Masako
Meaning
child of correctness and elegance (kanji-dependent); famously borne by Empress Masako of Japan
The story
Masako is a Japanese name whose meaning shifts with the kanji chosen to write it, most often read as a child of correctness and elegance. Its most famous bearer is Empress Masako of Japan, who came to the role by one of the most discussed paths in modern royalty: Harvard-educated and a rising diplomat in Japan's foreign ministry, she gave up that career to marry Crown Prince Naruhito in 1993, weathered years of intense public scrutiny with acknowledged difficulty, and became empress in 2019 at the start of the Reiwa era. Her story, of brilliance adapting itself to tradition, has made her a quietly admired figure far beyond Japan. In American records Masako is a genuine rarity, showing only the faintest trace, which means a name with an empress behind it and almost no one else wearing it.
