Satsuma Province
The Tanegashima clan came to rule Tanegashima on behalf of the Nagoe family but soon became autonomous. It usually allied with, sometimes submitted itself to, and sometimes antagonized the Shimazu clan on mainland Kyūshū. The Tanegashima clan was given Yakushima and Kuchinoerabu Island by Shimazu Motohisa in 1415. In 1436, it was given the Seven Islands of Kawanabe District, Satsuma Province (the Tokara Islands) and other two islands by Shimazu Mochihisa, the head of a branch family.
