The Matsuda's origins are obscure but by the end of the 15th Century they were a growing power in western Bizen province and clashed with the Akamatsu. They resisted the Akamatsu's efforts to subdue them and come to control Bizen's Asahi River valley. The Matsuda competed with the Urakami and by 1568 had been reduced largely due to the efforts of Ukita Naoie. They afterwards seem to have devoted themselves to religious affairs, in particular Nichiren Buddhism.
