Emperor of Japan
Until the birth of a son to Prince Akishino on September 6, 2006, there was a potential succession problem. No male child had been born into the imperial family since Prince Akishino in 1965. Following the birth of Princess Aiko, some felt they needed to change the current Imperial Household Law to allow women to succeed to the throne. In January 2005 Prime Minister Junichiro Koizumi created a group of judges, university professors, and civil servants to study the problem.
