The Kaya (賀陽宮 Kaya-no-miya) (princely house) was the seventh oldest collateral branch (ōke) of the Japanese Imperial Family created from the Fushimi-no-miya, the oldest of the four branches of the imperial dynasty allowed to provide a successor to the Chrysanthemum throne should the main imperial line fail to produce an heir.
|Region of origin||Japan|
The Kaya-no-miya house was formed in 1892 as an ad personam title for Prince Kuninori, the second son of Prince Kuni Asahiko. Emperor Meiji authorized it to become an independent ōke household in 1900.
On October 14, 1947, Prince Kaya Tsunenori and his family lost their imperial status and became ordinary citizens, as part of the American Occupation's abolishment of the collateral branches of the Japanese Imperial family. The direct line of the Kaya-no-miya house died with the death of Prince Kaya Tsunenori’s eldest son, Prince Kaya Kuninaga in 1986.
The Kaya family name is continued through the line of Prince Kaya Tsunenori’s third son, Kaya Akinori.
