Emperor Naruhito’s wife, Empress Masako, wore the grand Meiji Tiara, which features as many as a thousand diamonds set in platinum. It’s the same crown her mother-in-law wore during Crown Prince Akihito's enthronement ceremony in 1990.
From Australia’s own Princess Mary of Denmark to the world’s youngest queen, Queen Jetsun Pema of Bhutan, the evening showcased an impressive display of tiaras all round.

59-year-old Naruhito is Japan's 126th emperor. He succeeded his father, Emperor Akihito, who became the first emperor to abdicate in over two centuries. Akihito reigned for 30 years but in 2016 he announced his desire to give up the throne after battling prostate cancer and heart surgery, among other health issues.
