Akihito and Empress Emerita Michiko are not present (4 May 2019).
Article 5 of the Imperial Household Law (皇室典範 Kōshitsu Tenpan) defines the Imperial Family (皇族 kōzoku) as the Empress (皇后 kōgō); the Grand empress dowager (太皇太后 tai-kōtaigō); the Empress dowager (皇太后 kōtaigō); the Emperor's legitimate sons and legitimate grandsons in the legitimate male-line (親王 shinnō), and their consorts (親王妃 shinnōhi); the Emperor's unmarried legitimate daughters and unmarried legitimate granddaughters in the legitimate male-line (内親王 naishinnō); the Emperor's other legitimate male descendants in the third and later generations in the legitimate male-line (王 ō) and their consorts (王妃 ōhi); and the Emperor's other unmarried legitimate female descendants in the third and later generations in the legitimate male-line (女王 joō). In English, shinnō and ō are both translated as "prince" as well as shinnōhi, naishinnō, ōhi and joō as "princess".
After the removal of 11 collateral branches from the Imperial House in October 1947, the official membership of the Imperial Family has effectively been limited to the male line descendants of the Emperor Taishō, excluding females who married outside the Imperial Family and their descendants.
