Minamoto no Tōru
Minamoto no Toru (822-895), a son of Emperor Saga, received the Minamoto surname in 838 and founded the Toru line of the Saga Genji. He rose to sadaijin in 872, though Fujiwara no Mototsune held the real power; after 876 Toru largely withdrew to his Kyoto villa.
His Kawara-no-in mansion, whose garden imitated the Shiogama scenery, and his Kokinshu poems made him famous; the Hyakunin Isshu calls him the Kawara Minister, and he is a leading candidate for the model of Hikaru Genji.
