Takayoshi came from a family that had at one point been what amounted to pirates of the Inland Sea. The Murakami, which consisted of three branches, came under control of the Môri around 1550 and were instrumental in the 1555 victory at Miyajima. Takayoshi became the commander of the Môri's navy and defeated Oda naval forces at the First Battle of Kizugawaguchi (1576). In the Second Battle of Kizugawaguchi, however, Takayoshi's fleet was overcome by heavy warships built specifically to cut the naval supply lines to the Ishiyama Honganji. Takayoshi was technically subordinate to Kobayakawa Takakage.
