- Japanese: 松浦家 (Matsuura ke)
The Matsuura of Hizen province had somewhat obscure origins, and may have originally been a collection of land-owners who united under the name 'Matsuura'. One theory holds that the Matsuura line that persisted into the Edo period was established by Minamoto no Hisashi, a descendant of Emperor Saga. The Matsuura, known for their naval power (and involvement in piracy), survived the Sengoku period and in the Edo period became lords of Hirado han.
