Executives of the domain included owners of private estates, who were also concurrently appointed as the land stewards of their estates, as shown by the example of Kiyomoto KOMATSU, the owner of the estate of Yoshitoshi (present-day Yoshitoshi, Hiyoshi-cho, Hioki City), who was appointed as the land steward of Kiyomizu-go (present-day Kokubunkiyomizu-cho and other areas in Kirishima City).
また藩重役には私領主も就任していたので、例えば吉利（現在の日置市日吉町吉利）領主小松清猷が清水郷（現在の霧島市国分清水町他）地頭職に就任したように、私領主が地頭を兼任することもあった。
