[4] The Princess graduated from the International Christian University in Mitaka, Tokyo, on 26 March 2014 with a bachelor's degree in Art and Cultural Heritage.

[15] In 2011, Princess Mako came of age and was conferred Grand Cordon of the Order of the Precious Crown on 23 October.

[30] The wedding was originally expected to take place in November 2018,[31] but it was postponed after media reports of Komuro's mother in dispute with her former fiancé over ¥4 million ($36,000).

[30] On 26 October 2021, Princess Mako officially married Komuro following the submission of their marriage document at the local ward office.

[36] She is the first female member of the imperial family to forgo an official wedding ceremony and a gift of money from the government.

[38] For this reason, Mako moved to her own residence in the Shibuya district in Tokyo while awaiting her passport issuance and US Visa.

[40] Kei Komuro began studying at Fordham University School of Law in August 2018 and graduated with a Juris Doctor in May 2021.

[43] Weeks before her planned wedding, the Imperial Household Agency announced on behalf of Princess Mako that she had recently been diagnosed with complex post-traumatic stress disorder (C-PTSD) by the head of the quality assurance room of the NTT Tokyo Medical Center.

[44] The diagnosis determined that the C-PTSD originated during her primary high school years and continued due to strong criticism from imperial family members and the media.
