Kunigami was the eldest son of Kunigami Seikan, and was also a grandson of Kunigami Seiin. He served as Sanshikan during King Shō Gen's reign.

Amami Ōshima revolted and refused to pay tribute in 1571. A troops led by King Shō Gen to suppress them, but the king got sick seriously on the way. Kunigami prayed to heaven and said that he would like to replace the king to die. Magically, the king was full recovery and quickly put down the rebellion, but Kunigami died. The king was moved, and promoted his son, Kunigami Seichi, to the rank of Aji, and established an aristocrat family: Kunigami Udun. This was the only one Aji family which had no royal blood, and Kunigami Seikaku was regarded as the third head of Kunigami Udun posthumously.

馬順德為馬誠驥（國頭親方正鑑）的兒子。他的祖父馬思良（國頭親方正胤）出任過三司官。馬順德本人在嘉靖年間出任三司官。

1571年，尚元王御駕親征奄美大島，歸國途中病重。隨行出征的馬順德對天祈禱願代王死，最終尚元王病癒，馬順德卻病亡，對此尚元王非常感動。念及馬順德及其父、祖三代都為國盡忠，尚元王破格將其子馬似龍（國頭按司正致）的位階提升為只有王族才能擁有的「按司」，馬氏國頭御殿也成為琉球歷史上唯一一個沒有王族血統的御殿。
