- Japanese: 千竃氏 (Chikama-shi)
The Chikama clan were retainers to the Hôjô clan, and in the 15th century controlled a section of Satsuma province. Extending their influence southward, they established some degree of control over (or perhaps merely trading posts located on) a number of islands in the northern Ryûkyû Islands, clashing at times with the newly founded Ryûkyû Kingdom.
