Higashisonogi
Eastern Sonogi lies around Ōmura Bay in western Hizen. The Ōmura family held lands here from the medieval period, when Ōmura formed part of the Sonogi estate. In the sixteenth century Ōmura Sumitada became a Christian and supported overseas trade and missionary activity. Under his successors the district became part of the Ōmura domain, while Sonogi developed as a post station where roads toward Saga, Hirado and Ōmura met.
