Koga family
noble family

The Koga family (久我家, Koga-ke) is a Japanese aristocratic family, a branch of the Minamoto clan that traces its descent from Emperor Murakami. The Koga lineage was classified as kuge prior to the Meiji Restoration, then as a kazoku lineage.
Name
The name Koga is composed of the kanji meaning 'long time' (久) and 'I/self' (我). 'Koga' is the on'yomi (Sino-Japanese reading) of the kanji. But actually 久我 is the ateji (当て字; phonetic-equivalent cv characters) for 陸 (koga; an obsolete word for land).
The name is recorded as having originated with the grandfather of the family's founder, Chancellor of the Realm Minamoto no Morofusa (ja:源師房), who owned a manor in the south-western suburbs of Kyoto at Koga (modern Fushimi-ku). As a result, he was referred to as the Koga-Chancellor. After the family's apparent founding, however, neither Minamoto no Masazane's (ja:源雅実) son nor his great-grandson were referred to by the name Koga. Strictly speaking, therefore, the 'Koga family' refers to the lineage descended from Minamoto no Masazane's great-great-grandson, Koga Michiteru, whereas those before should be considered as members of the Nakanoin section of the Murakami Genji branch of the Minamoto clan.
