Princess Mako, the niece of Emperor Naruhito, and her long-time boyfriend, Kei Komuro, will tie the knot by the end of the year and start a new journey in their lives after a nearly four-year delay since the initial announcement of their engagement.

All eyes are now on Komuro, the princess’s college classmate, who returned to the capital on Monday to start preparations for the wedding. It is his first visit to Japan since he left for New York in August 2018 to study at law school.

To the surprise of the Japanese public, Komuro was sporting longer hair tied into a ponytail when he departed from JFK Airport on Sunday.
