Princess Aiko marks 11th birthday
Princess Aiko, the only child of Crown Prince Naruhito and Crown Princess Masako, and granddaughter of Emperor Akihito and Empress Michiko, turned 11 on Saturday.
Aiko, who is a student in the 5th grade at Gakushuin Primary School in Tokyo, plays basketball at her school and is studying English, the Imperial Household Agency said.
The princess stayed away from school for a long time in 2010 after reportedly encountering rough behavior by boys in her grade. She had to be accompanied by her mother, Crown Princess Masako, to school for about 18 months, but has been going by herself this year.
