Princess Mako, a granddaughter of Emperor Akihito and Empress Michiko, said Monday that studying at the University of Edinburgh was "very fruitful."

The 21-year-old princess, the eldest daughter of Prince Akishino and Princess Kiko, told reporters on wrapping up her studies at the university, "I had lots of opportunities to speak English and I think this experience will be useful" in the future.

Princess Mako, who studied art history and other subjects at the university starting last September, was also taken around a campus library Monday by Timothy O'Shea, principal of the university.

The princess went to study at the University of Edinburgh during her junior year at International Christian University in Tokyo.

During her nine months in Scotland, she paid a brief visit to art museums in Paris as part of her scholastic activities and traveled around Britain on her days off, the Imperial Household Agency said.

Before flying back to Japan this summer, she is scheduled to travel to various locations in Europe to increase her knowledge of foreign cultures and people, the agency said. She is scheduled to re-enroll at ICU upon her return.

Her father is the younger son of the Emperor and Empress.
