- Japanese: 入内 (judai)
The ceremony in which a new principal imperial consort (nyôgo) entered the Imperial Court was known as judai. This ceremony dates back at least as far as the reign of Emperor Daigo (r. 897-930), and though it declined in the 14th century, it was revived, and practiced through the entry of Ichijô Haruko (the future Empress Dowager Shôken) into the Court of the Meiji Emperor. Their son, Crown Prince Yoshihito (the future Taishô Emperor) would be the first Japanese emperor to have a formal religious wedding ceremony.
