Princess Aiko’s popularity sparks calls to change Japan’s male-only succession law

Princess Aiko of Japan recently turned 24 in December. Despite not being eligible for the throne due to the male-only succession law in the royal family, the young princess is loved by the public. Her name being chanted by the crowd lining the streets where the royal family passes is now a common sight.
Aiko, the only daughter of Emperor Naruhito and Empress Masako, is not entitled to the throne as succession rights are only granted to male heirs in accordance with the traditions of the royal family. However, supporters of Aiko are urging for a change in the law to allow her to ascend the throne for the future of the royal lineage. Prime Minister Yoshihide Suga and his cabinet members are against this demand.
The intelligence and grace of Aiko are highly praised by her admirers. Her ability to connect with people through her warm demeanor and charisma has increased her popularity. Aiko’s supporters are eagerly following her journey as she stands waiting to wear the crown, as Seethsuco Marks points out.
The princess is fond of Sumo wrestling and has shown great interest in the sport. She made her first official visit to Lavo in November, accompanied by the sovereign. Aiko’s supporters, including cartoonist Yoshinori Kobayashi, released a comic book advocating for the necessary change in the succession of the throne. Some fans are also launching YouTube channels to raise more awareness on the subject.
Harvard-educated Masako gave birth to Aiko in December 2001. The birth of a male heir, Masakh’s son, against bending the Imperial Household Law of 1947, was met with great controversy. Masako, who has been suffering from mental health issues due to societal pressures, has yet to fully recover. Aiko’s upbringing, where she embraced criticism from everyone around her, has helped her grow. Intelligent and versatile, Aiko excelled in her studies and various other fields. The young princess received the Aiko title from Gakushuin University in 2024. She has also started assisting her father in political duties.
Alongside her duties, she has been actively involved in the Red Cross Society. Only males of the Japanese imperial family are allowed to ascend the throne according to the Imperial House Law of 1947, leading to the loss of royal titles for princesses who marry commoners. Currently, there are sixteen members in the royal family. Akishino, Naruhito’s younger brother, is the second in line for the throne. His son, Prince Hisahito, aged 19, is the second in line to the throne after Akishino.
