Matsura Sadamu served as a bushō from the late Muromachi to Sengoku periods.  He served as the lord of Daichian Castle in Hizen Province.  Sadamu was the fourteenth head of the Aikōnoura-Matsura clan.

Sadamu was born as the son of Matsura Sakō.  After the death of his father, Sadamu inherited the Aikōnoura-Matsura from the direct lineage of the Matsura clan.  In 1490, Sadamu built the Kyōhō Temple in Setogoe, and new constructed Daichian Castle, moving his residence there from Tanabe Castle.  In 1491, upon solicitation by Arima Takazumi, Sadamu joined Takazumi, Ōmura Sumimasa, and members of the Shisa clan to launch an attack against Matsura Hirosada (the head of the Hirado-Matsura clan) at Minotsubo Castle.  This is known as the Battle of Minotsubo.  Sadamu died in 1492.

After suffering a defeat at the Battle of Minotsubo, Hirosada fled from Hirado to seek the support of Ōuchi Yoshioki.  Through mediation by Yoshioki, Hirosada recovered his former territory but remained deeply resentful toward to the Aikōnoura-Matsura and, years later, decimated Sadamu’s lineal heir, Matsura Masashi.
