As UPI put it, Japan was “in the midst of a wedding boom” in 1964, where the Meiji Memorial Hall, very near the Olympic Village, was marrying 35 to 40 couples a day.
But the biggest wedding during the Olympics was between two Bulgarians, Nikolai Prodanov and Diana Yorgova. Held at the International Club in the Olympic Village, the wedding was attended by the Bulgarian Ambassador, Christo Zdravchev, as well as the President of the International Olympic Committee, Avery Brundage. Superstar gymnast, Takashi Ono and his wife joined the festivities, as Prodanov was a fellow gymnast.
As this was the first wedding ever at an Olympic Games, everybody likely wanted to be a part of the ceremony. A director of Nippon Rayon played the traditional role as the “go-between” and financed the couple’s 24-hour honeymoon to Kyoto, back in time to attend the closing ceremony.
