the turn of the century, these restrictions imposed by the Allies had resulted in a situation where the dynasty came perilously close to extinction. Emperor Emeritus Akihito (eldest son of Emperor Shōwa) had only two sons: Emperor Naruhito and Fumihito, Crown Prince. The younger son, Prince Fumihito, was the first to marry, and he soon became the father of two daughters, Princess Mako (b. 1991) and Princess Kako (b. 1994), but he had no son until 6 September 2006, when his wife gave birth to Prince Hisahito. Akihito's eldest son, Naruhito, who married in 1993, did not become a father until 1 December 2001, when his wife gave birth to a daughter, the Princess Aiko. Naruhito and his wife received their child with great joy, since they had almost despaired of parenthood. However, the birth of the princess opened the question of the succession to public debate, because Naruhito's wife, who had suffered a miscarriage previously, and was very close to forty years of age, was unlikely to bear further children. Akihito's brother, Masahito, Prince Hitachi has no children at all. The two other collateral members of the Imperial Family also had only daughters: the late Prince Tomohito of Mikasa had two daughters, Princess Akiko (b. 1981) and Princess Yōko (b. 1983); the late Norihito, Prince Takamado had three daughters, Princess Tsuguko (b. 1986), Princess Noriko (b. 1988) and Princess Ayako (b. 1990). Prior to the birth of Prince Hisahito in 2006, no male heir had been born into the Imperial Family in nearly 41 years. Male members of the imperial family Order of succession Debate In the early 2000s, the succession controversy emerged as a political issue. The Asahi Shimbun published an editorial in May 2006 suggesting that the current system was unsustainable. In an Asahi Shimbun survey in March 2006, 82% of the respondents supported the revision of the Imperial Household Law to allow a woman to ascend to the Imperial Throne. Then Prime Minister Junichirō Koizumi also strongly supported the revision, pledging to present a bill to the 2006 session of the parliament. Some conservative lawmakers opposed Koizumi and said the debate was premature. The current emperor's cousin, Prince Tomohito of Mikasa, also opposed the proposal, saying that the official male members of the Japanese imperial family might take up concubines in order to produce male members because it was previously possible for a male illegitimate child
