薩摩国
Some articles of 1187 of the "Azuma Kagami" state that during the period of the Taira clan's rule, Ata Tadakage of Satsuma Province fled to Kikaijima (貴海島). The "Azuma Kagami" also states that in 1188 Minamoto no Yoritomo, who soon became "shōgun", dispatched troops to pacify Kikaijima (貴賀井島). It was noted that the imperial court objected to the military expedition claiming that it was beyond Japan's administration.
