Princess Aiko, the princess of Emperor Naruhito, might be able to give birth to a woman successor. The 23-year-old lady is well-known and of clear line of descent in Japan, but the law forbids her from becoming an queen.
She has been deemed a potential leader to the king. Nearly 80 % of ( Japanese ) people support the choice, according to Daisaburo Hashizume, a professor at Shizenkan University who has been given a special appointment.  ,
However, there is a “hard line” to cross because extremely conservative loyalists oppose the change to the Imperial House Law.
The time is running out. Princess Aiko will also have to leave the royal household if she marries.  ,
The government is considering its options, but it’s not certain whether politicians will soon come to a decision on a new legislation.
The royal family, whose background is thought to date back some 2, 600 years, perhaps vanish if they don’t act quickly, according to observers.
The royal family’s major symbolic role in Japan will change a lot as a result.
