The 29-year-old granddaughter of former Emperor Akihito and Komuro first announced their marriage in 2017. But the wedding day was postponed following a financial dispute between Komuro’s mother and ex-boyfriend.
Princess Mako and Komuro met on their way to International Christian University in Tokyo in 2012.
Prior to being introduced as a royal woman, Komuro was better known as the “Prince of the Sea,” after appearing in a tour of the coastal city of Fujisawa, south of the capital.
Japan’s imperial law applies only to heirs who are allowed to sit on the throne.
If some unmarried princesses of the family marry ordinary people, they too may lose their kingship. That could leave the royal family without enough members to do its most important work.
