Was the marriage between the present emperor and the empress an arranged marriage?
No, it wasn't here is a bit of history, Lille1900
On 10 May 1900, 21-year-old Crown Prince Yoshihito married the 15-year-old Princess Kujō Sadako. The Princess – renowned for her intelligence and eloquence – was purportedly selected by the reigning Emperor Meiji to complement his son’s perceived flaws – among them, a lack of charisma and a disinterest in scholarly pursuits. The relations between the Emperor and Empress were positive, as evidenced by the Prince’s breaking with thousands of years of tradition in refusing concubines. The couple had four sons, and 12 years into marriage, the Crown Prince ascended the throne, where he reigned for 14 years.1924
Crown Prince Hirohito – the then-21-year-old son of Emperor Taisho – married his distant cousin Princess Nagako Kuni in January 1924. Unlike the strictly arranged marriages of Japan’s imperial tradition, Prince Hirohito was allowed to choose his own bride – at the age of 14, she and other eligible girls of nobility participated in a tea ceremony while the Crown Prince watched through a peephole to make his selection. They were married seven years later, and Princess Nagako bore seven children. 1959
The current Emperor of Japan was married in April 1959 to Michiko Shōda. The marriage of the then-Crown Prince Akihito broke with tradition – his bride of choice was the first commoner to marry into the Japanese Imperial Family. The Empress Kojun was said to have been against the union, and consequently bullied her daughter-in-law into two nervous breakdowns. Three children were born to the couple, and upon the death of Emperor Hirohito on January 7, 1989, the Crown Prince Akihito became Japan's reigning 125th Emperor and she became Empress Consort.1993
Naruhito, the reigning Crown Prince of Japan, was married in June 1993 to Masako Owada, who like her mother-in-law, is a commoner by birth. The Harvard-educated Crown Princess – fluent in six languages and formerly employed by the Japanese Ministry of Foreign Affairs – was said to have rejected the Prince’s proposals several times before finally honouring his request in December 1992, thus bringing her diplomatic career to an end.
