History of Japan's Imperial Family
In 1947, after World War II, the rules for who could be part of the Imperial family changed. Membership was limited to male descendants of Emperor Taishō. Women who married someone outside the Imperial family were no longer considered members.
At that time, eleven branches of the Imperial House were removed.
The Imperial Household Law (皇室典範, Kōshitsu Tempan) is a special law that explains who is an official member of the Imperial family (皇族). This includes:
- The Empress (皇后, kōgō)
- The grand empress dowager (太皇太后, tai-kōtaigō) (the great-grandmother of the current Emperor)
- The empress dowager (皇太后, kōtaigō) (the grandmother of the current Emperor)
- The Emperor's sons and grandsons born in the male line (called 親王 (shinnō)) and their wives (called 親王妃 (shinnōhi)).
- The Emperor's unmarried daughters and unmarried granddaughters born in the male line (called 内親王 (naishinnō)).
- The Emperor's other male descendants in the male line (called 王 (ō)) and their wives (called 王妃 (ōhi)).
- The Emperor's other unmarried female descendants in the male line (called 女王 (Joō)).
