As of the early 21st century, Japan's succession law prohibits a female from ascending the throne. With the birth of a daughter as the first child of the then-Crown Prince Naruhito, Japan considered abandoning that rule. However, shortly after the announcement that Princess Kiko was pregnant with her third child, the proposal to alter the Imperial Household Law was suspended by then-Prime Minister Junichiro Koizumi. On 3 January 2007, as the child turned out to be a son, Prime Minister Shinzō Abe announced that he would drop the proposal.
