On May 16 it was reported that Japan's Princess Mako, the eldest grandchild of Emperor Akihito, was soon to become engaged to a man who went to the same university in Tokyo.

It represents the first engagement among the four grandchildren of the emperor and Empress Michiko.

Princess Mako was born to Prince Akishino and Princess Kiko in October 1991. This photograph was taken the following month at the Imperial Household Hospital in Tokyo.

In August 2006, the princess was seen walking with a horse at a ranch in Vienna, Austria, where she was taking part in a home-stay program.

In October 2011, Princess Mako was seen after a formal meeting with her grandparents, Emperor Akihito and Empress Michiko, at Tokyo's Imperial Palace on the occasion of her coming of age.

In March 2014 the princess graduated from Tokyo's International Christian University, where she met her future fiance, Kei Komuro.

In the same month, she traveled to Sendai, northeastern Japan, with her father and met children who lost their parents in the March 2011 earthquake and tsunami disaster.
